Snapped Springs & More Saddle Swapping





Wet, gritty stuff not only consumes chains and other drivetrain components but brake seals and springs too, it seems. Having exited a junction, my relative serenity was interrupted by a strange binding noise. I initially believed it was this BTwin Triban shoe slipping off the Wellgo’s surface, causing my heel to nudge the mudguard out of alignment.  

The chainstay bridge bolt needed nipping tight but there was an unusual amount of slop in the rear brake. I predominantly use the front but nonetheless, the rear needs to be bang-on. Given I was by the roadside, seven miles from home, on a very dark and rainy night, I centered the Avid Shorty 4 and made a mental note to strip and inspect once I’d returned.  

Univega on my long-serving aluminium alloy work stand, I stripped the Avid and discovered the spring had sheared clean in two. Claimed by fatigue but slightly odd, given it didn’t lead a particularly hard life. Presented and opportunity to re-grease the bosses and mounting hardware.  

A nice stiff grease-Park PPL1 https://www.sevendaycyclist.com/park-tools-polylube-1000   being the obvious choice, since it was already loaded into my gun.  The Genetic CX cantilevers, were an obvious substitute.https://www.sevendaycyclist.com/genetic-cx-cantilever-brakes However, small frames, wide arm cantilevers and size 43/44 feet are a recipe for heel clearance hassles.  

Therefore, I opted for these Shimano CX50. A relatively low- profile model designed to work with Super SLR levers, hence no compatibility (cable pull) hassles with road brifters. Set up is relatively straightforward too and I was able to utilise the existing straddle wire. Rather than Shimano’s Y pattern.  

I’ve also been contemplating a new ring-at the right price. 94BCD is starting to become the preserve of retro pricing these days and choice is similarly, restrictive. Therefore, replacements can be very cheap, or very steep. Research suggests a 36 tooth is as close as I’ll get.  

Though adequate, I’d welcome a slightly lower, closer spread of gears, while still enjoying a 1x10’s simplicity. Much of this has been prompted by persistently high winds. Conditions that have defined the past few months, here in the UK.  

I have also been pleasantly surprised by the stoicism of the Juice Lubes Frame Juice. It does attract some grimy patina but this gets locked into the top layer, meaning you simply dismiss this, using a soft, lint-free cloth.  

An invisible, protective barrier remains and has done so for several weeks before replenishment’s been necessary. One minor consideration is that its designed for gloss finishes, so something like Naked Bikes Bike Bling https://www.sevendaycyclist.com/naked-bikes-bike-bling might probe a more cost-effective option if you have a bike or fleet with gloss/satin and matt surfaces.      

Now, no sooner had I played musical saddles; this rather fetching Cycles Berthoud Soulor leather saddle arrived at my door. Measuring 278x146mm and tipping the scales at 423g, its actually 40 odd grams lighter than this titanium railed SPA cycles Aire. One that served on my fixed gear winter trainer, for a good few thousand miles.  

The Aire is made from Australian cowhide, which tends to be thicker and subsequently, took longer to break in. Even with periodic deployment of Proofide/similar leather “food” it took 500 miles before the Aire was moulding to my derriere. 

Putting this into context, a modern Brooks is 250 miles, give, or take. The solour’s rails are a highly polished stainless steel (although there are titanium siblings, if you can stretch to £189) which adds some compliant zing. Unlike electroplating, there’s little risk of them tarnishing, although stainless steels are alloys of different metals. Therefore, a quick buffing and occasional hard-paste waxing never goes amiss.   

In common with the Spa cycles Aire, the underside appears to have been treated, offering it greater protection from the elements. A lesser consideration with full length mudguard perhaps but again, another consideration when buying traditional leather saddles.  

Thus far, ours feels more like a Brooks Swift. Quite firm but not unforgiving. Even so, bedding in has been a very gradual process, starting with as few 25mile loops, before increasing the mileage by ten miles each time, giving the top side periodic helpings of a water-based hide food, to assist this assimilation to my ass.  

Although the evenings are getting steadily lighter and seemingly less wintry, good lighting remains a must. I love the convenience of dynamo systems-at least up front.  Though failures are pretty rare these days, I always run these in conjunction with a compact, commuter type light up front and two rear lights. Aside from presence, so long as good charging discipline’s maintained should one fail, there’s another to get home with.  

Again, being someone who predominantly tackles unlit roads, 15-20 lumens is my minimum-even for a secondary/contingency unit. Up front, even with the dynamo, I tend to go for a 500lumen light, defaulting to flashing (100-150 lumens). However, a steady 250/400/500 lumen mode is really useful for tackling punctures and similar roadside mechanicals-especially if you can mount it atop a helmet, leaving both hands free to do the fixing.  

