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

Torqued & Lubed


 





I’d reached conclusions on some tooling and lubes, specifically the Feedback Sports Torque wrench and NZero dry wax lube Nzero Dry Wax Lubricant | cycling-not-racing (sevendaycyclist.com). I’ve been really impressed with the standard of engineering and user-friendliness of the torque wrench. Torque function aside, size and ratchet function mean it’s also delightful to wield in awkward, or confined spaces- bottle cages being prime example.  

 

The ability to use it as a T-wrench for added leverage on stubborn fasteners is another definite plus. Cost aside, the only detraction is the preset 5nm setting. Fine for a lot of components. However, equally too low and a little high for other components, including seat collars, stem bolts, bottle, and mudguard/carrier fasteners. 

  

I should also point out that traditional torque wrenches should not be used to undo parts. Doing so will damage the mechanism. The NZero wax, though less tenacious than some is still relatively durable and cures much quicker than a lot of wax-type formulas. The Momum MIC Wax Momum MIC Wax Lube | cycling-not-racing (sevendaycyclist.com) cures a little faster and has, during the summer months returned over 400 miles from a single application. 

  

However, it’s a semi synthetic blend, while the NZero uses natural ingredients. Unlike some waxes, the NZero doesn’t melt messily in high-temperatures and transfer to hands is minimal. A definite plus, should you succumb to a flat, or commute in smart trousers.  

 

Staying with punctures a moment, I’ve also become very endeared to the AS2 Pro Max- basically a refined, pocket-sized compressor that will raise around 4 tyres from a full charge. I’d still be inclined to carry a mini pump and possibly a Co2 setup on a long, or multi-day ride but for general, day-to-day training I’ve found it infinitely preferable to the alternatives. The important thing is to charge it regularly. 

  

Assuming it’s just been sat in your chosen bike luggage, pop it out and charge weekly, otherwise, at the earliest opportunity. Bargain on an hour or so, from the mains. It's possible to charge it from the USB charger on some dynamos, including the mighty and much revered K-Lite K LITE BIKEPACKER ULTRA DYNAMO LIGHT | cycling-not-racing (sevendaycyclist.com) systems, which might be fine on tour, but again, I’d be carrying a mini, or possibly frame-fit pump as backup.  

 

In common with the Fumpa FUMPA PUMP | cycling-not-racing (sevendaycyclist.com) it’ll manage higher pressures 120psi a time, which caters for most contexts. However, it is decidedly loud, so stick with the track pump at home, at least during unsocial hours.  

 

200 charge cycles before the lithium-ion battery will experience a 10% loss in capacity, which suggests a decent working life and besides, provided you ensure I-ion batteries don’t fall below 70% charge wherever possible, you will considerably extend their lifespan. Talking of pumps, here’s Steve’s review of the Silca Impero Ultimate 2.0 Frame Pump Silca Impero Ultimate 2.0 Frame Pump | cycling-not-racing (sevendaycyclist.com) 

 

I was surprised to experience some tingling in my right hand wearing the Grip Grab mitts- it's an isolated experience thankfully and has me wondering what induced it. I hadn’t changed any contact points.  

 

Lights are useful year-round. I ensure there’s at least set of blinkies fitted to the Holdsworth and Teenage Dream, should conditions unexpectedly change, or I lose track of time, while making the most of late summer evenings. Fixed, Denise and Ursula all sport dynamos –high power lighting and on tap. Magicshine has graciously sent me some of their new range, which caught my attention. Some I cannot discuss now  

 

I’ve received their evo 1700 underneath mounted bike light, which as the name implies sits beneath the bars, giving a clean aesthetic, while crucially combining a highly effective mix of flood and spot beams. The former ensures a good peripheral sweep of light, the spot picks out the details, lens technology projecting both intelligently, to minimise risk of dazzling or similar nuisance to other road users.   

 

The integral battery is another appealing feature. In common with most modern high-power lights, there’s a wide spectrum of output from 200 to 1700 lumens, in theory catering for most contexts., although formative impressions suggest the beam pattern is road centric.  

 

Again, run times at the higher end are relatively short, so this genre is ideally suited to those who train or commute in varying conditions and enjoy the odd blast along the backroads at warp speed. There’s a remote control for added convenience and though relatively standard these days, you can tune to taste using the brands’ app.  

 

In common with other vehicles, there’s a high and low beam, designed so you don’t dazzle oncoming road users. Thankfully, this can be controlled with a deft prod of the remote, although as with any system, worth doing a few practice runs, so this action becomes intuitive before heading out.
