Money For Old Rope?









 

It has been suggested by some that gravel is little more than repackaged 90s cross country mountain biking. As a means of starting debate, it’s a good opening line. I disagree. Any sweeping statement is by definition inaccurate. As with any other genre of riding, gravel will mean different things to different people. 


I removed the Topeak MTX Trunk Dry Bag Topeak MTX Trunk Dry Bag | cycling-not-racing (sevendaycyclist.com) and gave the DX rack a clean. Some grittiness had made inroads into the centre channel’s powder coated finish and there was some fastener taint. Both easily remedied with a drop of chain lube and some Motoverde Waterless Wash & Wax Motoverde Waterless Wash & Wax | cycling-not-racing (sevendaycyclist.com). Lastly, I switched the Ergon All Road and Ritchey saddles around. Both have proven good choices for me, but I was keen to see how well the Ergon performed with Denise along rougher roads and trails. 

I would argue gravel is an evolution of cyclo cross, which started with models such as Specialized’s Tri Cross. Cyclo cross bikes with daily driver friendly features such as mudguard and carrier mounts, several bottle bosses and wider gearing. Running in parallel, we had the adventure bike, which were tour friendly cyclo cross bikes with longer wheelbases, bigger clearances and tour-friendly geometry, disc brakes, braze ons and a hint of MTB DNA. 

  

For me, gravel is the lovechild of adventure tourer and thoroughbred cyclo cross bike with some XC mountain bike DNA for good measure. Some more, some less. Some competition models are closer to pared to the essential's cross builds with bigger clearances and hydraulic stoppers. Though very capable, they’re a little too prescriptive for my riding needs/tastes. I’m also very fond of the suspension tech evolution-seat posts and stems, specifically but feel that a fully blown suspension for is, for me, pushing things too close to full blown mountain biking.   

 

In its purist sense, the internet is a fantastic resource (allowing of course, for the mine of mis and disinformation). It allows us to experience and share skills and information at lighting pace and in our own time. Since my early teens., I have always been fascinated by manufacturing processes.  

 

Frame building and enamelling/paint being the most obvious. Yes, these were the starting points- I’d needed a frame built/repaired and/or refinished by a skilled and sympathetic workshop, but it extended to other areas- an interest in building my own touring trailers along the lines of Bob Yak. During these years, aside from some welding and unrelated professional courses, much of my formal learning was academic. 

  

I have always held a desire to learn wet spray refinishing along with powder coating, if only for my own projects and amusements. Having finished listening to You Tube stories while drafting copy, You Tube waved some interesting channels and gravel cycling in particular.

channel where he discusses his latest gravel build and disc mount, before showing the start to finish wet spray. He’d gone for an orange and spatter effect. I was sat there transfixed as the grey primer tubes came to life in a bold orange. 

  

I’d seen this before obviously, and it’s never lost its magic. As with so many things, a skilled person makes it look effortless. I watched Mario Vaz in his paint shop and marvelled as the paint magically stopped at certain points.  

 

During our conversation, he reflected and said one of the things he really enjoyed about paintwork and stoving enamels in particular, was that every colour is different to work with. Aside from the obvious satisfaction in being able to undertake the work to a high standard, there’s the other long-standing narrative about me not wanting to be reliant on or beholden to anyone else. At least no more than is strictly necessary. 

 

I’d been contemplating the fixed gear winter/trainer’s gearing and chain tension. The Pirelli Angel DT’s flat was another tiny sharp that had grazed the tube, hence the slow pressure loss. An easy fix, but given the bike is now more road-biased, I went for a 28mm Schwalbe One 365, which gives a gear ratio of 70.7 inches, greater clearance and a more responsive ride


Changing chain tugs, for some nicely made, long-serving Genetic and opting for a previously cut, but unused KMC S1 proved the cure. It also presented an opportunity to check the rear Halo sprocket's health. Fixed drivetrains are simple but take a lot of stress-especially if you, like me, don’t run a rear brake. Replace chains regularly and get the tension right to prevent reduced efficiency and accelerated drivetrain wear. Talking of drivetrains, I'll end here with Steve's review of Blub Bio Degreaser Blub Bio Degreaser | cycling-not-racing (sevendaycyclist.com)

