Preps & Preparedness FGG

Been a busy week of tweaking and tuning here, with a welcome procession of test kit, to keep me focused and out of trouble. Summer prevails, despite the harbinger of doom  tabloid headlines. 

We're prioritising summer based chain preps and related stuff, at Seven Day Cyclist and I'm hoping to get some decent mileage on the Holdsworth before leaves start falling.  That said; the nights are drawing in that little bit faster now, which is ideal for testing lights. 

The majority of breakdowns are avoidable. Sure, there's always that hole/sharp with your name on it. The best maintained machines CAN let us down, but probability is very small. 

I've been alternating between fixed gear winter trainer and tubby tourer this week. Thundering along 1in 4s at 35mph, keeping up with the spiralling revs and putting the Clarks CMD22 through its paces. Paired to The now discontinued  Kinesis DC37 fork  and Cane Creek V brake lever https://www.sevendaycyclist.com/cane-creek-v-brake-drop-bar-levers, setup was a pig. 

I also had to switch to the TRP Spyre's mount, so the caliper didn't bind against the spokes. Quiet, methodical tweaking, diesel strength coffee and minute adjustments won the day. Formative impressions are very positive, although at this stage, I'm not convinced real world performance is superior to the TRP Spyre. 

Only time and real world miles, will tell.  A sentiment that applies to a wealth of other things. Dry lubes can take many forms, some ceramic blends, such as Weldtite TF2 which cure to a dry, yet surprisingly durable state. 

Others are closer to an oil and some, including Muc Off Dry https://www.sevendaycyclist.com/muc-off-dry-chain-lube and Oxford Mint Dry https://www.sevendaycyclist.com/oxford-mint-cycle-dry-lube are closer to emulsions in their consistency. Ceramics tend to require relatively long curing periods. However, the do run cleanest, in my experience. 

Wax and emulsions tend to melt in higher temperatures. This may look gunky but dirt and grime are locked within the outer layer. This ensures it doesn't form a transmission munching grinding paste, and given time, the grotty stuff will fall away. 

Most noticeably, when its solidified following a cooler period. Unfortunately, in their gooey state, they transfer more readily to hands and clothing. Not ideal, if you're commuting, or doing short "bikes as car" runs in smart trousers.

I carry a couple of latex examination gloves, should a flat/similar roadside mechanical strike. Good practice generally, especially if you are using petrochemical derived formulas.

Speaking of which Rock N' Roll Lubes' UK distributors have kindly sent me samples of the Gold LV and Extreme LV formulas. 

LV stands for low vapour, meaning they're non flammable, so can be transported in the post and on aircraft, without special precautions.  These are not oils, in the commonly accepted sense, so require a different delivery. Strip the chain and cassette of any pre-existing lube (including the factory stuff). 

Shift the chain to the middle of the cassette (as appropriate). Give the  Rock n' Roll a quick shake, undo the cap and apply a continuous flow of lubricant into the chain. Once you've built up a decent layering rotate the cranks for five seconds and clean any excess from the chain's side plates, derailleur jockey wheels etc.  

Now, leave it curing for a few hours. I'm told the Rock n' Roll family are completely compatible. 

Say you wanted to switch from their absolute dry https://www.sevendaycyclist.com/rock-n-roll-absolute-dry-chain-lube to the Extreme LV. There's no need  to go through the stripping rigmarole, simply deliver the Extreme on top. The solvents will remove the sibling product and leave the other in its place. 

They've also sent us some Miracle Red 3in1 degreaser. They tell me its a bio-degreaser, hand cleaner and stain remover. So, theoretically, you can purge stains from your bike, hands and soiled clothing. In the latter context, it should be applied neat to the affected area, then agitated with a finger nail, then rinsed.  

To date, I've used it to purge mildly mucky maulers and dilute as a bike wash, prior to waxing the Univega with this Naked Bikes Pro Bike Wax Special Edition. In common with several other boutique blends I've tested, this one is a hand poured blend of hard and soft waxes. 

