Magnetic Attraction

So, with freshly rebuilt dynohub wheel safely returned to me, and Univega waxed, following some mucky January mile munching, it was time to switch to fixed. 

Following frankenpute euphoria, you’ll imagine my dismay at a flickering and sometimes unresponsive computer display. Big fat flashing zeros are not cool.  

Let us be clear (as the present UK administration is so fond of touting). I had inserted fresh CR2032 cells, adding a slither of Vaseline to the battery contacts, nipped the sensor ties and magnet tight…Most probable causes isolated.

A seasonal Lurgy curtailed further diagnostics, but all seemed to be behaving normally. Both on the work stand and a subsequent mile long loop.

Three days later, back in the saddle, out along the lanes. Dynamo on, blinkies pulsing, erratic readouts... So, I switched the Trelock LS 906 https://www.sevendaycyclist.com/trelock-ls906-dynamo-front-light  lamp off. Consistently accurate, precise readouts resumed. Fluctuations gone.  This remained the case, over two rides and 45 miles.

I’ve never experienced these symptoms with my Univega’s Ultegra, or elderly Nexus hub dynamos. However, Strong magnetic forces, such as those experienced around power plants, and pylons are notorious points of interference. 97.6mph along a long, straight road, anyone? 

 I am also advised Shutter Precision hubs have particularly strong magnets.

Carbon fibre can also prove conductive, which is why good quality greases/assembly pastes must be used on metal components, to avert risk of galvanic corrosion/seizure. Bottom bracket threads being prime candidates. Could it be that the wonder weave, is amplifying said magnetic field, and creating these irregular signals?  

This may dictate moving sensor and magnet to chain-stay and rear wheel. Doing will exhaust computer and sensor cells a little faster. But provided I don’t exceed the 1 metre rule, everything should play nicely.

A wired unit is my last resort. Aside from defeating my “make do and reinvent narrative”, I’ll need to be more mindful when performing headset strips, and similar maintenance.  Blackburn have advised they no longer keep spares for the Atom units and, surprisingly, have deleted computers from their range.

Another rummage through the bodge box unearthed this VDO M3 WL, which appears to have a sensor fault. I’ve tried all the above techniques, but they won’t play nicely. Nor any other brands, for that matter, so I’ve emailed their UK importer for help. 

Despite constant headlines threatening a second ice-age, the thermostat has hovered around a seasonally typical 5 degrees.

No call for spikes just yet, although the wind chill prompted donning of Northwave Balaclava, once or twice.  These Oxford bright 4.0 gloves https://www.sevendaycyclist.com/oxford-1

have also come into their own and Steve’s been impressed by Proviz Reflect 360 CRS Plus Jacket https://www.sevendaycyclist.com/proviz-reflect360-crs-plus-jacket  

Chainsaw oil is continuing to do the business and some 140 miles in, is probably the closest to a bike specific, wet lubricant. I’m bargaining 500 miles from a single application. On paper, it’s looking a costlier option, compared with the bargain basement 5w/40. However, the latter attracted more scuzz. Most apparent within the cassette.

There’s been some further perch swapping, courtesy of this Pro Turnix gel saddle, which now graces my fixed gear winter/trainer. Its Selle Italia Novous boost superflow has been ported over to my tubby tourer and I’ve earmarked the BBB Echelon, elsewhere. Possibly the Goldhawk Roadax, if I can’t live with its stock/OEM model.

Primal Stirrings

Despite the seasonal increase in lost/stolen parcels, these Primal Dawn men’s bib knickers made it through. Formative feelings are very positive.

Bridging the gap between shorts and thermal bib tights, ¾ lengths are perfect for autumnal and early spring rides. Milder winters too. (That said; Primal cite an optimal operating temperature range, between -7 and +24 degrees) In fact, ¾ lengths my preference over bib tights, unless wind chill/air temperature really bites. Our medium fit my 1m81, 70 kilo-frame perfectly.

The bibs offer ample coverage to the vital organs, the braces, unrestricted movement. Though less common, these days (especially at this price point) the elastic in some designs can be overly firm. To the point of feeling restrictive. Several in my collection, leaving unsightly tell-tale branding, after a couple of hours riding.

Panelling and cut seem equally precise. I managed 16miles in 45 minutes during our first outing and on the fixed. Much of that fuelled by very controlled rage, induced by an inflammatory communication, from my ex-wife. Nothing particularly new there. Another example of resilience, which I touched upon in my last entry. The season of goodwill generally slumps during December, on the roads, too.

I wasn’t surprised to find myself on the receiving end of some crass overtaking. Now, simply put, if you want to kill someone without experiencing punishment, incarceration, or indeed, loss of licence-do so with a car, or larger vehicle.

The occupant of a Mercedes Sprinter began overtaking (on a bend) but then decided he might collide with an oncoming vehicle, so just swung back. I’ve had closer encounters but was fuming at this display of elephantine ignorance.

The Sprinter remained stationary, engine running for around thirty seconds, blocking my progress. A baleful “Sorry mate, are you OK?” was offered on three occasions. I remained silent and unresponsive, partly in the hope my contempt would register. Life is very short, responding would only serve to ease his awkwardness. Hopefully this experience gave him food for thought/improvement.    

On the alternative lubes front, after 480 miles that familiar, subtle metal-on-metal tinkling struck. This coincided with a well-deserved sudsy scrub, for Ursula, who was sporting a fair bit of accumulated grot around the fork legs, bottom bracket shell and chainstays.

