Calculated Gambles

 

 I’d been pondering whether the Shimano Ultegra dynohub’s grease had turned to watery gravy and needed to investigate. I’d always understood Shimano, unlike Shutter Precision, were partially user serviceable. The right side could be stripped and overhauled using a 15mm cone spanner and 17mm for the locknut. Trepidation cast aside, I rounded up spanners, greases, clean rags and solvent. The locknut was quite stubborn, which in some respects is a good sign, but submitted without recourse to penetrant spray.

 Locknut and cone removed, the grease had assumed an oily, but still functional state. The loose balls and bearing races were also free of pitting and similar wear. I toyed with the idea of repacking with Juice Lubes Slick Juice but reached for their Bearing Juice The Juice Lubes Bearing Juice Long Term | cycling-not-racing on the grounds of outright staying prowess. Even allowing for the recent heatwave, viscosity meant it was a little messier to apply but no issues once I’d transferred the excess to the cone.

This would also help seal the elements out. Getting the bearing tension bang on took four attempts. Back in the forks, neurotic checking revealed zero play. Hub strips tend to be annual, or thereabouts, so I can get away with some cheap but cheerful cone spanners. Unlike some cheapies, Lifeline seem accurately machined and sturdy enough for periodic use.

I’ve since invested in this 15mm Park, replacing the Tacx someone borrowed and felt entitled to keep.  I took the Slick Juice route with the trailer’s hub, which, as expected has reduced friction. Will be interesting to see how well it stands up to the elements, especially since it's right in the firing line of puddles and other dodgy water.  I’ve periodically had the idea of upgrading the trailer’s wheel but talked myself out of it. A New Old Stock Deore unit was waved under my nose for less than £8, so I indulged. I’ll seek out a suitable rim, but only at the right price, since all this is want, not need.  

Overhaul complete, I treated Denise to a deep clean. Though not obviously dirty, given the prolonged, dry spell, rear wheel, rack, rear triangle and fork crowns were coated in a stubborn dusty layer. Buckets, Muc-Off Chain Wax Cleaner Muc-Off Chain Wax Cleaner 500ml | cycling-not-racing, Juice Lubes Bike Cleaner, Muc-Off MO94 Muc-Off MO94 Multi Use Spray | cycling-not-racing and assorted brushes rounded up, twenty minutes later, Denise was washed, dried and lightly re-lubed. Knowing when to down tools and pack up-quitting while ahead is another important skill. Sometimes, if it aint broke, don’t fix it.  

 The chain was still below .25 on the chain wear indicator, and I was going to run the fleet on wax lubes for as long as conditions permitted. Back to testing Ursula’s M Part Ridge Pannier rack and some fixed gear frolicking aboard Muffin. Having discovered the Ride’s top section broader than the Summit-confirmed when strapping my long serving Carradice Super C atop.

This was filthy, so I decided to take it for a thirty-degree Tour De Zanussi, adding some wash-in proofing. Now, this isn’t strictly the way to treat cotton duck, so a gamble at my own risk. However, it seems to have emerged in good health. I decided to take my 25-year-old SQR Tour the same route since, while very solid, it was looking very jaded. The sun and other elements had bleached the fabric in places and there’s no getting that back, but it was at least, clean and re-proofed.   

This also presented the ideal opportunity to give the washing machine’s soap try a thorough cleaning to remove accumulated soap scum and similar.

 Ideally, we should follow manufacturer instructions regarding care to the letter and have no recourse, should we deviate. Those of you looking to reproof cotton duck luggage should give them a good wash and then apply Carradice’s own reproofing wax.  I even found a box of high-quality patches, which was another pleasant surprise.

One thing led to another. I decided it was high time I had a sort through of the work bench. I decanted a myriad of small fasteners, mounts and similar into dedicated zip lock baggies and found and appropriate storage box. I’d been slightly disappointed by the OEM Coospo CS600 Coospo CS600 GPS | cycling-not-racing Garmin pattern mount adorning Ursula’s bars but hadn’t found a suitable contender.

