The mystery of the dormant dynamo

 














Once upon a time, dynamos needed voltage regulators to prevent bulb implosion that was a very common issue when tandems and long descents. I was surprised to discover a pronounced lack of illumination from the long serving Exposure Revo lamp. Thankfully,  the Gaciron Cetus 1700 Gaciron Cetus 1700 Underneath Bike Light | cycling-not-racing was playing backing singer. Most dynamos are very reliable these days, but we only need a snagged cable, or some other issue to plunge us into darkness, possibly many miles from home. For these reasons, I typically have a secondary high power rechargeable torch type along for the ride.

The mount remains permanently attached to the bars, the light typically secreted inside a bar bag, or similar bike mounted luggage. Having returned, I pondered the possibilities. The lamp itself, though thirteen years old and exposed to the worst the lanes and trails could throw at it, very well sealed from the elements and had never been subjected to jet washing, or similar abuse.

The cabling also seemed fine. No obvious signs of wear, or damage.  That left the Shutter Precision SL9 hub. The terminal block, spring contact possibly? The hubs themselves are well sealed and turn on cartridge bearings that in my experience, run for 20,000 miles before getting the grumbles.

Before getting deep in the diagnostics, the easiest thing was to switch back to the Shimano Ultegra unit. I’d already decided that I was using the Sl9 wheel as a second/spare so would not get the hub’s electricals repaired, simply run it as a traditional front wheel. Repair would mean stripping the wheel and returning to Shutter Precision in Taiwan.

I’m fond of these units, but I’ve found Shimano are more cost-effective long term. Not least since basic servicing, such as bearing replacement is within the means of home mechanics and decent shops.  The switch coincided with returning from a mucky ride to discover a slow flat caused by a tiny sharp, most likely a hedge clipping.

Tube switched, pin hole patched and a deep, sudsy bucket clean followed. Switching wheels and giving the wheel a good spin, I was relieved to find the Revo lamp coming to life. While the Weldtite All Weather lube Weldtite All Weather Lube | cycling-not-racing was turning a little filmy, it was holding on, so I decided against topping up, not least since the KMC X10 was coming to the end of its life.

Plan was to run the chain out, switch and either apply some more All Weather, or something similar, should it land on the test bench.  Having washed, waxed and dried Denise, I’ve decided to switch to Muffin, since the weather is progressively wetter. Mudguards and a simple drivetrain being the obvious practicalities, although the geometry and stout buxom rubber makes for engaging, yet predictable handling, not to mention a magic carpet ride. Perfect for general riding, these characteristics come into their own during the darker, slippery months.  The M Part Primo Anti Slip Silicone Gel Bar Tape M Part Primo Anti Slip Silicone Gel Bar | cycling-not-racing is still impressing with its damping and reliable all-weather grip. Then of course, I want to get some more miles in with the Sigma Buster1600 and RL150 lights. Steve’s been impressed with its 800lumen sibling Sigma Buster 800 and RL150 Light Set | cycling-not-racing  

Autumn well underway and another year wiser, I’ve decided to drop Muffin’s gearing slightly, no sense straining the knees, or other joints- another Arundel fixed sprocket since these seem accurately machined, well finished and modestly priced. I’ve gone the electroplated, rather than stainless route on the basis of price, although the latter might repay the investment on salty winter roads.  

I’ve been pondering suitable substitution for the Silca Nastro Piloti Silca Nastro Piloti Bar Tape | cycling-not-racing which performs really well on the tarmac and excellent connection with the bars-a good bet for long steady audax miles, possibly winter training too, although in  my view, a bit pricey for the latter. However, given I like to play in the dirt regularly, damping was also a priority.

Enter this Ergon Orthocell. Apparently, it’s made from a medical grade material that’s also employed in their saddles. This is designed to distribute pressure evenly, thus insulate against intrusive vibration, and ultimately fatigue in the hands, arms and shoulders. In common with others, an anti-slip coating to counteract sweaty hands and torrential rains. Whether these qualities also improve grip and control when the temperatures tank, remains to be seen.