Apparently, it contains Si02 technology and reckoned to last uyp to 12 months between applications. In my experience boutique waxes, though expensive, relative to polymer based car types, do last a good while. 

However, I suspect the maximum periods cited are perhaps, based upon machines in dry storage, rather than daily service. Judging by my Univega, the rich glossy effect is impressive, although, unlike Velo21 Ultimate Paintwork Protection https://www.sevendaycyclist.com/velo-21 , there's no mention of compatibility with matt finishes.  

Naked Bikes also sent their Bike Bling and Chain Cleaner. The former is a quick n' convenient detailer, the sort that really brings out the sheen.  Ideally, give recipient bikes a sudsy bucket wash first. Unlike the Pro Green MX Aftershine101 https://www.sevendaycyclist.com/pro-green-mx-triple-pack, which is literally blow n' go,  

Bike Bling has to be worked in, then buffed to a shine. Hardly a hardship mind. 

Every now and then, small miscellaneous parts need running repairs. My tubby tourer's otherwise fabulous Exposure Revo MK1 dynamo wiring was looking a touch weary just above the plug. 

Heat shrink was my first idea. I was halfway to ordering some, when I discovered this Thermoworx White morph. Its a versatile polymer along the same lines as Sugru. 

Only, it can be re-used. Set too quick? Apply a hairdryer to it, and gently reshape. It reacts with hot water (62 degrees upwards). So, decant some of the beads into an old cup, boil a kettle and pour in. 

Stir (an old, clean spoke seems perfect) until it assumes a sticky, toffee like consistency. Mould, apply and leave to set. Setting is VERY rapid, so you need to be prepared to work, apply, and shape quickly.  Strictly speaking, its a modification/ "hacking" rather than repair product in the conventional sense. 

Aside from the damaged outer dynamo cabling, I've added "scuff bumpers" to my Univega's Microshift Brifters, made replacement end caps for the mudguard stays and sealed freshly spruned cable ends. Pretty confident I'll find several others. Bike related, and otherwise. 

Melting, Musing, Blasting & Stopping

Not surprising perhaps, since the UK has recently experienced, the hottest day on record. It was a stonking hot week, at least here in the South East. Even nocturnal rides, testing lights, were close and muggy-hovering around 24 degrees. 

Day rides, saw emulsion and wax types chain lubes melt. Literally coating the drive-side crank arms in a sticky residual layer. On that quickly contaminated shoes. Thankfully, these were easily dismissed with a gentle solvent. 

Beeswax furniture polish for the crank arms, leather conditioner cum food, the shoes. Internal frame preserves have also turned very fluid, but not to the stage where its gushing from the frames "breathe holes" , engulfing the chainstays/hub etc. 

I can function well enough in these temperatures, although maintaining a steady 20 mph for 20 miles, can be challenging-even with sufficient fluids. Designs like the back bottle (link & photograph) come into their own.  Though there are some minor downsides, I've come to really appreciate the Relaj Shape Bottle's design too.

Popping ice (or pour 70% full of water, then freeze) and placing in a jersey pocket brings welcome, cooling relief. I'm also pleased to report the Funkier Force Pro Bib shorts https://www.sevendaycyclist.com/funkier-force-pro-bib-shorts  have certainly cut it in the comfortt stakes. They also offer plenty of bang, for very modest buck, in other respects, too.  

For the most part, I'm resistant to testing new shorts and saddles, in case both are mutually incompatible. Far fairer to run an old favourite and see how things measure up. Hygiene aside; I have alternated between different bibs to see how the saddle covering behaves. 

Am I able to make minute adjustments, am I surfing around, or do I feel like I'm perched atop a sheet of flypaper? The first scenario, is my particular sweet spot. Now, I would appear to have braking on the brain, at the minute, at least given my last few entries. 