Firmly in the zone, I discovered a couple of Magicshine mounts- the type employed on the marque’s Allty and Ray series. These employ a Garmin pattern head mount and a series of straps, so a universal fit. One, already attached was in Goldilocks territory. Sixty seconds later, a neater, sturdier host. A small but very satisfying upgrade.

Next, I decided to road test my hypothesis that wrapping some scrap inner tube around the quick-release trailer hitches would act as a damper. One producing a tighter union, silencing a slight rattle.  Formative impressions are favourable, although trailer release is less convenient than ideal. Maybe thinner tube, or even electrical tape is the solution... 

 

 

 

       

Momentum, Spuds & Mounts

 

I knew THAT idea was becoming the ONLY idea...The urge to switch Ursula's bar, stem, and brake levers. However, I wanted to avoid being midway through the transplant only to be thwarted by a spacer, or control cable- I strongly suspected the Jagwire Road Elite Sealed Cable Jagwire Road Elite Sealed Brake Kit | cycling-not-racing outers would be a little short at key points. Happy to take my time but crucially get things bang on first time and as with so many things, forward planning is key. I was also trying to trace some Shimano M505 pedals. These had long been succeeded, some might say eclipsed by the legendary 520 but I was curious as to where mine had vanished to.

Presented a good time to strip and re-grease the legendary original 1990 Spuds and I knew precisely where these were.  Balmy weather had seen me spend several weeks racking up a few hundred miles aboard the Holdsworth, enjoying its minimalist, spirited charms.  Clearly, it didn't appreciate the Garmin light mount, which I discovered ejected to an inaccessible part of the garage. This prompted a switch from the ultra-compact Magicshine Allty 400 to Ravemen LR1000 Ravemen LR 1000 Curved Lens Front Light | cycling-not-racing, which is a similarly compact light with a lot more useable power and thanks to the clever optics, much brighter than numbers alone would suggest.

Same goes for its 500-lumen sibling RAVEMEN LR500S FRONT LIGHT | cycling-not-racing. However, the 1000lumens ensures I can navigate the darker lanes, should I find myself out longer than intended on a summer evening.  Staying with lights, Gaciron got in touch and sent me their recently launched Xiaoman 1000 Multifunctional All-in-One Professional Outdoor Front light.

Aside from being a bike light, it's designed for other outdoor activities, including night fishing and hiking. Thanks to the diffusers, it could double as a reading lamp-it may also prove useful in photographic applications- we'll see. The Xiaoman 1000 will also double as a power bank and features a 5000mAh battery.

The highest 1000 lumen mode is claimed to have an illumination range of 200 metres and 2 hours runtime. I was pleased by the sensible staircasing downwards- 600, 300, 100 lumens catering for most riding contexts-great news for urban riders who like to let their hair down along the backroads, or ride through a variety of environments.

There's also a 300-lumen day flash reckoned good for 35 hours between charges and a "Breathe" mode alternating between 50 and 100lumens. Characteristics that lend it nicely to dynamo companionship. IPX6 for weatherproofing and aluminium construction bodes well for durability. There are three colour options-I've gone for black, but white or pink are the alternatives.

It can be mounted atop, or beneath the bars for a sleek, uncluttered effect, courtesy of the symmetrical optics, which is increasingly standard but welcome, nonetheless. I was very slightly disappointed to note the remote is only offered as an aftermarket option- I'd rather see this thrown in with the package, even if it meant upping the price by a couple of quid. 

