Blink & You’ll Miss It






 
Been a few weeks since my last entry. A welcome tsunami of products has kept me out along the lanes, late at night and mischief moderated. 500 miles in, I reached some very tangible conclusions about Vee Tire Co Zilent MK2. https://www.sevendaycyclist.com/vee-tire-co-zilent-mark-2-tyres
Our 38mm sections have proven themselves swift, comfortable and extremely durable rubber, for everyday riding. Project Dawes has also gathered a little more momentum https://www.sevendaycyclist.com/gravel-on-a-budget-part-two-compone  and the Weldtite TF2 Advanced Ceramic chain wax has also performed, pretty much as I was expecting, right down to the miles per application. https://www.sevendaycyclist.com/tf2-1  For the time being, I’ll stick with its clean and slick characteristics, while conditions remain distinctly fair-weather.
Will be interesting to see how it fares, during the darker months. On balance, I prefer a cleaner lubricant that requires more frequent reapplication, over something sticky and sludgy. However, chances are, by this point, I’ll have switched to something more stoical.
With trees shedding leaves, the nights are closing in. Dusk chimes around 18.45 and its nigh on pitch black by 19.15. https://stenningphotographic.blogspot.com/2018/10/on-waterfrontwith-aurora-ray.html
My MK1 KA’s creaking Constant Velocity joint and dental appointment meant I wasn’t attending the Cycle Show, at Birmingham NEC’s. However, Steve (co-editor) was and suppliers are increasingly keen to work with us.
This week I received these lights from Oxford Products.
We have their UGOE Classical 1000 lumen mini, which is a four-mode light, producing maximum output of 1000lumens. Pretty much my “on paper” benchmark, for speedwork along unlit lanes. 
There’s a lot to be said for the latest generation of high- power slimline torch types. Blackburn’s Dayblazer family (1100, 800 and 400 lumens respectively) being prime examples.
No cabling, or external battery clinging to the top tube… Output to run time ratios are relatively favourable. So long as you are using the most powerful settings sparingly.
Longer distances, along pitch black roads, (where navigational prowess is king) calls for a bigger/replacement battery. Now, better quality systems have become much smaller. This Xeccon 1300 being a case in point, although the neoprene encased battery is still pretty brick like https://www.sevendaycyclist.com/xeccon-1300-wireless-front-light .
 The average auction site “Master Blaster” is relatively large, in every respect, consuming a fair chunk of handlebar real-estate. Yes, they may pump out 1500 lumens-more in some cases. However, low-rent lens and reflector mean output quality is a little sketchy. Most notably when haring along swooping descents. A decent spot beam makes potential hazards so much easier to spot, and ultimately, swerve.   
Looking through the online catalogue, I wasn’t expecting the Ugoe to be this diminutive. As the photos illustrate, its CNC machined aircraft grade aluminium lamp and switch are literally thimble sized. Ample room for computers, GPS, action cameras/similar creature comforts.
Tidy freaks will want to route the cabling more discretely along the top tube. There’s plenty of it too. Ample for helmet mounting (courtesy of the supplied Go-Pro design).
Even the 3.7volt 5200mAH lithium ion battery is slimline and fits very unobtrusively, in a jacket, or jersey pocket. There are four modes, 1000lumens is reckoned good for 2hrs 30 minutes, 500 lumens 5 hours and 10 hours claimed for low and flashing, respectively.  
Looking forward to seeing how it compares, output wise, with compact torches, such as this Blackburn Dayblazer 1100.
At the other end of the lighting spectrum we have their Ultra Torch R50 and Ultra Torch F100. 50 and 100 lumens apiece, both are at the more potent end of the blinkie market. 
Arguably you only need two, but eight modes, 270-degree projection and run times between 2 and 45 hours are very appealing. Some obvious nods in the direction of Cat Eye Rapid X.
Physical profiles aside both use COB (Chips on board) technology (where diodes are mounted directly on the circuit board). this ensures more can be shoe-horned into the same space, generating greater intensity.
The Ultratorch are fuelled by a 3.7volt 500mAh Lithium Polymer cell. A rubberised “foot” hides the micro USB port, keeping rain and other wet ingress outside. This also ensures the light sits flush, against seat posts and indeed, seat stays
Good optics and intelligent deployment are more useable than lumens alone. For example, by my reckoning 15 lumens is about right for town duties. Strikes the right balance between asserting presence, without tickling retinas at close quarters, or consuming reserves overly quickly.
30 is still OK but better along the open road. On pitch black roads, misty mornings, or as a daylight mode, 50 is good. Distinctive strobing patterns also play a very significant part too. £17.99 apiece, they seem seriously good value, but lets’ see what the next few weeks reveal.

Roads Paved With Dung











Shod with the Schwalbe Marathon GT, Cross flavoured fixer and I have been belting along the back roads. The GT feel a lot faster than their 808g suggest and continue to inspire confidence by the bucket load-in every sense. Talking of tyres, Seven Day Cyclist has an eight month test of another beefy section tyre, Maxxis Roamer http://www.sevendaycyclist.com/maxxis-roamer-tyres  

Fun is obviously high on any rider’s agenda but for me at least, reliability is level-pegging on a daily driver or winter/trainer. I want to concentrate on the ride, or let my mind wander in reflective/creative directions. While punctures and mid-ride mechanicals per se, are all part of riding, being sat by the roadside tackling a flat; or broken chain are events I prefer to keep infrequent.