Only because the more powerful and controlled my machine's stopping prowess, the faster I can go (to a point and within reason). Some would argue (with some justification) that a disc setup is overkill on a fixed. True, a well-honed cantilever will haul me and 20 kilos of payload to a controlled, predictable halt-even along a 1in 7 pushing 30 odd mph. 

However, on a four season's machine, one running a single stopper, disc is an obvious choice. I have run Tektro Spyre on mine, for several years now. Its a twin piston design, widely regarded the benchmark for cable operated systems. A sentiment I'd agree with. 

However, time and technology marches on. I've been keen to try Clarks CMD22 Dual Piston disc brake and Rever MCX1 systems to see if they have an edge. Dual piston designs have several advantages over single pistons, such  as Avid BB5 and BB7. 

Firstly, both pistons move an equal distance, thus connect evenly with the disc rotor. Therefore, even wear of both consumables, superior modulation and feel. They're also markedly easier to setup and maintain. There are some folks who "advocate" consigning the humble cable-operated disc, to the vaults of history. 

Modern hydraulic systems win hands down, in competitive contexts. No need to dial in the pads to compensate for wear, open systems do that automatically. 

Indeed, provided you don't kink/damage the hose, stick to the correct fluid and observe service intervals, they're fit n' forget. A few months back, I was lusting after TRP Hylex but couldn't secure a set, at the right price. 

I've no doubt they'd convert me within a matter of lever actuations, mind. Such lust has been tempered by the arrival of these Clarks CM22, which I shall whip aboard and dial in very shortly.  

160mm rotors have been my default, as they have an advantage in the stopping stakes (although some suggest 140mm, are fine for 'cyclo cross). 

Never be tempted to skimp of cable quality, mind. These are also central to getting the very best from them. I'd suggest compressionless, and decent cutters. Something like these Jagwire Pro Road https://www.sevendaycyclist.com/jagwire-pro-road-brake-kit and Super B TBWC30 Cable Cutters https://www.sevendaycyclist.com/super-b-tb-wc30-pro-cable-cutters

Not that I was going to go very far with a flat tyre. To my surprise, my working fixed's ultra dependable Schwalbe Marathon GT, had succumbed to a flat. No sign of anything sharp in the casing, so I fed it a tube from my tube rack, along with another spare for the SQR Tour. 

Wheel, home, chain correctly tensioned and we're ready to let the good tmes roll again.   I will probably switch to the Vee Rubber Zilent Tyre, once the Maraton GT comes of pensionable age. https://www.sevendaycyclist.com/vee-tire-co-zilent-tyre   It'll save a few grams too, especially the 35mm (as big as said bike's rear triangle will entertain). 

Several hundred miles in, I'm not surprised the fixed's SRAM has negligible wear. As a rough n' ready, even through a harsh winter, I can  expect 3,000 miles from a fixed chain. Nonetheless, and regardless of your chain types, its good to check their health frequently. 

Replacing chains by, or before wear hits 0.8mm, saves a lot of unnecessary erosion, and ultimately, expense replacing rings, cassettes and other components. I prefer the digital models but simple, nickle plated anaologue models give change from £5.   https://www.sevendaycyclist.com/torque-chain-checker

Cantering Along

Another 120 miles on my tubby tourer, pleased with the recent revisions, I decided it was time to dial in the Genetic CX cantilevers. There was a little too much lever travel, for my tastes. Thankfully, they’re much easier to hone, than the otherwise impressive IRD CAFAM2. Pull cable and straddle wires through a few mm, tweak balance screws-Result!

Switched to The Muc-Off Dry Lube, since opportunity presented. A freshly cleaned and lubricated chain always makes the drivetrain feel that bit fresher. However, 100 miles or so later, I'm increasingly forming the opinion that friction is lower than the Zefal Pro Dry Chain Lube https://www.sevendaycyclist.com/zefal-pro-dry-lube and Finish Line Dry lubes https://www.sevendaycyclist.com/finish-line-dry-bike-lube  which is going some.  