Gaciron aren't alone in this omission but it's a niggle of mine.  I’m not endeared to the OEM mount design, which is very similar to that employed by Cat-Eye and prone to slippage. I’m looking into a suitable out-front extension mount. The sort that attaches via the stem face, theoretically eliminating the slippage, especially when paired with this Coospo Real Road CS600 GPS Bike Computer Coospo CS600 GPS | cycling-not-racing

 Having popped the Holdsworth back on its hook, having racked up some proper miles and fully reacquainted myself with Cinelli’s Classic Cork Wrap, Muffin and I have settled to some serious miles with the Genetic H-Grip Handlebar Tape, which is proving grippy and supportive. The 18-tooth sprocket has given some welcome additional torque on the climbs-especially when traffic’s slower, or I’m stuck behind a tractor.

It has also led to contemplating a slightly lower ratio for the Holdsworth, but we are talking the contemplative phase, and I do like the taller ratio when belting along. Presently, we’re turning a 79.1-inch gear, switching to a 17tooth would mean 74.5. I’ll give it further thought and may take this route, should I ned to switch a tyre. The Freedom Thick Slick is a very durable slick with great puncture-repelling qualities, but I’ve noted some very subtle deterioration of the sidewall.

One that’s not setting my Lycra ablaze but will be monitored carefully. A blowout might be amusing for onlookers, but I’ve no intention of being the object of someone else’s ridicule. I’d also toyed with upgrading the bottom bracket for a Genetic Karyotype and indeed, taking that route with Muffin next time (although arguably the Karyotype’s minor weight savings don’t justify the additional cost on a trainer, or working bike). I’ll either go for another UN300, or Genetic Cromozone.

Some folks have commented that the Stronglight track 2000 crankset is “made of cheese” citing stripped threads, specifically. I’ve not had any issues, although it’s worth saying I’m religious when it comes to re/greasing threaded components.  That said, should I ever need to retire it, I’d go for another Genetic Tibia GENETIC TIBIA TRACK CRANKS & RING | cycling-not-racing- in silver and possibly 165mm (they’re available in 165, 170 and 175mm).

 

Waxes & Inner Whippets

 

I’ve been pleasantly surprised by the KMC Go wax chain lube. Arguably a chain manufacturer of their magnitude would be expected to produce a decent lube. There are some limitations and I’d still say, in keeping with the Weldtite Wax Weldtite Wax Lube | cycling-not-racing  it’s a fair weather, three seasons lube. One that copes better in damper conditions than typically associated with wax formulas.

Wild and windy weather aside, conditions continue to become more spring-like, prompting me to switch Ursula back over to the CST Patrol CST Patrol Folding EPS Tyres | cycling-not-racing. An easy switch, or so I thought…A seized, or at least recalcitrant front Spyre SLC calliper prompted a strip and clean. I switched the pads since I was there. The existing pair were ok and good enough as contingencies-I just need to gently sand some light glaze and similar crap from them. 

Continuing this waxy flavour, Muc-Off waved their Dark Energy Chain Wax. Claimed to be four years in the making and suitable for road, gravel and mountain biking. Made from “plant-based biodegradable waxes” and free from PFAS and PTFE. It’s a dropper wax intended to narrow the gaps between dropper and immersion types. The latter, as the term suggests are where the chai is immersed and left in the wax, refitted afterwards. Not a new concept by any means and “baking” chains was once popular in motorcycling circles.  

Sigma sent me their Nyte Clip and Nyte 70 rear lights. Starting with the Nyte Clip, this is designed with versatility in mind and it’s not cycling specific, which isn’t always a bad thing. it can be attached to rucksacks, bike luggage, clothing etc, so also lends itself to hiking, walking, trail running etc.

It’s a very compact, some might say bijous measuring 52x21x21mm (width length height) and uses COB (Chips on Board) technology-36 diodes in this space is impressive and the 220degree projection continues tis narrative. There are six modes in total-two steady and four flashing (70, 80, 95 and 100lumens), with a maximum run time of 10hours in the 20-lumen steady mode from a full 90-minute charge.  

Sigma claim its visible to 500metres and this is very plausible, judging by what I’ve witnessed from the flashing modes on some bright morning rides.   By contrast, the Nyte70 is cycling specific and features braking and emergency braking functions, meaning it emits a very powerful blast of light when it detects steady, or rapid deceleration. It also employs COB technology, although this time 20 diodes share the space.