Last Thursday, the thermometer had barely crept above minus 2, so I headed out late afternoon. Run at 85psi, their contact with the surface, coupled with the ability to regulate speed by holding off against the cranks, made 1in 4 descents and similar efforts that bit more comfortable.

Ascending one climb, dancing on the pedals and shoulders shuffling to similar tempo, my heart momentarily sank at a fut-fut sound, synonymous with a flaccid tyre. Glancing over my right shoulder, I was relieved (and somewhat amused) to discover this was a wheezy, asthmatic contemporary Fiat 500. Said super mini eventually regained composure and passed, observing a welcome 1.5 metre gap a few hundred metres later.  

Three miles from hot coffee, I swept around a bend to discover a young man tending to his motorcycle. I called out, checking he was OK; he affirmed this and explained his motorcycle’s final drive chain has snapped. This was literally 50 metres from where I was performing link surgery the previous Tuesday evening.

I offered to call someone but he politely declined, much as I did at his age and continue to. In parallel with the sheer fun and freedom, Cycling and motorcycling tends to engender a fierce sense of self-reliance.

We wished each other safe journey and I spun my way home, fingers and toe boxes nipped with chill. Next morning, I took the same route and saw his machine parked on the verge. I’m hoping he got home safely, acquired a new chain and is back to enjoying his machine again.      

These Super B professional cable cutter and inner cable puller arrived this week. We’d hoped to get them in ready for the Univega’s rebirth but no matter, these things can’t be helped and it’s timely enough given the stage I’m at with Graham’s GT. 

In common with other workshop kit, such as work stands, cable pullers aren’t essential but make maintenance and repair jobs that bit easier and quicker. Cable pullers; sometimes referred to as fourth hand tools tension the inner wire, leaving yours free to nip everything tight. Care is needed to avoid over-tensioning when feeding the inner wire into the slot but that’s as difficult as things get.

A decent set of snips, by contrast are the staple of any basic toolkit and will repay their investment countless times over. To some degree, there’s no limit to what you can spend. £30 odd is my benchmark and these Jagwire Pro my all-time favourites to date, anyway. http://www.sevendaycyclist.com/jagwire-pro-cutters  At £29.69 the imaginatively monikered Super B TB-WC30 are quite a bit cheaper, which fuelled my intrigue. Will be interesting to see how they fare in the longer term too.       

Elsewhere, John Moss has been plagued by a slipping Alfine set up. He attributes this to the manual system, so is talking in terms of upgrading the mango to Di2-price dependant. Mercifully the tandem’s Nu Vinci hub seems to be behaving itself impeccably since its rebuild.  

The same goes for the Univega, aside from another chain breakage-easily sorted with a few spare links and this Pedros multi-ttol. The 1x9 set up has enough range for long hills and fast descents. 

Full length guards offering ample protection from winter’s slimy slurry and of course, rural backwaters.The highways agency appears to be encouraging farmers to resurface with generous helpings of dung- even its Time ATAC aluminium pedals were showing signs of being engulfed. 

I also resurrected the Geonaute G-Eye2 to capture some footage. Lazily described by some as a poor man’s Go-Pro, it’s less intuitive than the Tom Tom but still offers decent image quality for a budget model.  

Right, I’ll leave you with the Visijax Gilet review http://www.sevendaycyclist.com/visijax-led-gilet

Changing Gear







I’ve just recruited an intern to work on Stenning photographic and we’re also recruiting a design assistant for Seven Day Cyclist (www.sevendaycyclist.co.uk ), which is moving from a downloadable magazine to arguably more accessible web format after Christmas.
December’s frenetic countdown to holiday season requires schematic planning to avoid a lull come January, so while relatively tired, there’s no let up.

Sabre tooth man-flu has also relented sufficiently as to permit clear thought processes and a return to serious testing. However, my susceptibility to chest infections means climbing and similarly strenuous exertion still induces the sort of hacking cough synonymous with long-serving, chain-smoking shipyard welders!

Wilder weather fronts have also prompted my Univega’s swift resurrection, though thankfully the gritting Lorries appear to have gone home. Said Tubby tourer’s more upright stance is hardly aero but widely spaced gears provide ample grunt for winching, bombing and cruising.

Big tyres also permit the odd crafty cut through and provide a magic carpet ride now that pot-hole season is in full-swing. After several weeks traversing, wet, greasy rural backwaters, the otherwise likeable Teflon prep was showing signs of embedded filth, prompting a thorough degreasing and some Fenwick’s Stealth.

Generally speaking, bells on bicycles induce eye-rolling- a well-timed yell consumes no handlebar space, costs nothing and is more effective.

