Mother, I’ve had the clap!













Ok, so I’ve had more difficult conversations with my mother, and I don’t mean VD. I am of course referring to that strange Thursday night phenomenon that is applauding keyworkers, during the UK lockdown. I understand this is well-intentioned and induces a sense of morale and cohesion. However, if people want the NHS and other front-line services to continue, they need to target politicians and lobby for proper, sustained investment.  

Obviously, model portfolio-building https://stenningphotographic.blogspot.com/2020/ and similar, social photography is out just now, so I’m supplementing my other freelance income with some temping. In short, an agency rang to discuss my experience in a previous front-line trade, offered me some work (I needed the money) and here we are.  
Spleen vented, back in the saddle... 

Much as I predicted, after another 150 miles, the Giles Berthoud Saddle has conformed to my sit bones, church pew numbness a long and distant memory. Nonetheless, it’ll be another few hundred before it assumes the same, subtle support provided by this Ti railed Spa Aire but compliant enough for now. Some might say masochistic, though I’ve found strangely satisfying. 

Checking my Univega’s chain, it’s in very good health, 600 miles in. On present form, I’m reckoning another 1200 before it passes on, to The Great Bike Shop in The Sky.  
I’ve another KMC waiting in the winds and was tempted to load up on another, when I remembered seeing a packet fresh, gold Sun Race unit, during my last rationalisation of the garage. Unless I spot something suitable going for the proverbial song, I’ll use existing resources. 

I’m sticking with a two-coat helping of Zefal Pro Dry lube for now, since the weather’s turned damp again. I’m also thinking in terms of switching to Weldtite TF2 Ultra Dry Chain Wax https://www.sevendaycyclist.com/weldtite-tf2-ultra-dry-chain-wax if conditions remain arid, Weldtite TF2 Performance All Weather Lubricant https://www.sevendaycyclist.com/weldtite-tf2-performance-all-weathe if the forecast favours precipitation. 

It has this week, which has presented the ideal opportunity to put a budget waterproof commuter jacket through its paces. £70 generally buys a garment that is more waterproof, than breathable. That said; I’ve been able to bowl along for 20 miles or so, at a steady 18mph without feeling “boiled in the bag”. 

Commuting continues to rise in popularity, given the present situation and desire to avoid crowded public spaces/transit. Brompton’s iconic small wheeler is a solid contender for those looking to ride shorter distances and wanting something that will go, stop and handle in good proportion. We’ve been putting their B75 through its paces. https://www.sevendaycyclist.com/brompton-b75      


Zefal has also kindly sent me these crank and paint armor, which should keep my mile munching mainstay looking fresh. I’ve gone over to these Continental Speed Reflex tyres, to see whether they’re any sprightlier than the mighty Schwalbe Marathon Mondial Double Defence https://www.sevendaycyclist.com/schwalbe-marathon-mondial-tyres  .

Formative impressions are of a quick rolling, compliant tyre with decent grip but 400-500miles will give much better insight into their characteristics, pros, cons etc. 
I’ve also switched to these long serving and slightly careworn Scott sport shoes. They’ve served 12 years, on and off. They’re a twin bolt road model with stiffer soles than the Triban 500 I’ve defaulted to, these past few months.  

They've also got a set of specialist insoles which corrects the (minimal) femur imbalance, which can otherwise induce misalignment and shoulder pain, on longer rides.  Took the opportunity to whip on some new, genuine Shimano cleats, too. Despite nylon washers and other, vibration thwarting goodies, mudguards and other little fasteners still work themselves loose.  

Some low level but annoying chatter was traced to my Univega’s SKS Bluemels Shiny Mudguards. https://www.sevendaycyclist.com/sks-blumels-shiny-mudguards Though most fasteners are now Allen, or Torx, mudguards are still 10mm nuts. I always carry a Y type socket wrench. (I’ve had it for 30 years) but Topeak Alien ii still has the 8,9 and 10mm ring types for these little jobs and I’m really pleased to see it, still in production.

Too Much Pressure?









There’s been no relent in the wet weather. Thankfully, my Univega’s dressed for foul conditions and mixed terrain service. Besides, I needed to test the mud-shedding prowess of these Wellgo MO94B pedals https://www.sevendaycyclist.com/wellgo-m094 and cast my own, personalised imprint in the Cycles Berthound Solour leather saddle. 

After 85 miles, the latter and I were in friendly acquaintance territory, 150 miles in and the friendship is blossoming. Regular feeding of the hide, using Proofide, or a similar quality leather preserve also helps accelerate this process. Once forming is complete, feeding need only be done every 6 weeks or so.  

Existing gearing was low enough to winch myself through the thick, boggy mud. However, I’ve concluded a 38 (rather than 40) tooth ring would strike the elusive sweet spot. Enough zoom for the flat and descents, just a little more grunt on the climbs.  