It also features an auto mode, which brings the light on and chooses output according to ambient light sensors. In auto mode the braking and emergency braking functions don’t work. There are five others, which seem considerably brighter than figures would imply. The high steady is only 9.5 lumens, the low steady 5.5, day flash 30 lumens, night flash 7.4 and the eco flash a mere 3.

However, its considerably brighter than I was expecting. Without seeing the figures, I believed the day flash to be around the 70-lumen mark.  Eco flash is claimed to return 20 hours from a full charge, night flash 8 hours and the day flash 6, which might not be astonishing, but gives reasonable scope for longer rides.

There’s an integral charge life indicator- green denotes full to 20% blue denotes 19-10% and blue flashing says you’ve dropped below 10%.  It can be mounted vertically, or horizontally, on a seat post, the saddle rails, seat stays and indeed, some racks.      

Elsewhere, I recently dropped processed sugar, or at least as much as I could from my diet and am generally feeling much better for doing so. Chocolate, sugar, cakes, deserts etc all gone. While intellectually I am someone of nuance, with some things I am all, or nothing and just need to stop wholesale, rather than “cutting down”.

I've certainly noted the benefits in the saddle, being able to accelerate and climb quicker, without fatigue, or sluggishness. The Coospo CS600 head unit with its comprehensive readout including calories consumed is certainly fuelling a desire to push myself a little harder. The radar function is also very welcome during blustery rides, and the ANT+ communicates seamlessly with either the brands' own TR70 or BBB radar taillights. The two faint green lines and widget in the left corner, coupled with audible beeps announce when vehicle(s) are approaching and their proximity.

I'd a few Garmin light mounts bouncing around the bodge box, but they were a little flimsy, so I bought two auction site cheapies for Muffin and Ursula, meaning I could simply port the CS600 between them. I had a Magicshine mount, but it was way too lofty for my needs. Buying two was cheaper still, since I wasn't paying postage. One affixing to the stem bolts was an option, but would've placed the CS600 (and indeed, other equipment) too close, especially given Ursula's very stubby stem.  

I found myself revisiting rings for Muffin- get something inexpensive and solid as a staple for next time and I also began contemplating replacing Denise's cassette for an 11-28 next chain switch, since that's the Tiagra rear mech's maximum capacity and would provide a little more winching prowess. In terms of ring, I couldn't find anything suitable- I was thinking sturdy, rather than exotic. A 42 tooth Gebhardt ring seemed the obvious choice. As for the cassette, I was sure I had a Tiagra 11-28 squirreled away somewhere, but at this stage, there's a few months before this becomes pressing.  I’ll close here with my review of the Coospo TR70 Radar Taillight Coospo TR70 Radar Taillight | cycling-not-racing

On The Radar

 

I wasn’t expecting to get so engrossed in radar-based technology. I’m specifically referring to systems such as the Coospo TR70 and BBB Signal Radar. Lights are to some extent evolving like mobile (cell) phones did i.e. from telephones through to the complex computers in our pockets. For the uninitiated, radar technology in bike lights is designed to pinpoint approaching vehicles from a safe distance and typically communicate this via smartphone app.

The apps typically allow you to select lighting modes and other functions. These are not intended to replace wider awareness-regular over-the-shoulder glances, but to increase safety, say in contexts, such as a very windy descent where we’re battling the elements and can’t hear approaching traffic. The technology has obvious benefits to folks towing trailers, tagalongs behind their solos and indeed tandems.

I was curious as to how far light/radar could be positioned before reliable, seamless Bluetooth/ANT+ communication was affected. Coospo tell me the TR70 is good for ten metres, which should cater for most applications and contexts.  The BBB signal can also be run sans app, courtesy of an integrated speaker, which is a nice touch.

