Progress & Priorities


 












On some levels and to some extent, everything in life is a work in progress. That out of the way, I was still being taunted by the intermittent brake tickling and concluded everything was otherwise correctly aligned...Perhaps the outer housing from lever to first cable stop was fractionally too short... 

I'd had plenty of compression-less outer and had earmarked inner cable replacement, so an obvious thing to rule out and a simple fix. Something that came to mind during that meditative mid- ride phase.  

I've also been contemplating the rack and trailer compatibility conundrum.

One potential solution was to fit an adaptor that would raise the racks' legs, providing the necessary clearance without compromising the rack's payload. Now, I'm talking a high quality, properly machined stainless/6061 aluminium alloy, not the sort made from cheese. However, closer inspection of the Topeak’s “foot” revealed this a non-starter. Some folks recounted shaving metal from the foot with their trusty Dremel…Nope, not for me. Besides, braking was my primary focus-this needed to be right before we're tethering trailers.

The solution came courtesy of Madison cycles and a M Part Ridge rack. Weighing 624g, it's a single tier design loosely reminiscent of Blackburn's MTN. One that served me well until its demise while riding through Forest Gate (E7) late summer 1999. Credit to Blackburn, they honoured their lifetime warrantee and I received a replacement. The Ridge is made from 10mm 6061 aluminium rod, comes complete with a no quibble 5-year warrantee and a respectable 25kilo maximum payload.

Designed for disc brakes, it employs adjustable legs and oodles of calliper clearance without the "feet" which preclude trailer fitment. There's a solid top plate doubling as a mudguard for easy porting of rack bags and loose stuff captured by a cargo net. Stainless steel fasteners are another nice, corrosion-resistant touch. However, I found the arms too short for Ursula, preventing it sitting level, so switched them for the  Topeak's. 

Single tier models can make pairing of panniers and trunk bags less convenient than their two-tier counterparts and means weight is also positioned a little higher. All things being equal and in the everyday sense, I've never had any major issues lugging 20-litre panniers with Blackburn and homages.     

One of the most faithful homages to the Blackburn MTN was produced by Bor Yeuh. I bought one over thirty years ago for £15 and it was very much bombproof and surprisingly well-finished. There’s an argument for using threadlock on fasteners, rather than grease-especially ahead of a tour. In these contexts, I’ve always carried a few spare nuts and bolts, should one make a bid for freedom. However, I didn’t have any medium strength threadlock to hand, so added a coating of Zefal Pro ii Zefal Pro II Grease | cycling-not-racing, which should keep the elements out.

 These and other little fasteners are easily overlooked until you want to remove or adjust something. In a pinch, heavyweight wet lubes, or 10w/40 motor oil make passable grease substitutes, and I’ve found fasteners mobile a few months down the line. Nonetheless, for daily drivers and other mile munchers, re-greasing every six months or so remains best practice.  If in doubt, apply a quick squirt of MO94 Muc-Off MO94 Multi Use Spray | cycling-not-racing, GT85 GT85 ALL PURPOSE LUBRICANT, or similar maintenance spray (allowing it thirty seconds or so to penetrate) before introducing an Allen key-your frame threads will thank you.

 While rooting around in the spares boxes, I uncovered a set of solid axle mounts for the trailer. I’d acquired some along with the sprung hitch spares some years back. At that time, I’d been toying with Alfine and similar interplanetary (hub) transmissions. This never came to fruition. On a few occasions, I’ve tethered trailer and V2 fixed, primarily as part of wider product testing. Otherwise, gearing in the mid to high 70s isn’t synonymous with trailer tugging. However, 63inches might prove a better fit, should need arise.  

Using the Specialized Crossroads EX as a "control", I've done 250 miles with the Nutrak and found them grippy and relatively responsive, especially coming from 2.2-2.3-inch cross country rubber. Average speed across metalled road is 17mph against 14.5 with the Continental and CST Patrol in comparable conditions.  Even inflated to their maximum (65psi) they've felt supple and compliant without any trace of skittishness.

I'm experimenting with pressures and am forming the opinion that 50-55psi is the sweet spot for my tastes, but time, mileage and testing may say different. I'll be interested to see how they cope in gloopy mud, which may be a while off yet, given the long, hot and distinctly dry summer. My supposition is their narrower profiles, and tread pattern will crave through without clogging or causing mischief around the chainstays. 

From a personal perspective, I was delighted to find a 26x1.9 gravel tyre, alongside 700c and 650b, although I was curious as to whether Nutrak were seeking to tap into the quiet trend for mountain bike to gravel conversions. Something I raised with Madison when discussing the specifications.

