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.

Freeze frame









 So, temperatures tanked again. Not an issue for me, since I’d left the Schwalbe Marathon Winter/Plus After The Gritters Went Home | Seven Day Cyclist/TESTED: SCHWALBE WINTER SPIKED TYRES (sevendaycyclist.com) in situ and carried on hustling along the lanes at a steady 17mph, Ursula never missing a beat, handling as if on rails and allowing me just to relax and enjoy the ride. I will occasionally tweak the specification, say when parts wear out, or in the case of tyres, to suit seasonal changes/conditions. Once this icy spell passes I’d quite like to go the Schwalbe Billy Bonkers route...  

While the Schwalbe winter/Plus tread pattern is designed to sweep snow away (whereupon the tungsten carbide spikes bite into the impacted ice beneath) but it’s also very capable on greasy, impacted mud, forest trails and bridlepath.  Days are getting slightly longer but it’s still predominantly dark, another good reason for prioritising reliability over outright zing. It’s also great for testing lights.  


Bob Elliot &Co Bob Elliot Co Ltd - Suppliers of high quality bicycle supplies to registered traders (bob-elliot.co.uk) have sent me these two Ravemen units. The CLO5 and CLO6. These employ sensors that are apparently unique to them. Rather than increasing the light progressively as dusk creeps in, it senses approaching vehicles and produces a warning flash, so theoretically reinforcing rider presence.  There is also the option of switching this function off, say during daylight (which it isn’t intended for).  


The CLO5 pumps out a maximum of 30 lumens, the CLO6 50. With a few notable exceptions, the lumens race seems to have tapered off a little in recent years. Several months down the line, I still love the Magicshine See Mee family, particularly the 200 and 100 models.  


As I’ve said elsewhere, the 200 and 100 refers to lumens in “braking” mode, rather than output per se. The 200 pumps out 30, 70 and 140 lumens, the 100 18.36, and 72lumens. A good range that caters for most riding contexts. My yardstick for town/suburbs is 10-15 lumens, 30odd for unlit backroads. However, optics also play a big part.  


The advances in lens and diode technology means even relatively low numbers are still quite useable.  Lezyne stick drive rear light being a primer example. It pumps out a maximum of 30lumens, staircasing down to 4, which is genuinely quite useable around town. Its 12lumen flash 3 option covers most other bases, as a default.  


Admittedly, I still prefer something more retina tickling for regular saunters along dark, mysterious lanes. Professional/commercial contexts aside, I’m someone preferring to be under the radar but riding at night, I like being as conspicuous as possible.  

Staying on the topic of lenses, I received this Sony HX60 compact camera. I like carrying a compact camera on rides, means I can capture things, record significant points regarding product performance, etc. It replaces another little Sony that developed a stabiliser/lens fault-beyond economic repair, after three years.   


Image quality is good, especially by compact standards, thanks to the sensor size and manual control, although it only shoots JPEG, not RAW. Measuring 110x64x40mm and weighing around 200g, its quite substantial, but still fits inside a breast/nelson type pocket, so meets my requirements nicely.  It also captured another, unexpected side benefit of the wider, trailer hitch skewer.     Talking of compact, here’s Richard Peace’s review of the Cube Compact Hybrid e-bike CUBE COMPACT HYBRID | cycling-not-racing (sevendaycyclist.com) 


Y wrenches are another lasting favourite tool of mine. I have a 6, 8 and 10mm socket version bought for a few pounds, thirty years back. Super-convenient, I’ve just acquired a 4,5 and 6mm Allen key version.  


Ergonomics mean it’s more convenient than a fully loaded multi-tool, especially tackling Aheadset, seat collar and, cable pinch bolts etc. Ergonomics are another consideration when it comes to brushes, a nice, efficient design means keeping bikes and their drivetrains, less of a chore. Zefal ZB Multi Brush ZEFAL ZB MULTI-BRUSH | cycling-not-racing (sevendaycyclist.com) has some nice features and decent, knuckle-sparing length.