Production 5 arm 94 BCD rings are getting harder to source (although I am advised that Stronglight still list them). I’m not prepared to pay “classic” prices for NOS (New Old Stock) rings either. However, the existing Talon ring is in rude health and if something suitable comes along, brilliant, if not the gearing is, in the main, perfectly serviceable. 

While I’m delighted that high quality, small scale manufacturing/engineering is very much alive, sourcing products from Europe and indeed, elsewhere could become fraught with difficulty, come 2021.  

Unfortunately, highly skilled engineering and similar vocational education is (and has long been) regarded as a poor second to academic learning. A long-standing snobbery, which is neither accurate nor desirable.  

I graduated 25 years ago, during a recession. During this period, I was also keen on pursuing a new life in the Netherlands. I had a girlfriend studying there. Catching her aside her housemate (who had a 1st class honours degree), seemingly ingesting his enviable intellect saw any love for her evaporate, replaced by a strengthening bond to the Dutch.  

One thing led to another and I decided to check out the cross-country mountain bike scene there. I met an ex-pat and former banker who had relocated from the UK and retrained as a skilled machinist. Decent salary and standard of living, too. He’d never looked back. 

For the uninitiated, a skilled machinist operates machine tools to manufacture and repair precision equipment. It requires a solid understanding and application of mechanics, metals, layout and machining procedures. Apprentice trained engineers are life-lomg learners by nature and continuously develop their knowledge/skillset.  

The same is not necessarily true of University graduates, regardless of specialism-at least, here in the UK.  In the late 90’s, the UK administration introduced life-long learning accounts. A system, which was well-intentioned and originally aimed at people made redundant, when traditional industries collapsed.  

Unfortunately, this didn’t reach the intended/target audience, so it was quietly disbanded. It was recently resurrected as part of the Liberal Democrats’ election manifesto, and once again, been consigned to the vaults of history.  

Observing the patterns, I do not feel we will reach a point of total automation, where human labour/skills are made redundant but the skills required (and to some extent, legal/insurance implications) will need to change and it is quite possible that many people will be unable to make these transitions.   

These will not replace important “soft” skills, such as emotional intelligence, which are also incredibly important, in any role requiring human interaction. For example, a heating engineer who communicates well and problem solves on this level, is also likely to have more customers than one who is technically very competent but lacking in inter-personal abilities.   

I’ve been chatting a lot about handlebars in recent entries, specifically Soma Condor and Genetic’s D-Riser family. These are riser drops and some would argue, more specialist than required by some road-biased riders. Arguably, components on complete bikes should be proportional to frame size e.g. stem length, bar width etc.  

Similarly, there is a perfectly reasonable argument for making substitutions/upgrades at the point of sale. Tyre and saddles are two prime examples. This has changed slightly, given modern retailing- the switch to online, rather than physical shop consultations and purchases.  

However, unless something is obviously the wrong width/pattern/size, there’s an argument for running stuff a little while, then upgrading/replacing at a later stage.  At £30, Steve reckons the Genetic STV Road Handlebars are a great starting point for generic, road-biased riding.     https://www.sevendaycyclist.com/genetic-stv-road-handlebars 

Continuing my theme, some inexpensive but cheerful “Lifeline” branded tooling arrived, including this digital tyre gauge. Even though those fitted to most track pumps have much closer affinity to reality, getting pressures spot on gets the best from tyres and ride quality. Capable of registering 160psi, the digital is a little small, compared with a  Topeak Smartguage I had some 15 years back.   

However, in common with this premium quality SKS unit (that’s been loyal to me for a decade, or so), it features a useful backlight. Another similarity is the dual (rather than “smart”) valve head. There’s no denying the “Smart” type, which automatically morph to fit Schrader/Presta heads are super convenient.  

However, in my experience, the sprung mechanism is their Achille's heel, eventually going the self-destruct route. It also features a bleed valve, for quick tweaks and runs from the ubiquitous CR2032 button battery.  

Giving change from £10, it doesn’t feel fragile but it will be interesting to see how accurate and durable it proves. The backlight and valve light and similar features suggest it’s intended to be taken along for the ride.  

Given the price point, if it did take a bad knock, then cheap enough to replace. Nonetheless, I’m more inclined to carry an analogue model, such as this Revolution, since there’s no risk of accidental, battery draining engagement.         

There is a perception among some, that tough tyres “suck the joy out of riding”. However, this needn’t be the case. The Schwalbe Marathon GT https://www.sevendaycyclist.com/schwalbe-marathon-gt-tyres are relatively portly but still deliver a very smooth and relatively quick ride.  
I’ve had a couple of flats over the past few years and countless thousand miles. 800 odd grams is pretty much as portly as I’d want to go. Nonetheless, I’d prefer a few additional grams and reclaim riding time, over tending punctures on dark, rainy nights.