Autumnal Promise


 






Not had the cool, bright ambience I’m particularly fond of, rather the rush and rumble of sugar beet being funnelled into trucks and lanes carpeted in a mixture of leaves and acorns, bringing a new dimension to riding. Acorns can prove surprisingly good at testing a tyres traction, especially when the rains strike. No issues with the Maxxis Ravager Maxxis Ravager TR Tyres | cycling-not-racing, Rambler Maxxis Rambler Tubeless Ready Tyres | cycling-not-racing, Vittoria and Continental Pure Contact-plenty of feedback and compliant casings certainly help. The Weldtite All Weather is doing its thing impeccably too. It’s a lower viscosity formula, so a little trickier than some to get a really controlled, sparing coating on the chain. Doing so rewards with much less grit, grot and ultimately need for weekly wipes of the side plates.  Fitting the Zefal Crank Armor presented an ideal opportunity to check chain health-just shy of .5, so a reasonable amount of life remaining. .7 is pension point for 10speed chains, although sometimes, say following a more involved strip, or deep clean and there’s a replacement to hand, I may switch at .6.

There’s no such thing as the wrong weather, rather the wrong clothing- a phrase credited to Alfred Wainright, back in 1973 but it certainly resonates with me, both throughout my riding “career”. Basically, the notion we can enjoy any kind of weather, with the right kit. Admittedly, while I accept punctures and other mid ride mechanicals are “part of the ride”, not to mention product testing but they’re not my favourite experience when it’s raining dogs in the wee small hours. While DWR coatings found on jerseys are great for an unexpected showers and will typically buys 30 minutes to either reach home or don a technical jacket.

The Castelli Do Di Ci to my surprise, forgoes the DWR component in favour of rapid wicking (which it seems to do very effectively) although surprisingly enough, I’ve remained dry in the showery contexts described above. On longer, or potentially changeable outings, I default to Madison Road Race Super Light Men’s Waterproof Softshell Jacket Madison Road Race Jacket | cycling-not-racing since its packable and offers a decent level of protection. Unlike, the classic “condom” jacket, which are great if you want to sweat some weight off, the Madison breathes very effectively and packs nicely into a bigger wedge pack, assuming if like me, you prefer it didn’t consume a jersey pocket.    

Continuing the right kit narrative, packable garments have their place and can be a serious godsend. However, more persistently wet, wintry weather calls for a more traditional technical jacket. A sudden onset of “stormy” weather saw me reaching for this Showers Pass Elements Jacket SHOWERS PASS MEN'S ELEMENTS JACKET | cycling-not-racing which boasts excellent 15000mm waterproofing and breathability, not to mention some very clever retro-reflective technology. The only thing I’ve really missed is a breast pocket for easy access to my compact camera. It also proved an ideal opportunity to don the Sidi Algor, which have held up very well against deep standing water and similarly wet and occasionally gritty stuff. I’ve gone for waterproof socks in the first instance but will also get soe miles in wearing traditional merino blend socks to see how the boot’s water repelling properties hold off the elements.    

 

I was delighted to receive this Altura Night Vision Storm Jacket. The Night vision could arguably be described as something of an iconic model for commuting and general riding. I’ve used previous versions long term and found them very practical and surprisingly durable. Waterproofing and Breathability are 10,000mm apiece, which is my yardstick, for this kind of garment-one that will wick fairly effectively when turning a decent tempo.

That said, I prefer those with a breathability rating closer to 15,000mm for longer, more intensive riding. Weight is another consideration, this Altura tips the scales at just under 500g, which again is typical of this genre of garment but a higher end model, such as this Gore are around the 300g mark, which is quite considerable. Similarly, while models such as the Altura are packable, we’re talking 126-20 litre pannier, or Bike Packing Seat pack such as this PASSPORT CYCLES BIKEPACKING SEAT PACK | cycling-not-racing  or the Lomo 13 Litre Bikepacking Seat Pack  Lomo 13 Litre Bikepacking Seat Pack | cycling-not-racing not rack bag, let alone jersey pocket.

Fine on a tour, but not necessarily ideal on a training run, or day ride. Oh, and if you’ve gone this route (or at the other extreme, returned from a hell and high-water mission) hang the jacket out to dry properly.  Polyester blends are pretty easy to wash too-pop in the machine at 30 degrees, minimal detergent, line dry (or indoors) naturally away from sources of heat.