Run times in both units are reassuringly long, thanks to the sensible selection of modes and varied outputs. Up to a claimed 40 hours with the TR70 and 14 with BBB’s Signal (both in radar only mode, which means the light is only triggered when the radar senses a vehicle approaching. 140 metres seems the benchmark, although the Signal is claimed to detect from 190 metres.  

Thus far, I am forming the conclusion that radar systems are most effective and accurate along country lanes, A roads and bigger roundabouts. The density of town and city centre traffic (parked and mobile) tends to instigate false readings from parked cars and sometimes steel structures and fencing.  

Having confirmed good, user-friendly compatibility with an Android handset, I was curious as to their relationship with a contemporary computer. The sort with internet connectivity. The sort that I’ve traditionally shunned. Coospo kindly sent me their Real Road CS600 GPS Computer, which has impressive features and generous run to charge ratios. I’m at the exploratory phase, so will reserve further comment until I’ve done a good handful of rides and some proper miles.

Talking of miles, after a really filthy ride, I took it as my cue to (a) clean Muffin (b) replace the Izumi chain, which I’d noted was showing some signs of wear. There was a fair bit of congealed go around the sprocket and ring, so these were given a good blast of Drivetrain Detox and a moderate scrubbing first.

Chains are relatively inexpensive, so best replaced before they consume rings and sprockets, which can work out pricey, even on a fixed. I’m still contemplating switching to a stainless ring before next winter comes around. A KMC Z510HX (as shown here on the Holdsworth) being the choice this time round. It features a decent silver finish, “anti drop technology” and mushroom pins promising greater strength.

Not the lightest, but reliability trumps that by some margin.  I’ve found them strong, inexpensive and relatively refined 1500miles seems the going rate for a mid- range track chain. 3,000 miles is the most I’ve ever returned, and that was using a KMC Z1X Inox  SEVEN DAY CYCLIST'S 3000 MILE TEST OF A KMC INOX CHAIN  but it’s a good deal dearer these days, so I’ll stick with the Z510HX.

I took this opportunity to strip and apply some KMC Go wax to the Z510HX and X10 chains, which has also consumed the last remnants of Dynamic Bio Drivetrain Detox, which had lasted considerably longer than I was expecting. I’d spotted two litre bottles of Motoverde Drivetrain Cleaner PRO GREEN MX TRIPLE PACK REVIEW for a very keen price, so indulged.

I’ve found it very effective, although in keeping with the Dynamic Bio Drivetrain Detox it likes several minutes soaking time to make inroads into the lube and contaminant before you get busy with the stiff-bristled brush. There are cheaper formulas around on well-known auction sites. However, they can be somewhat caustic- not what you want on pretty paintwork, seals and other small but significant components.

As for the KMC Go, well, it’s living up to expectations. In common with other waxes, it’s quite runny, requires a surgically clean host drivetrain and several hours (ideally overnight) curing. However, it seems to be holding up convincingly in some very changeable (read wet) conditions, drivetrains are reassuringly clean, silent and shifts silent. The other nice feature is that you can just top up. No need to strip and reapply.   

Elsewhere, I’ve been impressed by the Topeak RX Beam Rack and RX Trunk Bag DXP Topeak RX Trunk Bag DXP and RX Beam Rack | cycling-not-racing. A good option if you weren’t keen on three-, or four-point racks for day rides and weren’t carrying bigger loads. There are better choices, including Carradice’s SQR range-including their Carradry  CARRADICE CARRADRY SQR BAG | cycling-not-racing if you wanted to haul heavier payloads. Though I’ve brought the fleet over to racks, I remain very fond of the SQR system and range of bags. Because they place the centre of gravity higher, handling can take a little time adjusting to, coming from panniers and trunk bags. With conditions turning more spring-like, timely that I’ve reached my conclusions regarding the Castelli Unlimited Bib Tights Castelli Unlimited Bib Tights | cycling-not-racing