Shifting feels almost instantaneous, in both directions across the block, even under load. The pronounced lack of friction just encouraged me to increase my temp. I’ve also concluded gearing is bang on, for the riding contexts intended.

Admittedly, I could go slightly lower, for heavier trailer loads, but for time being I’ll leave be. Durability is another consideration (especially given the Muc-Off Dry Lube’s relatively long curing period).

However, I’ve gone past the 160-mile stage without any hint of waning. In common with some wax formulas, several days at 23-28 degrees, and its assumed that fluid consistency. Lubricant has seeped deep within the chain, and a filmy, residual layer is clinging to the cassette. It’s also quite tacky to touch, though transfer to fingers/clothing hasn’t proved overly problematic, thus far.

For some folks, the lube debate is binary i.e. if you’re riding in wet/changeable weather, stick to a wet formula. Dry, for arid, dusty conditions. However, given the UK’s notoriously changeable climate, I like something that can bridge the gap, resisting those unpredictable showery periods, without attracting a gungy beard. 

That said and testing aside; chances are you’ll find my chains running a stoical wet formula, such as Weldtite TF2 Extreme wet chain lube https://www.sevendaycyclist.com/weldtite-tf2-extreme-wet-chain-lubr  or, if I want to keep maintenance times down, something like SKS lube your chain, which locks the grot within the top layer. https://www.sevendaycyclist.com/sks-lube-your-chain

This might look unsightly but is “embalming” the chain. Crap eventually flakes away in chunks, leaving only a layer of lubricant behind.  Here’s an overview to lubes, if you’re new to riding, or want to explore the best option(s), for you. https://www.sevendaycyclist.com/blank-ao363

Elsewhere, I’m also warming to the Oxford Contour flow saddle. 120 mixed terrain miles in, the relatively narrow profile and sensibly proportioned padding density are proving a winner for my derriere. I was slightly surprised to discover the rails are a solid steel, which would probably explain the weight differential, compared with those sporting hollow Cro-moly. 

4130 is common at this price point too, and my preference.

Is it a deal breaker? Not necessarily, why bemoan a few grams, if the saddle fits your shape and goes unnoticed, in the most positive sense. Will give it another 250 miles before reaching a conclusive verdict, mind.

Those seeking a wallet friendly 6061 post, with classic lines might be interested in Steve’s review of the Genetic Heritage II sea tposthttps://www.sevendaycyclist.com/genetic-heritage-ii-seat-post  . Right, off to play with the Ravemen PR1200 USB Rechargeable Dual lens Front Light.

Tighten Thy Top Cap !!!

Some of you may recall I'd been trying to diagnose a small but low level rattle, on my fixed gear winter/trainer. Some minor jingle is attributable to a bag of fasteners, tucked away in the depths of its SQR Tour bag. The Eureka moment struck, not while screaming along a 1 in 4 at 35mph, but grinding along a long, deceptively flat section of washboard tarmac. 

https://www.facebook.com/Sevendaycyclistmagazine/videos/380414165945084/?notif_id=1563290229476148&notif_t=page_post_reaction

This frustrating percussion was traced to an aluminium spacer drumming against the top-cap and Redshift Sports Shock Stop Suspension stem https://www.sevendaycyclist.com/red , indicating the Gusset Headlock, had worked slightly loose.  For those unfamiliar with the system, its a more secure alternative to the humble Star Fangled Nut. It comprises of a CNC machined top cap, cro-moly bolt and alloy nut. 

Aside from keeping the bearing tension bang on, theoretically it offers some additional security in the event of (gulp) steerer failure. The system  carries a slight weight penalty, requires some filing and subtle bending of mudguard (fender) mounts. They're also incompatible with dual pivot and other side-pull brakes. However, I consider them a definite upgrade for machines with cantilever/V/Disc stoppers.   