These Moon Meteor and ETC Sirrah Front/Rear Light have proven particularly good defaults. I’ve also been pleasantly surprised by the Oxford Products Ultratorch R75 rear Light https://www.sevendaycyclist.com/oxford-ultratorch-r75-rear-light  . Its bright, with sensible staircasing, although run times are relatively modest and favour commuting/winter training, rather than longer distance/endurance events.

Lighter Moments







Unnerving creaking from my Univega’s post region prompted a swift dismount but turned out to be little more than a loosening cradle bolt. Easily silenced with a lick of grease and nipped tight with a 4mm Allen key. 100miles in and the wonder metals’ unique, subtle zing adds to the machine’s already compliant ride, saving a few grams over a 6061 model too.

Another box of goodies arrived on my doorstep this week, hence, this Bontrager flare R city tail light clings limpet fashion below the increasingly indispensible Cycliq fly 6 https://www.sevendaycyclist.com/cycliq-fly-6-camera-and-rear-light

This little blinkey boasts a total of 35 lumens and has daylight and two night time flashing settings. “Intelligent” systems that automatically kick down once battery reserves plateau is pretty commonplace these days but sensors that adjust the beam’s intensity according to lighting conditions are also becoming mainstream.

For such a small light, visibility is pretty impressive- reckoned to be around the 400 metre mark. 

My own experience suggests this is likely to be on open roads and clear nights. So far, I’ve only been running it during daylight hours but have been pleasantly surprised by its potency. The positive top-mounted switch is easily commanded in full-finger gloves and its dimensions are perfect for pared to the essentials road and TT builds.   

I wouldn’t want to be following at close quarters in the flashing setting, say on a group ride and I generally prefer models with greater surface area for town work but let’s see what the coming weeks and different riding contexts reveal.

Up front comes this Cygolite dash 450, which as its name implies is a compact 450 lumen model, very much of the commuter plus genre i.e. capable of delivering enough bite for semi-rural navigational work on the one hand but with a wide range of town-friendly settings.

Years spent riding trails and back roads in the dead of night have meant a definite leaning towards big guns that belt out 1000 lumens plus. That said I’ve become increasingly partial to these and similarly unobtrusive designs that have enough wallop for those spring/summer evenings when that hour’s blast on the best bike has transitioned into two.

True, most blinkies in flashing modes usually provide enough presence in the seen-by sense and for contingencies but I prefer a proper light, something around the 350lumen mark running alongside in these contexts.  

The Cygolite boasts 7 settings, four night modes and three for daylight, which should cater for most contexts, save for dead of night and quoted run times between 1hr 15 and 70hrs. Build quality is pretty solid throughout at the bracket allows some adjustment, which is a boon when affixing to moustache bars and others, with less useable real-estate. 

This sample has been playing backing singer to my Univega’s Exposure Revo dynamo system, which for my purposes and the machines four seasons’ hell n’ high water design brief is indispensible.

Back to the Cygolite; the rubbery centre mounted switch cum battery life indicator is ideally positioned and easy to use in middle-weight gloves and on the fly. The top row of 4 LEDS has a slightly dated feel on the one hand given the increasing ubiquity of COB technology.

However, the combo works on the basis (one that I happen to subscribe to) that in most riding contexts, drivers tend to notice a pulsing/flashing set up first. Formative impressions are quite favourable when run in overcast daylight.

Experience with this genre suggests these are fine for longer commutes/rides with a mixture of city/suburban and shorter semi rural sections. Again, several weeks in different contexts may reinforce, or refute this opinion...

Staying with lighting, I’ve always been drawn to integrated systems, higher end hub gearing and dynamos in particular, especially for touring and four seasons’ working bikes.

Giant has extended this principle to its Strive helmet. I’ve always been impressed with Giant’s level of specification, not to mention their TCR concept, which arguably normalised semi/compact geometry road bikes back in the late 90s. Look closely and you’ll notice there’s a branded fascia that pops away to reveal a magnetic plate. This is specifically designed with their Numen Plus Link tail light in mind.

The NPL is a four mode, 20lumen model with a quoted 5 hour run time in its lowest setting. It uses COB (Chips on Board) technology, where diodes are mounted directly aboard the circuit board, saving production time and optimising output.
Another neat feature is the auto on/off sensor that works in the same way as a Shimano dynamo switch, reacting to the light levels and automatically turning the light on/off.

20 lumens sounds tame given the lumens race but given it’s positioning, anything more potent is likely to dazzle and alienate approaching traffic. All things being equal and save for really foggy contexts 15-35lumens are sufficiently potent for most conditions and from a generous distance too.
The NPL charges via magnetic USB system, reminiscent of one Blackburn employed on their flea a few years back, although much easier. Connect light to base via the magnets and the plug the USB cable into the mains/PC/Laptop port.  Talking of laptops, time I gave mine some down time and headed out to test some more goodies.
