Filth=Fixed FGG


 




 


Winter sees me alternate between Ursula and my beloved fixed gear winter/trainer. Both have been with me for 26 and 19 years, respectively. Ursula wears the spikes when it's plunging below zero, or when I’m fancying exploring some trails beyond the beaten path. The fixed is frisky, fun and the simple transmission fares much better in winter’s slurry. The cyclo cross geometry means its nimble and fun but not skittish 

I wouldn’t ride a track bike, even if drilled for a front brake as a winter mount due to inappropriate geometry, lack of clearance for mudguards and more importantly wider section rubber. This is the V2, with 120mm track spacing, the MK1 was markedly similar, save for 135mm spacing. 120mm means any track type hub slots straight in without any considerations, or mods 

The 135mm version allowed hub gears, or indeed, single speed mountain bike hubs. There’s a lot to be said in favour of both (indeed, On One returned with an evolution called the Pompetamine designed to be run with discs and hub gearing). I toyed with one before getting Denise, although would’ve gone for a lighter (carbon) fork.   

I had been browsing the Condor website and was looking at framesets. The heyday of fixed's popularity was 15 years ago, which means frames have become less ubiquitous, but this also has a knock-on effect pricewise. Spa Cycles Audax Mono is probably the most practical, contemporary off the peg framesets for general road duties.  

It features Reynolds 725 tubes, rear facing ends, carbon forks, mudguard and four-point carrier mounts and drillings for dual pivot brake callipers. Kona's Paddy Wagon, albeit the earlier models 2006/7 being my preference Kona Paddy Wagon 06 review | BikeRadar Deda Cro-moly frameset, two sets of bottle mounts, guard and carrier mounts, clearance for 700x28c-32mm if you were prepared to forgo mudguards.   

Pearson Touche. Ridgeback Solo World and Dawes Mono were all good off the peg, complete build options from a few years back. Reynolds 520 might not set pulses ablaze, but it's a decent Cro-moly that's well suited to workhorse duties without having a lumbering tank-like ride quality.    

I’m presently running 28mm Schwalbe one365 at the rear, a 30mm WTB Exposure up front WTB Exposure Road Tubeless Tyre | cycling-not-racing  both are engaging yet still handle very well in wet, slippery conditions and the ability to slow by holding back gently against the cranks, rather than applying the brake ups the control in situations where engaging a brake might result in going rubber up.  

Saddle Back also sent me this Feedback Sports Compact Fixed Torque Driver, which is a tiny, pocket-sized torque wrench fixed to 5nm comprising of 4,5, 6 and T25 bits, which fit beautifully into the composite driver handle. Being ¼ inch design, it's also compatible with a wealth of other sizes, so can be built up to suit your needs, which is another definite plus. There's an extension pole, for those contexts where you might need a little more leverage. Bits are fashioned from S2 steel, the torque driver is reckoned fully accurate to +/4 for up to 3,000 cycles and the limited lifetime warrantee inspires further confidence.  Suffice to say it's unobtrusive enough and accompanying me on pretty much every ride   

 

I've primarily stuck to riding the fixed, since winter's slush and slurry is all consuming and the simple drivetrain keeps things simple and economic. There's also the more direct sense of connection. This has been said to the point where it's become cliche' and arguably meaningless. However, there's a sense in which you must predict changes in gradient, bends and other factors more readily than a geared configuration, which is more forgiving of misjudgement. In this regard, the ride and that union between rider and machine becomes closer, more direct. Not that I'd want to go everywhere on a fixed, rather it's a configuration I'm very fond of. 

The only thing to keep in check is the chain tension- too tight equals noisy and inefficient coupled with more rapid drivetrain wear. Too slack and it’ll run the risk of jumping off and jamming-usually at the least convenient moment. Chain tugs are a definite help here. I’ve had to switch from the Genetic to a discrete but seemingly effective pair (bought on Ali Express a year, or two back) since they were impeding the Topeak Uni rack’s hardware.  I didn’t want to stress the screws, or worse still, the frame’s eyelet threads.   

This also proved an ideal opportunity (read no excuse) to give the bike a well-deserved wash n’ wax clean-purging grit and gloop, while leaving a protective wax layer behind. During winter, at least when the gritting lorries have been out in force, it's best to give bikes a cold-water rinse first. Hot will simply accelerate the caustic process.  

Just organic muck in this instance, hence a quick blast of higher strength, custom mixed bike wash to dissolve the ingrained grot, while I’m filling those buckets.   Since we’re here, a lot of people think high foam (though visually convincing) is the most effective. However, formulas that cling to the host surfaces are more effective and get my vote every time. I've switched to Peaty's Link Lube Premium, since I was running low on the Wolf ToothWolf Tooth WT-1 All Conditions Chain Lub | cycling-not-racing

I’d also had this PDW (Portland Design Works) Radbot rear light expire- seems to be a corroded switch-I've tried flushing it through with water displacer but to no avail. I also had the back expire on another long-term favourite-Topeak Redlite Mega. I’ve got busy with the superglue and left that curing overnight, so hoping that sorts it, even for the short term, while I hunt down a replacement.    

