New Guards & Big Flaps


Ended up stripping the Univega of the mighty Tortec chrome plastics, while I waited for these superbly solid SKS BLUEMELS SHINY 26″ 60 BLACK SET to arrive. Good thing I did too, since the front was one rattle away from falling atop the tyre, and launching me over the bars.

Sans guards it has a very rugged, raw simplicity. Arguably closest to the original 80's concept that fired my teenage imagination, its trail potential was fully realised, along with some seriously big grins for a few evenings. 

The first was quite cold, frosty, although rains returned the following two nights. Thankfully I've been testing these Funkier Aqua Water Repellent Tights. Very welcome (Competent too, especially considering the asking price (£74). 

Talking of the 80's, though frame fit pumps have largely disappeared (thanks in no small part to compact geometry framesets, and mountain biking's other influences) Zefal HPX High Pressure Frame Pump remains quite relevant. https://www.sevendaycyclist.com/zefal-hpx-frame-pump 
I returned from Tuesday night's mud spattered meander to find the SKS guards waiting. 

Not the sort of job I wanted to embark on, then. Wednesday morning came and I wasted no time in un-boxing and weighing the guards, which are 50g lighter than the Tortec. 
Next my beloved tubby tourer was popped in the workstand, stripped of wheels and given a rich, sudsy bucket wash. 

Rinsed and dried, I turned my attentions to the front guard. Fitting mudguards can prove fiddly, rather than difficult. In this instance, it's complicated by my preference- a Gusset Uni Head system, rather than the Star Frangled Nut (SFN). 

Now, these might carry a weight penalty over the humble SFN, or expandable wedge type systems. However, they offer improved security. I've never had one work loose and they're also reckoned to keep things together, in the event of a steerer crisis. One of many experiences I would like to keep academic. 

However, it does preclude attaching mudguards via the fork drilling. I judiciously cut out the riveted stainless steel mount, using a hot blade. Given the quality of chrome plastics, and valuing my own digits, this had to be done in three stages. 

Having established the uni-head's bottom nut would slide snugly through the hole, I began bolting the guards in situ. Measure twice cut once when tackling the stays but otherwise everything bolted together smoothly, sans faff.

Achieving graceful, flowing lines is very simple with this calibre of mudguard too. 90, rattle free miles in, and despite the absence of mudflaps coverage is surprisingly good. Nonetheless, presented with a scrap Panaracer tyre, I decided to cut and fashion a set. 

Arguably pop-riveting would've been the neatest method but I settled on a high-strength glue, left clamped and curing for 24 hours. Though not a precision cut, they're neat enough and I've been refining things, gently sanding excess glue-at least where it can be seen. Besides, blasted with dodgy looking water, diarrhoea like mud and other greasy midwinter muck, they'll blend in nicely!  

Talking of which, the Weldtite TF2 Performance all weather lubricant https://www.sevendaycyclist.com/weldtite-tf2-performance-all-weather has fared much better than the Juice Lube Ceramic Juice Chain Lube in comparable conditions. 

The Ceramic Juice hit 185 before the dreaded squeak struck but I should point out, its actually blended for dry to moist, rather than wet weather. 

Therefore, I will reserve judgement and resume testing once (some might say, if) we get a decent dry spell. Meantime, I've switched to their Viking Juice, which they say, is the most durable of their range. 

Application is reminiscent of early ceramic blends in the sense its applied in stages. Whereas some required you to ride around, before adding a final layer, Viking Juice takes but a few minutes. 
Between 2 and 4 coats are recommended, so having established we're in the depths of winter, I've gone the whole hog. 

Its a really runny formula too, designed to seep deep within the chain, so keep some clean rag handy and resist any urges to apply indoors. My Univega's drive train feels suitably frisky but staying prowess is another thing entirely. 

Been rather impressed by their JL69 Bike Maintenance Spray, which seems versatile, durable and very competitively priced. Cleat/mechanisms, locks, cables and jockey wheels have all cheered up with a squirt. Electroplated Allen bolts and similar fasteners have also remained taint free.  

Been rather impressed by this Naked Bikes Pro Wax Special Edition, too. https://www.sevendaycyclist.com/naked-bikes-pro-wax-special-edition  . Though hardly cheap, the quality and durability of finish is very impressive. A Christmas gift idea, for the rider who is tricky to buy for.

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.

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.