Back To The Old School











I’ve managed to acquire sufficient chains and control cables for personal consumption and am delighted with Ursula’s Kinekt2.1 upgrade. This final switch has realised my 80’s vision of a drop-bar all-terrain bike. An engaging, lightweight go anywhere, four season’s machine 

One I sketched, while completely disconnected from the school curriculum and for the most part, my classmates. Sketched without a clue as to how it might be realised, I might add. Daydreams alternated between building a bespoke frameset of my own, to buying something high-end.  


While I would never snub a genuine opportunity to build a frame (as distinct from attending a frame building course) I have decided paying a frame builder, such as Lee Cooper Home - LEE COOPER CYCLE FRAMES (webs.com) to execute my vision, or buying off the peg framesets are more cost-effective, time-efficient options for me.   


Now, I’d be the first to point out that the cynic knows the price of everything and the value of nothing. Building a frameset on a residential frame building course would be incredibly satisfying. However, my money is better invested in a suitable welder and tackling less specialist metalworking projects. Some for my own enjoyment and home economics, other for more immediate, fiscal gain.  

  

Ursula’s frameset is 24 years old, in my possession for 22 of them (bought new old stock). I’ve switched the Zefal Adventure R5 Waterproof Saddlebag ZEFAL ADVENTURE R5 WATERPROOF SADDLE BAG | cycling-not-racing (sevendaycyclist.com) for this Carradice SQR Tour, which is twenty years old. Its waterproof cotton-duck fabric has cultivated a faded patina, but for me, this just adds to its character and testament to its build quality.   


Portly compared with bike packing luggage and can be a handful, laden to the gills but lighter and nimbler than an expedition rack and pannier configuration. Besides, I’ve the trailer for those occasions when I want to haul heavy/awkward loads.  


Unexpectedly, shifting had become unreliable. Cable was the most obvious culprit, since the chain had only recently been replaced, cassette was good. Ditto rear mech and hanger... Inner and outer cable replaced but no matter how much mechanically sensitive tweaking of the rear mech, the brifter remained out of step and a little sloppy.  


Dejected, I packed up for the day and after some reflection, decided on some Tektro RL340 drop levers and a Microshift ten-speed bar-end shifter. This combo might lack the outright refinement, dare I say convenience of Sti/Brifters. However, I ran a similar configuration (Shimano Ultegra) on the original build and there are several distinct advantages, especially on a machine of this kind.  


Aside from reduced vulnerability, in the event of a spill (worst case scenario, they are also cheaper to replace). Shimano Ultegra and the Microshift bar end shifters can be switched to friction, should need arise. Setting up the Microshift was more time-consuming, than the Ultegra.  


However, it all came together nicely, once I decided to take the gear cable in a more ‘cross traditional direction.  Part of the challenge and satisfaction of working on bikes (and machines generally) is working things through and getting them right. 


This also spelled the end for the discontinued (and in my view, fabulous), Control Tech bar tape and prompted a switch to the Soma Condor2 Shallow Drop Bars SOMA CONDOR 2 SHALLOW DROP BARS | (sevendaycyclist.com), since I was in the mood for switching things around. For the time being, I’ve dressed them in the orange Acros Silicone Wrap Handlebar TapeLONG-TERM TEST: ACROS SILICONE BAR WRAP | cycling-not-racing (sevendaycyclist.com), which is a more flattering contrast than I’d anticipated.  


The Peaty’s Bicycle Assembly GreasePEATY'S BICYCLE ASSEMBLY GREASE | cycling-not-racing (sevendaycyclist.com) although will revisit in the depths of winter to see how well it performs, long term and in more challenging conditions.  This enforced leave, coupled with the good weather meant I’ve been getting the miles in on the Teenage Dream and enjoying every moment.  


However, the BBB guards had finally succumbed to fatigue at the mounting points, resulting in some periodic but irritating binding. I’ve stripped them, which has obviously solved the problem while resulting in a cleaner aesthetic.