Booties, Jerseys & Bar Tape

 











Cooler conditions have seen a transition from wax to middleweight wet lubes and more layers. Castelli’s UK importer were generous enough to send the marque’s Do Di Ci Jacket, which promises “unmatched breathability” coupled with a water repellent finish and is designed for temperatures between 5 and 10 degrees.

Following the all-important layering principle, its designed for use with a base layer and on longer outings with a rain jacket to protect against more persistent showers.  Corresponding big longs were also included in the bundle, which is similarly welcome, although ironically the mercury had slid upwards again, to the high teens come midafternoon.

No sooner had I dusted down the Mighty MW7, I was invited to try Sidi Algor MTB Shoes. I’m a big fan of booties for winter-bit of a luxury in some respects but infinitely more convenient than overshoes. Algor is Latin for “Cold”, which is bang on from specification and marketing standpoints.

I’ve opted for a two bolt SPD/Time/Crank Brothers model since they are my default and frankly, the most practical option for the wetter, slippery months.

Available in our monochrome, or black/grey, the Algor feature uppers fashioned from a hybrid of textile and TPU, a triple closure system comprising of a waterproof YKK outer zipper, Velcro® strap and Quicklace Closure System. Primaloft internal lining promises excellent insulation from winter’s chill.  Retro reflective detailing around the heel, piping and heel pull.

 I’m excited and keen to see how they compare with Shimano MW7, which could be rivals, given the price point Shimano MW7 (MW702) Gore Tex MTB Shoes | cycling-not-racing.  At 1048g for the 44, they’re 90g weightier and while the sole is a mix of carbon and nylon the stiffness rating is 5, at the lower end of their stiffness range, so it will be interesting to see how they compare.  

Fresh cleats spun home-with a liberal helping of Zefal Pro II Grease, I’m wondering if sole stiffness might be closer to the Shimano MW501 Shimano MW501 Dry Shield SPD MTB Shoes | cycling-not-racing Reinforcement is apparent around the toe warp bodes well for longevity, while promising some additional protection from stones, stubbed toes and trail debris.  Studs are viable up front, but as with the Sidi Aertis Sidi Aertis MTB Shoes | cycling-not-racing aren’t included in the package, which though not a major thing, is perhaps slightly disappointing, given the asking price.  

Wetter autumnal conditions have meant sudsy bucket washes for Muffin and with it, switching from the Weldtite Wax Weldtite Wax Lube | cycling-not-racing to its All-Weather Stablemate, being mindful to apply it very sparingly. Thankfully, the moderate flowrate makes this very straightforward, and this PTFE free version doesn’t seem so prone to fling. A little too heavy for cleat mechanisms, but fine for cable ends and perfect for adjuster screws, where they enter the frame ends, which can be conduits for trafficking moisture inside frames... 

I wasn’t surprised to discover the no brand crank protectors have disintegrated, so I’ve binned them and replaced with some genuine Zefal Crank Armor ZEFAL CRANK ARMOR | cycling-not-racing, which have lasted over five years without any sign of wear.  An illustration of the old adage buy cheap, buy twice. True, crank arm (or indeed, brake lever protectors) aren’t essential, but they will defend expensive comments from needless accidental damage, especially on a gravel, cross, or mountain bike.

As the temperatures slowly slip downward, the benefits of thermal bottles start becoming particularly apparent. Ok, that’s not strictly so, since thermal bottles have a lot of value during the hotter months, when we want drinks to retain that cold, crisp, dare I say palatable. There’s little merit in tepid tea, or cold coffee. Not the most obvious choice perhaps, but I’ve found traditional Thermos designs surprisingly practical and compatible with standard composite cages.

These are around £25. At the other extreme, there are bike specific models, which promise to keep beverages at their optimal temperature for 12 hours or so and theoretically slot into a standard cage. This Bivo Trio 21oz Insulated Bottle is proving a good fit with standard designs, including these rather nice stainless steel Wolf Tooth Stainless Steel Morse Cages presently adorning Denise’s seat and down tube bosses.

