Silence is Golden






Icy weather in remission, it was time to switch back to my beloved fixed. I’d also received this rather nice Fizi’k Vento Solocush tacky handlebar tape, and a Tioga city slicker (700x32c) tyre. The Fizi’k Vento Solocush Tacky handlebar tape, is reminiscent of other tacky, polymer based tapes. Including Lizard Skins DSP bar tape https://www.sevendaycyclist.com/lizard-skins-dsp.

I wasn’t expecting the additional .2mm density to have much impact, especially when dressing the bars. However, it required a firm, consistent approach to achieve aesthetically pleasing results. In common with similar tapes, it was very tolerant of being rewound, which was welcomed.

These sorts of finishes require more delicate cleansing (no harsh chemicals, or brushes for that matter). Otherwise, you’ll strip the non-slip layer. I was also surprised by how readily minor traces of dirt/oil and grease transferred. So, best to wear/change examination gloves, if new tape coincides with more generic servicing/repair.  

Plenty of additional incentive to get out along the lanes. However, I have noticed a palpable and pronounced surge in aggression-across the board. 

Observation and first-hand experience, on two wheels and four, leads me to hypothesise people are increasingly angry and entitled. This leads to an emotionally immature, and extremely dangerous “might is right” mindset. Rather than considered, cooperative and intelligent approach to road use.

I have often wondered whether this has any connection to a wider sense of societal angst and popularist politics. Popularism can be defined in a multitude of ways. For me, it describes a knee jerk, simplistic, emotional responses to complex issues. 
Popularist ideologies appeal to those, who know nothing about the world, are disinterested in exploring possibilities and simply want these prejudices validated.

Talking of prejudices, while in the midlands, collecting my wheel, from John Moss, I suddenly got thinking about my Univega’s mysterious (phantom) creak. Bottom bracket replacement sounded like a reasonable starting point.

Then I got to thinking along other lines. Firstly, the idea that the left-hand crank might be the culprit. Perhaps the alloy taper had warped slightly, preventing it from staying snug on the arm. This prompted one of those infamous, late evening trawls of the online auction sites, searching for a suitable replacement crankset, at the right price…

Having placed a couple of (mercifully) unsuccessful bids, I then reflected upon recent changes. Pedals being the only component switches. So, I reverted to the venerable Ritchey patterns, gave the crank bolts another quick check, then headed out for another twenty-mile blast.  Smooth, progressive silence

This appears to have cured the problem, so, being a perpetual fettler, I am, I’ve swapped to these Wellgo RC713, which offer excellent ground clearance and surprising amounts of support, even on longer outings. However, there’s no doubting double sided designs have a slight edge, at the traffic light grand prix.  

I was tempted to swap to a rather nice set of single sided Time. However, these would require swapping over to the time cleats. Sticking with SPD means I can alternate between fixed gear ‘crosser and Univega, without having to consider footwear choices.

Back on the fixed, I was enjoying some headspace along the lanes, when a mile from home, a slow rear puncture struck. I was able to creep the final half mile, on 35psi. The Gods had decided it was time to instate the Halo track HG wheel, built by John Moss. https://www.sevendaycyclist.com/love-resurrection-john-moss-s-tandem 

Now, there’s a lot to be said about this hub. One side is threaded for a conventional track sprocket and lock-ring. Bearing quality and weather sealing are also very high, well suited to the real world. In this instance, hollow Cro-moly axles turn on super smooth, Japanese bearings.

Refined and very reliable but nothing out of the ordinary… However, the other features an HG cassette type body, designed for Halo’s dedicated 7mm sprockets. These slot on the splines and are locked in situ, using a traditional Shimano type tool. No need for chain whips and primal grunting.

Yes, traditional HG sprockets may fit…

However, they will wear through the splines. You have been warned. It will accept sprockets between 12 and 20 teeth. Caters for pancake flat, hillier regions, or indeed, trail duty too.

The other significant feature is the ability to get chainline absolutely bang-on (between 41 and 52mm). This is particularly significant on conversions, which have generally required bevelled sprockets to compensate.  

I gauged spacing by studying that of the Aerorage wheel. Panned out exactly as I’d hoped. Sliding the 15tooth sprocket home, I added a moderate lick of grease to the lock-ring.

Snugged tight, I mounted Schwalbe rim tape and their 35mm Marathon GT tyre. https://www.sevendaycyclist.com/schwalbe-marathon-gt-tyres  I wanted something super dependable but relatively sprightly. The GT roll a lot faster, and smoother than their weight and profiles suggest. Looks like a great package and one I can’t wait to get testing!