For some reason, I  couldn't locate my multi tool, by the roadside. However, I was only three miles from home. Snugged tight, I slipped this GT multi-tool in the SQR Tour's side pocket, for easy access.  Talking of SQR, while fitting this Oxford Contour flow saddle, I investigated my Univega's slightly "sticky" SQR bracket.   

Removing and compressing the spring, then reinstating the red, quick release mechanism proved the solution. In retrospect, a quick blast of Muc-Off Silicon shine https://www.sevendaycyclist.com/muc-off-silicone-shine-polish might've done. 

However, sometimes its best to strip and inspect, especially if you haven't in a while. The bag rails now lock securely within the bracket. Never had any ejection issues, when riding, but the Carradry bag https://www.sevendaycyclist.com/carradice-carradry had a tendency to sneak from the bracket, when the bike was hanging up. 

Apparently, the Oxford Contour Flow, is "Aimed at the middling cycling enthusiast those who have just started to be gripped by the unrelenting claws of cycling passion". 

Its a sensibly narrow design, with a gender specific cutout, gel padding and seemingly neat construction.  Will be interesting to see how it compares with the Selle Italia Sport Gel Flow FEC alloy saddle. The latter is 20g lighter but weight hasn't been the reason behind its residency, a few thousand miles down the line. 

Reverting to the bike's original fork has brought a quicker, more compliant persona. Not that handling, or responsiveness was remotely average beforehand but the trials fork was portly compared to the relatively delicate looking triple butted Cro-moly originals. The Microshift Centos' standard lever travel works a treat with the Genetic CX cantilevers too.  

So glad I switched. 

I'm also very glad I swerved this "documentary" from Channel 5 https://www.channel5.com/show/cyclists-scourge-of-the-streets/ I must admit, it was reeling me in, like a super visceral horror film. the sort you really don't want to see, yet feel strongly compelled by.  

Knowing it would serve no purpose, save for raising my blood pressure, I popped out on the fixed. 

Thankfully, Chris Boardman responded in his usual, measured, reasoned and articulate way.  https://twitter.com/BritishCycling/status/1148622845695557632  All the more poignient, and dignified given his mother was  killed by a "distracted" driver. 

 Back to multi-tools, designs such as Blackburn Switch https://www.sevendaycyclist.com/blackburn-switch-multi-tool have some definite advantages. However, because the bits detach, there's the real risk of losing one (or more) out in the wildes. This also serves as timely reminder, to check condition and supply of spares/tooling. Particularly those belonging to mile munching working bikes. 

140 miles in, and I'm warming to the Muc-Off dry lube, which seems surprisingly low on the friction front.  Level-pegging with Zefal Pro Dry Chain Lube  https://www.sevendaycyclist.com/zefal-pro-dry-lube  , although the Zefal is cheaper and doesn't have a prescribed curing time. 

On the face of things, suggesting its more practical for commuting, impromptu rides with friends, and of course, summer touring. Having tested its PTFE infused predecessor some years back, I'm curious to how this version compares.

 Most dry lubes (excluding hardier ceramics) should return around 225 spring/summer miles from a single helping (roughly ten days/two weeks riding. Given the asking price, I'd be very disappointed if it didn't top this.

Cleanliness is impressive, no more evidence of contaminant, than the Zefal, or indeed Finish Line Dry https://www.sevendaycyclist.com/finish-line-dry-bike-lube. It transfers less readily to hands/clothing too, which is a definite plus.

On the subject of dry. Rather than simply scabbing away, Zefal Extra Dry Premium Chain Wax https://www.sevendaycyclist.com/zefal-extra-dry-chain-wax seems to melt, when temperatures climb to the mid 20s. A helpful phenomenon, that redistributes lubricant, trafficking it deep within the chain, cleat and similar mechanisms. 

Forks & Functionality

I'm someone who keeps "doing" (as distinct from "to-do") lists. These are organic, and used to structure, and critically analyse how effectively I'm using time, and other resources. "To do lists are full of good intentions, but few results. Some might even describe them as "where good ideas go to die".

