DIY Mount & Deore











 Large-scale manufacturing is very much a thing of the past here in the UK. There is a sense in which the nation still yearns for this, possibly as an antidote to a palpable sense of managed decline.  

There also seems a romanticised idea of the post-war period, and a yearning for its return. Hmm...petrol rationing, communal outdoor toilets, no, or extremely limited access to contraception, abortion and widespread austerity...Be careful what you wish for... One of those things I often reflect on, through the dark lanes in the wee small hours. 


I’ve always been very drawn to highly skilled people-their intelligence, humility and eagerness to learn is very infectious. Now, the relevance of this backstory? Finding a suitable mount allowing the TRP HYRD to fit a fork’s IS mount. John Moss and I were discussing our respective projects- he's been upping the gearing range on his beloved Mango.  


He seemed confident and moreover, offered to make a mount from stainless steel. I had an appointment in the midlands that week, so popped the TRP HYRD calliper, red mount, and severed Kinesis fork (as templates) into a box and 18-year-old but much-loved Specialized messenger bag. 


Upon my arrival, he ushered me and my stash to the garage and then, to the workshop. I had my trusty compact camera in pocket, so took various shots in alternate positions for John to refer to. Nonetheless, John remained convinced he could machine something bespoke, from stainless steel. 

 

He’d trace around the red mount and possibly mill some slots for a precision fitNow, this wasn’t urgent- the TRP SPYRE SLC were in good health and highly functional and I didn’t want John feeling under pressure or distracted from his own projects. However, I don’t like things that aren’t ready to go, as and when I want/need them.  


Life and sometimes ideas can be cyclical. Six years since I went the 1x9 route with Ursula After The Gritters Went Home | Seven Day Cyclist and two since I switched to a Hollow Tech II crankset, I found myself contemplating a double. Serendipity had someone waving a new 36/26 175mm crankset and braze-on derailleur under my nose for a ridiculously keen price. Decision made... 


I’d a new left hand Microshift bar con, inner and outer cables, chain(s) and indeed, an STX front mech. However, this was from the original build, and I didn’t want to get side-lined by something that wasn’t going to plug and play. Make no mistake, a lot of components will adjust nicely...  


Being a 7 speed MTB mech, the pull wouldn’t be an issue, and the travel easily restricted but I thought it best to get a compatible contemporary model and keep the STX on the subs bench. 


I also had a Microshift and Sun Race front mechs (double), but these were braze- on, requiring a suitable aftermarket clamp and, being road models, were bottom pull, thus requiring an adaptor. I’d be into £30 on those alone.  


Now, I could always whip the 28.6mm STX band on clamp over to the Deore but I didn’t want to start cannibalizing stuff. I was tempted by a BBB Shift fix, but these weren’t available in 28.6.


Thankfully, M Part does. M part is Madison Cycles' in-house range and, in my experience, nicely executed. It may also mean removing the serrated section of the rear mudguard (its deliberately engineered for this purpose). I’d run bar con shifters on Ursula’s original build (Deore XT) so knew the left-hand Microshift would be fully compatible.

  

I also took that opportunity to prune an outer housing to length, making the switch cum upgrade that bit quicker. I put some helicopter tape around the seat tube, where the front mech mount would sit against the paintwork. A bit OTT perhaps but rules out marking paint, when adjusting the mech’s height/positioning.       

 

As a side note, I’ve always liked Deore and STX/RC groups. Good performance-to-price ratios. Finish is generally decent, too. Smart enough for pretty builds but rugged-great for daily drivers and working bikes. What’s the best bike? Is a question so commonly put to shop staff. The best bike is that or those that meet your riding needs. The same applies to components- horses for courses, essentially 


Good planning and preparation are key-I've even found these KMC magic link pliers, which I’d had for a decade, or so but believed lost during the last move. I’d secreted them inside a Lezyne pannier of similar heritage. Even with the stock 11-25 cassette, I’d have a range between 26.8 and 84.3 inches. With an 11-28, I’d be looking at a bottom gear of 23.9. However, I have a quiet (possibly unfounded) concern this would put the Tiagra mech under potential strain.  


Might be a red herring but I didn’t want it imploding like the Sun Race and Micro shift did-at the least convenient moments. Not that there’s a fun time for a component’s expiry. In terms of chain length, some sites suggest I will have no issues with chains of 100 links, but this seems a little short to me. I’ll go with the existing 110 and place a little less stress on the system.  


I’ve decided to wait until the unseasonably wintry March and potentially awkward start to April pass- no sense giving the new components unnecessary exposure to the elements. It also means I could switch to the fixed gear winter trainer, should I need to “pause” with Ursula’s upgrade. That said; I’ve switched the spikes in favour of the Maxxis Maxxis Overdrive Excel Tyre | cycling-not-racing (sevendaycyclist.com) and reached my CST Xpedium CST Xpedium Tyres | cycling-not-racing (sevendaycyclist.com) conclusions.   


Why not a triple? Well, simply put, this would be excessive/unnecessary and a chore to keep harmonious year-round. A 26-inch (or 23.9) gear is more than sufficient torque for most gradients and contexts the old girl and I are likely to meet. 84 inches is tall enough for bombing without blowing knees, or spinning myself into another dimension-although some might suggest that might be desirable, given the UK’s present trajectory.   

 

I’m holding on to the single ring deore but I’ve decided it’s time to move the 170mm, Shimano Zee, since it’s a downhill crank and surplus to my requirements. Right, time for a change of lube...

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.