Gravelly Patter &Model Behaviour






Had another extremely pleasant and productive photoshoot last week, this time at Studio Six in Writtle https://studiosixchelmsfordhire.wordpress.com/2015/06/24/studio-six-website-is-up-and-running-well-not-quite-but-this-will-do-nicely-until-it-is/ .  Well-equipped and spacious, Kathleen was the perfect host on hand with tea and skilled studio support.
Sony A6000 played nicely with remote flash triggers, suggesting it’s a temperamental streak with the older Alpha bodies. I’ve another studio shoot lined up after the core bike show and a February (location) gig in Peterborough.
Building rapport and communication are crucial to a comfortable experience and ultimately, high quality images. In the main, experienced professional models have required very little direction and during the first hour, I prefer them to lead. Past this point, a more experimental, collaborative flavour takes hold.
My stance is to communicate in detail, the moment a shoot is booked, developing rapport and a clear understanding of both model and photographer. This preparation avoids ambiguity and establishes the other’s comfort zones. References certainly help but life experience and a highly attune intuition are equally important.
Legally, in a shoot where the model is paid, images I take are my property and can be used accordingly. However, I work with the model and will only release/use those that both parties are comfortable with.
I read people very quickly and politely swerve those, who raise red flags. Safety for model and myself are paramount. I will never work alone-a third party (ideally neutral and female) must always be present. Again, I graciously decline anyone indicating resistance, or failing to grasp my reasons for doing so.
I’ve also been approached by Instagram “influencers” offering me the “opportunity” of exposure i.e. I chauffeur them to locations, shoot all day, hand them the unedited images afterward, cannot add any watermarks, or indeed receive public credit…
As a marketing case study, yes, there’s a lot to be learned from them. However, anyone buying into this “Power of Social media exposure” line with no money, credits, or rights is genuinely stupid.
By contrast, TFP (Trade for portfolio), where both parties exchange skills and time is perfectly acceptable, in certain circumstances.  Just as “You do the plumbing for my extension, I’ll plaster your walls” might be.
Sabre tooth man flu in remission, fettling also resumed. Soma fabrications Shikoro tyres came up at 36mm when I measured the front (at 85psi), suggesting the Ilpompino’s rear triangle might also swallow one without tickling the chainstays...
Lo and behold, it did. Admittedly clearance was as close as I’d feel comfortable with but acceptable, nonetheless. I also discovered a couple of spare Co2 cartridges, which were added to the wedge pack before distraction took me in another direction.
I’ve also resurrected a Zefal Z console front pack and tethered it to the Univega’s top tube. Decided carrying some additional spare butyl was a good idea and while it’s perfectly possible/acceptable, to stuff ‘em in a jersey pocket, I prefer to keep a couple on the bike. No danger of discovering they’re in the other jacket when you’re miles from base on a cold and rainy night…
A 90minute celebratory blast along the backroads and singletrack lanes last Sunday morning quashed any concerns and brought a big grin to my previously forlorn expression.
At 464g apiece, they’re a good deal lighter than the Schwalbe Marathon GT staples. This was very apparent when accelerating. Even pushing them hard along slimy sections, with 90psi in each, the supple casings just bit deeper, providing oodles of grip.
Look closely at the dimpled tread. This doesn’t add anything to performance in the latter context, rather is designed to protect against flints and similar sharps. More to this than marketing puff, if the past 100 mixed terrain miles are anything to go by.
On the subject of tyres, the recent slippery conditions and increasingly poor road surfaces (I’ve literally seen holes opening up in front of me)  have presented the ideal opportunity to see how well the Schwalbe Marathon 365 live up to their name.   https://www.sevendaycyclist.com/schwalbe-marathon-gt-365-tyres-in-w
As for the nasty lube. Well that has clung on, come hell and hell water-400 road miles between reapplications is very reasonable. It’s remained relatively clean by wet, petrochemical standards, so less call for cleaning the outer plates. There are some riders who will pour scorn on any bike specific chain lube. Chainsaw oil is a particularly good substitute, alongside 10w/40 motor oils.
However, don’t make the mistake of thinking this applies to all engine oils. Modern petrol and diesel variants are developed with sophisticated detergents, designed to clean deposit and regenerate, under pressure of the fuel pump.
Drizzle these on your bike’s chain and it will be serene to start with. In as little as 35miles, chances are those additives will have stripped the lubricant layer, resulting in that familiar, thirsty tinkling.
I’ve tested a lot of lubes over the years and have some very firm favourites, although I’m yet to find one that is perfect for all conditions/contexts. I like clean formulas, so have high hopes for this Smoove Universal chain lube, which reached us in spite of the seasonal postal pilfering. Now, judging by the latest forecasts, I might be whipping those spiked tyres back on…