 Now, they are intended as a tubeless setup, which is another nice touch for those running a conversion. They also proved a very tight fit, which is very welcome on a tubeless system, but calls for a decent tyre lever. This was particularly so when running them with a butyl tube- even aboard a very conventional cross-country rim. I was relieved to find my trusty Cyclo Advanced Tyre Removal and Fitting Tool worked its magic, saving considerable time, effort, blisters and agricultural language.  I am very particular about lending tools and there are some I will flat out refuse to let out of my sight. Said tyre wand falls firmly into this category, along with a Czech made headset press.

I'll Just...


 



January is a tricky month in every respect. The festivities forgotten, replaced by an unsettling silence. Some folks await the fiscal hangover, others plunge themselves into projects and traditionally, it’s a time of year when I disappear to the garage, fuelled by those nights where an idea can evolve into the ONLY idea.

I was recovering from a sudden, unwelcome seasonal lurgi and feeling infinitely better, (save for an infected tooth, spotted by my dentist during a routine checkup) decided I’d switch Denise to gravel rubber and complete testing of the Zefal Shield G50.Zefal Shield G50 Mudguards | cycling-not-racing Wheels fitted, tyres inflated to the desired pressure, I then discovered the rear Kore cantilevers were dragging. Hmm, just a case of changing the inner wire and a quick tweak of the balance screws.  

No joy. After some deliberation, I concluded the Tektro RL520 must be pulling too much cable, so after a quick rummage of the spares boxes, I recovered a silver RL340 designed for cantilever and side pulls and made the switch. Closer, but definitely not right.  By this point, we were coming close to midnight- I’d planned to have everything sorted and safely tucked up in bed long beforehand. Firmly in the zone, I discovered a missing balance screw, so decided to strip them from the bosses and switch to another set. This also presented an opportunity to regrease the cantilever posts with Zefal Pro II Zefal Pro II Grease | cycling-not-racing.

Refitted, snugged tight, some minor tweaking of the balance screws- sorted. Ok, so a few localised squirts of MO94 were needed, since I’d forgotten to flush the outers through in my diagnostic phase. The RL340 and 520 levers have slightly different profiles, apparent when looking down at the hoods but close enough aesthetically. Moreover, I had a fully functional rear stopper.

 Once-overs completed, bars redressed in the Ergon Orthocell Ergon Orthocell Handlebar Tape | cycling-not-racing it was 1245. Still, I’d diagnosed and cured the fault, so off my list and out of my head. A test ride the following morning confirmed all was well. Quit while ahead. Weeks and many miles hence, the Zefal Shield G50 continue to impress with their rattle-free construction and impressive protection- on and sans asphalt.

Definitely the best clip-on guards I’ve ever used and by some margin. I’m still mightily impressed by Mudhugger’s Gravel Hugger, but these are a more permanent design- none the worse for it, but slightly different. The Gravel Hugger are also incompatible with rim brakes. Fine for contemporary gravel, or bike packing framesets and the coverage is also impressive.

However, incompatible with bikes running cantilevers, or linear pulls. Talking of which, I’ve upgraded Muffin’s brake cable with a Jagwire CGX 5mm outer and stainless inner. Not on par, with their top flight Jagwire Road Elite Jagwire Road Elite Sealed Brake Kit | cycling-not-racing, but a tangible improvement. The Fibrax and bog-standard stainless inner fitted during the initial build has served well enough in the “use what you got” sense. Now it was due replacement, hence the opportunity to upgrade. A few months down the line, I wasn’t surprised to discover the MPart Primo Anti Slip Silicone Gel Bar Tape M Part Primo Anti Slip Silicone Gel Bar | cycling-not-racing had weathered. In fairness, it was re-useable and the adhesive backing still up to the job, but the finishing strips were really stubborn to remove. Should get another few months regular use before retirement. Switching to the Spa Aire Titanium has also brought a new level of bliss. I’d broken it in years ago but forgotten how comfortable it is, especially on a bike with similar positioning and geometry as Muffin.

Mercifully, save for testing, worn consumables and the odd tweak, I more or less have the fleet optimised. Major revamps and overhauls are off the table.  Invariably, when I’ve fallen down one of these rabbit holes, some other expenditure has presented, whether it be cars, dental treatment, or similar priority.

I should point out that while brutally diminished by successive administrations, we do still have the burning embers of universal healthcare, but there is still a fiscal contribution to be made. Universal healthcare makes sound economic sense. The healthier your nation, the more productive. There is an argument in favour of contribution and I can see this, but only so long as it's proportionate and based upon the ability to pay.

There is a large swathe of the UK’s population who enjoyed increasing prosperity across the board-even those in lower-skilled, dare we say “dead end” work. High quality affordable housing, good schools and other public services. Housing was about community, not assets, educational attainment and life chances were more closely associated with the communities, parents and peers surrounding you.

Nonetheless, upward social mobility was very much a lived experience. Something that progressively waned through the 1980s onward, as industries and communities died. Those that could, left and pursued new lives, those that didn’t were left behind, largely ignored. Easy prey for the populists who offer slogans, emotional dynamite but no solutions to inherently complex and ingrained problems.