That established, instatiing the Univega's original (and recently refurbed) forks were on Saturday's agenda.

Organisation i.e. laying out tools, parts etc are all part of productivity. I'd suspected the long serving Tortec guards' stays were close to pensionable, so retrieved an SKS set, just in case. 

Next came the crown race removal and setting tools, grease, Allen keys, two sets of cable cutters (Premium for cables, cheap n' cheerfuls for cable ties, and similar donkey work).  

Going off piste, I decided to switch to these Genetic CX Cantilevers https://www.sevendaycyclist.com/genetic-cx-cantilever-brakes . I'm very fond of the IRD CAFAM 2 https://www.sevendaycyclist.com/ird-cafam-2-cantilever-brakes but fancied a change, and besides, the Genetic are much easier to set up. 

I love a really firm, positive action, so set the spring tension to maximum, greased the "new" forks canti posts with Park PPL1 Poly lube and popped them aboard, before turning my attentions to disassembling the Univega's existing front end. Being a daily driver, I was pleasantly surprised by how easily everything released.  

Full length mudguards (fenders) keep a remarkable amount of corrosive filth, from rider and machine, extending servicing times and ultimately, component life. I was pleasantly surprised by how much, effective Muc-Off Bio Grease https://www.sevendaycyclist.com/muc-off-bio-grease-long-term-test was still in evidence. Old "School chair" trials fork out. I gave the Aheadset's bottom race cursory inspection, before delivering a fresh helping, of the jam-ike grease.  

Be rude (and silly) not to.  I replace headsets/ forks maybe once yearly, so find this  wallet friendly Ice Toolz crown race remover perfectly adequate. a few even taps later, I'd extracted the crown race and fitted it to the "new" forks, using my  Cyclo setting tool. 

Scrap "Gas pipe" down tubes make excellent, zero-cost alternatives, although ensure these have been cut cleanly, and accurately...

From this point, everything came back together, sans drama. Wheel reinstated, brakes setup, mudguard hardware greased and snugged tight, it was simply a case of setting bearing tension, trimming cables and naturally, treating the fork to some  Velo 21 Ultimate paintwork protection https://www.sevendaycyclist.com/velo-21 .  

I also took this opportunity to blast some corrosion inhibiting products inside the breathe holes, before hanging the bike up. This encourages it to travel through, and evenly coat the hosts. In a pinch, anything  (petrochemical) oily will do. A teaspoon, or two of 10w/40 motor oil inside a frame, or delivered into the fork blades, via syringe will certainly help. 

I chose to use up an almost exhausted aerosol, of waxy chain lube. Given the temperate weather, it should melt nicely and distribute evenly within their inner sanctum.  Talking of which, Steve's been putting some Boeshield T-9 Bicycle Lube & Protectant through its paces 

https://www.sevendaycyclist.com/boeshield-t-9  

Last but not least, for this "sitting"; dynamo cable and computer sensors were tethered, to their respective blades. Weight might be a lesser consideration on a working bike and ultimately, I didn't weigh both forks. However, anecdotally, the  originals are noticeably lighter (gun to my head, probably 300g), which for me, is another bonus.

Knew there was a reason I squirreled them away...

Continuing the working bike theme, co-editor Steve Dyster has been putting Bristol Bicycles Touring Bike through its paces and seems pleasantly surprised by its blend of fun and practicality. 

https://www.sevendaycyclist.com/bristol-bikes-touring 

Elsewhere, I've commenced testing Muc Off Dry Lube, which has a hue and odour, reminiscent of banana ice cream. It also has a recommended curing time of 4 hours, hence one I'd be inclined to re/apply the evening before riding. Once cured, it seems closer to a "diet" wax formula. 

A formative forty mile blast suggests friction's lower than a snake's testicles but I'll reserve any kind of proper judgement, for another 250, or so. Be interesting to see how it compares with the quick curing Zefal Pro Dry https://www.sevendaycyclist.com/zefal-pro-dry-lube,