However, Oregon based ORP have combined a genuinely capable three mode 70lumen light and 76/96 decibel horn in one blinkey sized package. I’m a big fan of the cutesy silicone blinkies in blanket narrative. This one is available in seven colours and protects the unit from drop and weather damage.

Diodes, circuitry and lithium polymer cell are neatly sealed in a similarly tough polycarbonate body and tucking the USB port firmly underneath, sandwiched between the bars further minimises the likelihood of dirt and ingress getting a look in. 

Prodding the rear “Whale tail” downwards unleashes a more subtle, though attention grabbing bleep that warns pedestrians, walkers and runners of your advance without driving dogs into a braking frenzy.

Upwards delivers a much louder warning, which has dissuaded a couple of learner motorcyclists from making a risky manoeuvre and some drivers from swinging doors open without looking. The diodes also flash a visual warning and the design’s a marked improvement over other battery systems.

In constant mode, the light is just about good enough for well-lit town work and has saved my bacon a few times-most notably when the Univega’s 800lumen dynamo lamp was slow on powering up. Otherwise, flashing modes are perfect companions to these and other main lighting.

Run times are quoted as 12 and 6 hrs respectively, which will depend upon how often the horn’s engaged but like most lithium ion/polymer fuelled models, seems pretty faithful to those quoted and unaffected by factors such as temperature.          

Debate has always raged as to what constitutes serious cycling with people proving particularly sniffy in the contexts of commuter/utility apparel. While I’m most commonly seen blasting along in technical fabrics, it’s worth remembering typical car journeys are less than two miles. This sort of distance can be ridden at reasonable speed and comfort wearing everyday street clothing-a mindset most apparent in the Netherlands.
Similarly, while my preference in terms of commuter lid errs towards well ventilated, sub 300g models with less aggressive profiles and trail DNA, I’ve been pleasantly surprised by this ABUS Hyban. Tipping the scales at a relatively portly 380g; it sports an ABS hard-shell, which is available in six different colours, shrugs at the inevitable everyday carelessness and has a more flattering feel when riding in civvies.
A few years back, feeble watch battery fuelled single diodes integrated within the thumbwheel closure were the preserve of upper end commuter models. Increased demand and plummeting prices means we’re getting sensible, user friendly LED lights integrated within the shell.
Admittedly, these only constitute tertiary lighting but intelligent positioning means they’re aimed squarely at driver eye-level and visible to around 80 metres-further on clear nights. Though relatively well-ventilated and employing the inlet/exhaust system, I was still surprised by how unobtrusive the Hyban felt-even over distances of 15-20miles at a steady 18mph.
Much further/at faster speeds and the increased weight becomes evident, so not a design lending itself to weekend touring. However, many scoots to the office, visits to friends and similar bike as car journeys are much shorter in any case.
Sturdy shell and surprisingly useful peak come into their own on more adventurous mixed terrain commutes encompassing forests, canal/bridle paths etc, while the former provides useful platform for cameras and lighting. Increasingly, it’s difficult to find bad products per se and these must be evaluated according to their intended purpose(s) and comparable designs, not ill-informed preconceptions.

Stuff ‘em in your Sack




The arrival of these understated Louis Garneau Lathi gloves prompted me to reflect on the contrasting approaches of two riders when it came to condition specific illumination. I’m not calling for legislation compelling us to don day-glow and engage lights during daylight hours since this serves to perpetuate perceptions that cycling and the great outdoors are hazardous by default. Compelling motorcyclists in Scandinavian countries to do just this had a very short-lived effect before they once again became "invisible" to swathes of much larger traffic. Proponents of these and similarly ridiculous measures are myopic to the fact most cyclists are also car owners/drivers, sometimes motorcyclists and truckers too!
The rider pictured blazing a trail through the 4pm December murk couldn’t be more conspicuous (In fact, temptation urged me to draw alongside and ask what systems he was using but didn’t, since in his cleats I’d construe such behaviour as driver harassment). Driving back from assorted quick stop-offs during the sleepy corridor that leads us to the New Year; I was horrified to encounter an arguably more seasoned Cannondale rider with literally zero illumination. Any of us can (and probably have) been caught out by a snagged dynamo wire, expiring lead-acid battery or similar act of god but to find him bereft of even the thinnest slither of Scotchlite, let alone contingency blinkies at half-past dusk stops short of reckless. Most micro LEDs are visible from around two hundred and fifty yards, often more but driving at 40mph in 60mph zone and with unhampered vision, I only noticed him at forty yards. What if my approach had been more cavalier or my reactions/senses hampered in some way?

Cyclists and similarly “minority” traffic take disproportionate “stick” from various lobby groups as it is and the majority of us keep our houses very much in order but these incidents are precisely what gives credence to buck passing us n’ them pressure groups’ cries for greater anti cyclist legislation. Unfortunately too many careless, uninsured and sometimes unlicensed/inebriated vehicle operatives walk away from court with a few casual nods of remorse to the judge. The mighty little blinky cost next to nothing, doesn’t detract from the sleekest steed and may be the difference between a warm soak in the tub with the rides’ highs lows swooping through your consciousness or a cold, clinical mortuary slab. Stuff ‘em in your sack.

Happy New Year!