Though generally impressed by the Silca Nastro Piloti Bar Tape Silca Nastro Piloti Bar Tape | cycling-not-racing , I’ve also found some limitations when doing long, steady miles along green lanes and unmade roads. While the grip great, allowing for a more relaxed tenure, it’s a road tape and unless you’re going for gel underlays, I’d steer you towards something thicker. I’m also quietly annoyed I sold a set of On-One Midge drops a few years back, since these are shallow and swoopy for great control sans asphalt. Still, I’ve spent time and effort with stems and other mods, so Denise’s WTB drops are staying.   I’ll leave things here and with Steve’s review of the Magicshine Hori 900 Magicshine Hori 900 Switchable Bicycle L | cycling-not-racing

Longs, Gilets & Other Seasonal Resurrections


 















Autumn progresses, so with the fleet prepped, it was time to bung gilets and other seasonally appropriate riding attire that had been hibernating in various drawers, in the wash.  Base layers, gilets, arm warmers, ¾ lengths…bar tape, cargo nets… Yes, I uncovered the cargo net while hoovering out the garage and investigating some corners.

Cargo nets are really useful for capturing overspill that might not fit into a pannier or rack top bag- particularly useful for awkward items, such as balls, helmet, mangos, melons, clothes, or ensuring provisions don’t escape from an open top basket. Think this one’s a Delta, but Topeak and several other brands produce them. Both net and bar cape emerged pristine from their 30-degree machine wash.  The MW7 bootiesShimano MW7 (MW702) Gore Tex MTB Shoes | cycling-not-racing also got a good scrub, since I’d been a little remiss on this front-beyond testing, not my usual approach to kit.

I’ve switched to Muffin, given the more changeable weather and of course, to play with the Sigma Buster 1600 and the RL150 pairing now the nights are sunrise is slower to arrive. In common with the Magicshine Hori 1300 Magicshine HORI 1300 Front Light | cycling-not-racing , Magicshine Evo 1700 Underneath Mounted Bike Light Magicshine Evo 1700 Underneath Light | cycling-not-racing and the Gaciron Cetus 1700, there are a sensible staircasing of modes, catering for most riding contexts.

I’ve switched Muffin back to the recently re-greased Shimano M540 since they (and indeed, other dual sided designs) are the most practical options for swift re-engagement. That said, the PDES600 Shimano PD ES 600 SPD Pedal | cycling-not-racing and A520 remain good bets, if you wanted a road specific, single-sided design. Packing them with a suitably stiff grease also helps with weighting, meaning it's easier to clip in.  I’m still running Muffin’s Izumi chain on the Weldtite Wax lube, since I’ve not had reason to change and I’m very taken with the cleanliness and low friction. I also tweaked the chain tension very slightly, suggesting some very minor wear. Nothing I was going to get excited by, although chain health is less of an exact science, compared 3/32, so I’ll be keeping a closer eye on things.  

 This brings me nicely to the Zefal Pro II Grease, which seems to be holding out very well against sudsy bucket washes and moving components seem buttery smooth, which bodes particularly well for winter, and I'm pleased to note that to date, it hasn't done anything nasty to seals, or composite components. Again, I’ll reserve judgement until mid-November or so, when the elements have been a bit harsher and possibly to coincide with a bottom bracket upgrade.

Headsets, hubs and bottom brackets benefit from stiff greases and good weather sealing, although in fairness, most seem to solider on very reliably and then unexpectedly get the grumbles. Usually at the least convenient moments!  For context, I’ve had a titanium Hollowtech II pattern and Tiagra do precisely this, same story with the UN55 cartridge type.  

 


One thing I will not be reserving judgement around is the seemingly limitless plastic patriotism and flag shagging engulfing certain sectors of the public consciousness. From an academic perspective, it illustrates how people are so readily mobilised and moulded into false narratives, replicating that which swept Europe during the mid-1930s. From a pragmatic viewpoint, true patriots help within their communities, whether it be painting a community centre, litter picking, helping a neighbour, or helping someone who is struggling. Not for validation, or self-promotion, but because they genuinely care about others, seek to build people up, and bring them along.