I find there's a temptation to sleepwalk into the New Year, so prefer to keep structure and busy, albeit at a more moderate pace, enjoying the sense of peace and calm, but drawing parallels with riding fixed, maintaining momentum.

Critical Thinking & The Sentimental Season


 





Why aren't you at work??? Well, I am at work thank you very much. I work 70hours per week, just a very different schedule to some. Cycling journalism and product testing are not my only professions, but ones I am particularly passionate about. I wrote my first magazine feature for a national cycling title, aged 14, back in 1988- a test of a Muddy Fox Courier Mountain bike.  

I am highly experienced in several riding genres, but don’t profess to be expert, let alone an oracle. Those that genuinely are, carry themselves with a matter-of-fact humility. There is always something new to learn, concepts to understand, even if not necessarily embraced. I am similarly passionate about photography-models, street and industrial, specificallyModels & Portraiture - Stenning Photographic Model & Portraiture Photography Continuous development and lifelong learning are imperative, otherwise stagnation and regression set in. 

Back to 1989 and I bought my first track pump to counter frequent punctures, tyre wear and loss of wheel truth courtesy of under inflated tyres. Workshop pumps are one of those investments that will repay their investment countless times, even the budget models. The track pump in question was an orange Silca, capable of delivering 200psi- not that I’d ever needed that-120psi was pretty much my ceiling and it was best suited to road biased rubber 

Sure, I’d raise a pancake flat 26x1.95 to 50psi and faster than mini/hand pumps of that era. However, best for high pressure, rather than high volume. Mine came with me to London and was eventually gifted to my favourite bike dealer when I bought an upgraded replacement in the autumn of 1998.  

I wanted to give it a loving home, albeit as a second/workshop spare. Having learned of my fondness, some might say nostalgia, their UK importer sent me this beautiful, contemporary Silca Terra- £139 at full rrp and a thing of beauty, from the hand lathed ash (wood) handle with hose-guide, and 76mm (3 inch) gauge 

Unlike my original Silca, the barrel and handle are made from aluminium. There’s a reversable Presta/Schrader valve chuck with a bleed button in case you’ve got a bit carried away. Once upon a time, track pump gauges were notorious for having passing affinity with reality, now (particularly with digital gauges) things are within 1psi or so. I’ll be cross referencing that with my standalone digital gauges. Silca claim the Terra’s analogue unit is precise to within.5 psi at the lower end of the 30-120psi range. This covers most bases with contemporary bikes and tyres. I’ve raised a 26x2.3 tyre from zero to 60psi in 64 strokes.

However, some folks needing higher pressure, will need to look elsewhere. Saddleback also sent me this Feedback Sports Reflex Fixed Torque Bit Driver. It’s designed to be brought along for mid ride rescue, not workshop duties, no bad thing-horses for courses- I wouldn’t want to be lugging a workshop torque wrench in my bike luggage. It is based around the standard ¼" driver, meaning bits are easily acquired, or brought along, meaning you’ve got a custom toolkit for the road.    

Stock, we’ve got 4,5, 6mm and Torx T25 bits, 1 steel 5Nm torque extension. The driver body is a hybrid nylon/steel and the whole kit comes with a limited lifetime warrantee. I’m told the torque is accurate to within +/- 4% for up to 3,000 cycles.  


I was surprised that it took this long for Ursula’s rear mech cable to stretch and shifting go decidedly “off. Just a matter of slackening the cable, pulling through and snugging down, although I always ensure I’ve a few spares handy before tackling these jobs just in case the inner wire in question decided it was going to implode. This is particularly significant at Christmas, where it’s bound to happen when you’re out of spares and the bike shop’s shut...  

Oh, and that’s the reason you get everything prepped and adjusted before heading out on a tour, reliability ride, or similar endurance event. While checking the fixed’s rack hardware, I found the otherwise superb Genetic chain tugs were impeding the fasteners. Not wanting to stress the fasteners or damage the eyelets I switched to a very discrete set bought as curiosities on Ali Express a year or so back. Solved the issue and hopefully they’ll do a decent enough job of holding chain tension.  

I’d been sent this Beam Corkey Premium Review Mirror a few weeks back and had my curiosity spiked when I saw a homage on one of the auction sites, or rather, the site bots brought it to my attention (along with 1500 inflatable pleasure dolls). “The W’EST Biking” version is breathtakingly similar, albeit noticeably heavier, refuting suggestions of “badge engineering”. I’ll close here with Steve’s review of the Ravemen FR300https://www.sevendaycyclist.com/ravemen-fr300-daytime-running-light
