Warp Speed, Mr Sulu!










The nights are beginning to steadily creep in. A few weeks back, it was still light by 2100, now I've the dynamo and rear blinkie running at 1930 onward. Some would argue running front and rear blinkies is good practice, long before dusk. I'm inclined to agree. 

My tubby tourer's Exposure Revo dynamo headlight not only produces a very usable 800 lumens, the standlight lasts longer than most. Therefore, no problems at busy junctions. Nonetheless, anecdotally, it seems car, and other drivers respond faster to a fast tempo of a daylight/similar flash setting. Hence the ORP Smart Horn https://www.sevendaycyclist.com/orp-smart-horn and more recently, this Ravemen  LR500S USB Rechargeable Curved Lens Front Light. Clue's in the title, its a compact light with a total (and more potent than figures suggest) of 500 lumens.  


In common with its LR1200 counterpart, it uses lens technology, which is designed to provide a pure, consistent, yet road friendly beam. There are four modes. Three steady High (500) medium (300) and low (100), which should cater for town suburban and semi rural contexts, without being impotent, or abrasive. 



Run times are cited as a commuting friendly 1.6, 2.8 and 7.5 hours respectively. The rapid flash (200) is reckoned good for 15  In emergency, there's the option of plugging into a portable "power bank" and I also like the wired remote option.



Not that the switch cum battery life indicator is tricky to operate and there's a memory mode. Both the 1200 and 500 brackets are fully compatible with the different units, hence I've swapped between tubby tourer and working fixed. There's also an upside down, Garmin type option, if you're pressed for space, or despise clutter. 



An aluminium alloy casing, though not unheard of, at this price point (£34.99) is nice to see. Its shock resistant to 1 metre and complies with PPX 6 for weather repellency. Reassuring.  



Even with high power main systems (dynamos, in this instance) I always carry a second compact unit. Should I puncture/similar along a very dark lane, or snag a wire/similar, then I've always got a sensibly powered backup. Most of the time, these just do a different sort of backing singing-flashing away. Now, much to my surprise, I've discovered it has cancelled out the signal from my tubby tourer's simple little Cat-Eye Quick Computer. 



I initially put this down to a dead sensor battery, and changed the CR2032 button cell, adding a quick lick of Vaseline to the contacts, while I was there.  Spun the wheel, fine. Popped the Ravemem into fast flash the next morning and headed along the lanes. Head unit registered  0 . 
Having stopped and double checked sensor/magnet clearances, I switched the Ravemen off. With (almost) immediate effect,  the display read 14.3 mph. The moment I reengaged the little Ravemen. 0 .  
Shame too, since I was really flying along the flats and descents. In keeping with the Zefal Pro Dry Chain lube https://www.sevendaycyclist.com/zefal-pro-dry-lube and indeed, Muc-Off Dry Lube https://www.sevendaycyclist.com/muc-off-dry-chain-lube, the Rock N' Roll Gold LV one of those low friction blends that really encourages a taller gear and faster cadence. Theory goes this family are intended to be topped up, every 100miles or  so, although I've managed over 400 miles with their absolute dry (admittedly, an older formula) 



Anyone will tell you a wired connection is the most reliable. However, I've never experienced this before-with any system. Sure, older wireless models had a reputation for going bonkers, in close proximity to high currents-Pylons, nuclear power stations etc. 



88mph uphill anyone? Might just be the relatively close proximity. It's presently on the Velo Orange Handlebar Accessory mount https://www.sevendaycyclist.com/velo-orange-handlebar-accessory-mou, so I'll swap it around and see if this makes any difference.  Elsewhere,  Oxford have sent us their North Shore Off Road gloves, which are proving surprisingly capable options for late summer road riding, too. Plenty of miles to do before I cement a proper, informed conclusion. Muc Off also sent me a small bottle of their matt finish detailer, which I've wasted no time applying to a few lids.

Fettling, Focus & Filthy Fun












Having banished the banshee howl, thirty miles hence, it was replaced by pronounced mushiness. Maybe it harks back to the days of Campagnolo and Modolo with super strong springs but my preference is for levers with a really firm feel. Much as I expected, we’d succumbed to some minor cable stretch. Virtually unheard of with premium grade inner wires, otherwise faithful OEM/budget fare remains slightly prone.

Roadside repair aside, the best cure involves dialling them in to taste and pumping the lever(s) repeatedly inducing metal stretch and sloppy action. Pull the inner wire taught and nip the pinch bolt tight again. Ideally leave overnight and repeat-sorted.

Popular consensus suggests that “serious” riding only applies to competitive contexts. Hmm, long rides with friends; or indeed in complete solitude for their own sake, commuting to work, or utility aren’t??  I seem to recall this sneering, disparaging tone expressed toward mountain biking when it began capturing the British public’s imagination during the mid1980s…Horses for courses and different strokes for different folks spring to mind.

For a good decade or so, many large manufacturers have been offering great value, sensibly dressed commuter bikes. Sure 6061 or more workman-like Cro-moly framesets might not set pulses racing or tongues wagging. Nonetheless, they are extremely functional, engaging to ride and a much better bet for less glamorous duties than thin wall exotica with “steal-me” groupsets. The same principles apply to clothing/accessories.  

Many, including myself love and take their bikes; equipment and riding seriously but have little urge to participate in traditional genres of racing. In many regards Audax has become the default alternative but there’s a quiet yet increasingly popular movement towards a different kind of collectivism. Chance meander through a Colchester side street revealed Col Velo…

This is a partnership between Rob Hardwood and Will Morgan, who founded in October 2014. Their tag line suggests leaving one’s ego at the door, partaking in some coffee and joining like-minded folk for an organised, though informal jaunt.

A no-drop policy affirms this inclusive, ride-with, rather than compete-against ethos, which resonated with me, so I popped down for a chat last Monday night. 

Essentially, these are group outings catering for different abilities with pre-planned but varied routes through the more picturesque North Essex/Anglia regions. Leading out from Velo! CafĂ©’ tone is camaraderie, appreciating bikes, equipment and experiences with passion and open minds. www.colvelo.co.uk

Elsewhere, I’ve been rummaging through the spares box for inspiration, specifically looking to update the Univega’s likeably cutesy Knog NERD for something better endowed functions wise. Within in a few minutes it emerged in the guise of this fifteen-function and imaginatively monikered BBB BCP 13W. Five minutes, a trace of Vaseline on the battery contacts and fresh CR2032 and LR44 cells hence saw it burst into life.

Convenience is wireless’ main draw- simple to fit, nothing to snag during front end overhauls or just blasting along overgrown bridle path. However, assuming you calibrate wheel circumference manually and do sensor/magnet proximity by the book, wired versions remain most accurate and are unaffected by electrical currents/similar interference. 

Stem mounting is another boon, freeing up some much needed handlebar space, although the Univega’s extremely short extension means ours almost fouls the top-cap. Counting two wheel sizes and maintenance/lubrication reminders as functions is gilding the lily, borderline gimmick in the latter context.

Then again, there’s a lot to be said for a maintenance nudge given the impact neglected chains can have on 9/10/11spd groupsets. Pacer arrows and single button command are similarly welcomed.  

Genesis have sent me their Croix De Fer 2.0 to play with and I’ve wasted no time in getting it dirty, grinning all the way. Hopefully the next couple of weeks will present some more challenging test conditions.