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

Grinning Through The Gloom












These Schwalbe Marathon GT tyres arrived for testing from Schwalbe UK. Ours were the narrower 35mm section- nigh on1.4 inches in old money but there’s an even beefier 38mm, which seem a fitting choice, for the latest generation of disc equipped tourer, or tarmac tamed cross/gravel bikes.

These are much faster than the legendary and justly revered Marathon. Something that is immediately obvious from the first few pedal strokes-they’re also significantly easier to mount-no tyre levers required. Stiffer sidewalls, 7mm and 68g apiece separate them from the generally likeable, uber plush Maxxis Roamer.

Their E-bike compliance is also likely to explain the additional girth, although the Schwalbe inspire greater confidence along the wet, silty lanes. The sort that seem perpetually carpeted in gooey dung, complete with thorny, talon-like hedge clippings.

They use the “Dual Guard” system. Rather than our old friends Kevlar/Aramid, Schwalbe employs a two-layer nylon casing and a further 2.5mm strip of India rubber that works like a trampoline, forcing sharps out, thus minimise the risk of a flat. Schwalbe rate it 6/7 and say it strikes the optimal balance between speed and puncture prevention, which sounds perfect for bikes in daily service.

Talking of which, sidewalls feature a reflective strip and dynamo track, adding to their appeal. 

Retro-reflective strip and the Chevron style water channelling grooves are very reminiscent of Vittoria Voyager hyper http://www.sevendaycyclist.com/vittoria-voyager-hyper-tyre .

Interestingly, their profiles are slightly narrower than the faster rolling, Italian brands’ 35mm section, meaning a more comfortable fit in my winter/training fixer’s rear triangle.  

Formative impressions are very favourable. 65 miles along greasy/icy back roads suggest a quick, yet ultra dependable tyre. It’ll be at least 400 before I arrive at anything near tangible conclusions.  

Meanwhile those slushy lanes see regular post-ride rinse-overs to prevent salty, caustic stuff taking hold and moreover, nibbling away at pretty paintwork and components. I’ve got this down to around 10 minutes, including a quick, precautionary squirt of PTFE based lubes on exposed cables, pivot points and similarly sensitive mechanisms. 

I’ve also reverted to the Rock n’ Roll gold lube for more staying prowess but without the stickiness associated with traditional wet lubes.          

Decent lights are imperative during the winter months and not just the retina melting type, of which I am so very fond. Often it is the blinkies, retro-reflective and tertiary lighting that first registers on a driver’s radar. Aside from the Visijax gilet (www.visijax.com ), which continues to impress me with its presence, I’ve discovered the origins of John Moss’s preference for yellow, signal yellow to be precise.

Both his Tandem trike and Mango fairing sport this shade. Having recently changed the Velomobile’s gearing for a 2x9, thus improving efficiency overall, he’s decidedly dissatisfied with attempts to repair the scuffed nose using single pack acrylic aerosols. His godson works at the sharp end of car body repair, thus is fully equipped to apply 2K. We’ve tracked down a suitable Ford shade, so watch this space...

Elsewhere, we’re a bit further along with Graham’s GT rebuild-I’ve just introduced some cheap but cheerful, Jagwire brake cables. While Graham locates the wheels and I await derailleur cables, I’ve sanded some superficial glazing from the Alivio pads and I’m leaving those stainless steel inner wires to stretch to capacity. Then I’ll re-tension, prune and superglue the ends to stop fraying before it starts.

Premium grade cable sets, such as those Jagwire Elite presently stopping the Univega and are immune to such vices-simply tension, tighten the anchor bolts and trim to size. Budget models, though generally faithful servants benefit from a different approach.

Having set cable tension, pump brake levers ten times in succession to induce some slack. Loosen those anchor bolts, pull the inner wire through again and snug tight. I lean toward leaving them overnight and re-tensioning the next morning. They will have stretched to capacity by this point, so once tweaked, shouldn’t induce any short-soiling moments when tackling a 1in4 descent. Same basic principle applies to derailleurs. 

Right, well that’s it for this entry. Off for a chat with someone about a gravel bike...