This was dismissed with some Pro Green MX Cycle Wash https://www.sevendaycyclist.com/pro-green-mx-triple-pack . Fenwick’s foaming chain cleaner and Green Oil bicycle brush https://www.sevendaycyclist.com/green-oil-bicycle-brush  had cassette and chain gleaming, ready for chainsaw oil.  Applied via dropper bottle, this went on in a fashion, reminiscent of Weldtite TF2 extreme wet chain lubricant https://www.sevendaycyclist.com/weldtite-tf2-extreme-wet-chain-lubr  and some others adorning my shelves.

However, I was surprised by the initial clean up required. There was a fair bit of excess clinging to the side plates and a spattery patina (reminiscent of that effect employed by Kona on their late 1980s mtb frames) adorning the Univega’s chainstays. Less drizzle n’ go than bike specific blends but not markedly worse than the motor oil, in many respects.

On some levels, its to be expected, but the fixed has been running much cleaner and the lube is really clinging to the chain’s dimpled galvanised texture. Several wet rides in, the chain has almost “bedded in” and the initial gravely patter, replaced by a serene swoosh.

Talking of gravelly, (and before the so called “beast from the east” sweeps in Steve has just reviewed these GoodYear County https://www.sevendaycyclist.com/goodyear-county-premium-tyre  

Ison Distribution have been investigating my SP PD8 dynohub wheel https://www.sevendaycyclist.com/halo-rim-and-shutter-dynohub-disc-b  and confirm the hub is fine. However, the rim appeared to be pulling itself apart (albeit, very slowly). Therefore, they’re stripping the wheel and rebuilding with a new hoop.  I’ve also decided to revisit the Univega’s front stopper.

Though the IRD CAFAM 2 cantilevers https://www.sevendaycyclist.com/ird-cafam-2-cantilever-brakes  are beautifully engineered, their mechanical advantage better suits traditional levers.

My Univega’s existing Microshift are shallower reach. Great for smaller hands, but Avid Shorty 4 and M system designs are better pairings. The humble cantilever is becoming harder to come by, although still has a solid following in ‘cross circles.  Some Shimano CR50 presented themselves, so we’ll see how they fare.

Lighting, Lubes & Log Cabins

So, I’ve reached our conclusions regarding the Ugoe 2000 headlight https://www.sevendaycyclist.com/ugoe-2000   and The Oxford Bright Stop rear LED light https://www.sevendaycyclist.com/oxford-bright-stop-rear-led-light I’ve turned my focus to mile munching with the Schwalbe Marathon Mondial https://www.facebook.com/Sevendaycyclistmagazine/videos/1367504860051913/  which are performing convincingly, both on and off road. https://www.facebook.com/Sevendaycyclistmagazine/videos/324364064784396/c

No, they’re not a trail tyre, in the cross country mtb sense. Rather they’re go-anywhere, all-terrain rubber. Sure, they’re not going to carve through the gloop like an aggressive knobbly, or glide over asphalt with the same speed as a slick.

However, rolling resistance is considerably lower than their weight and 26x2.0inch profiles would suggest. Off road, they’ll take unmade tracks, bridle path and less intense forest trails, in their stride. The stuff that really turned me on, to mountain biking as a teenager. Also explains Gravel’s appeal (much the same principle, just tackled on bikes with more cyclo cross in their DNA).

Lightweight, rugged machines that could go anywhere and perform with similar finesse. Slower across asphalt than a road or touring rig but the ability to vanish at speed along a dirt road. Feeling the ear to ear grin grow and leaving the world behind.

Powerfully enticing now, much less a bored teen, stifled by school’s rigid conformity. I wasn’t disinterested in education, just the context and curriculum. Thankfully, there were a few suitably disruptive students, for teachers to actively “zoo-keep”.

This left me to read the latest Specialized or Cannondale test, sans introspection, let alone chastisement.  My sincerest thanks go to Jane Wright (as she was, then) who rose from her seat and burst into the Communards’ “Don’t leave me this way”. Surreal, in the Dennis Potter sense. Perfectly timed, mid-afternoon, during double French, with Miss Diaper...

Back to 2018…

As things turn wetter, thoughts turn to waterproof kit and we’ve also been putting some wallet friendly panniers, https://www.sevendaycyclist.com/oxford  mudguards https://www.sevendaycyclist.com/oxford-full-length-mudguard-kit  and tyres https://www.sevendaycyclist.com/vee-tire-co-easy-street-tyre  through their paces. Aimed at commuters, all three seem to offer a decent amount of bang, for modest buck.

  

The motor oil challenge continues and much as I expected. The 5w/40 remains very stoical but is collecting moderate amounts of gunk, which are being purged on a weekly basis before it becomes a drivetrain gobbling, grinding paste.  Stoicism aside, shifts are very slick and silent, I latterly dribbled a tiny drop into every link.

There’s no one formula, for every occasion, in my experience, hence I like to alternate between lubricants, depending on the season. Self-cleaning wax types are particularly appealing. Low friction, lower maintenance (save for more frequent reapplication).

Home brewed variants are also extremely cheap to make (once you’ve got the consistency right). However, some commentators forget that the time and materials invested in this, have a cost (not to mention, mess) implication, which pushes their real “start-up” cost considerably higher (although I fully appreciate this can be recouped quite quickly over time).

Similarly, if you are unsure of correct brewing procedure, buying stock products is much cheaper than an explosion. The sort, resulting in an open plan terrace, and strained neighbourly relations.   

One of the major advantages shared by motor oil, chainsaw oil and more traditional wet lubes, is the ability to drizzle on, wipe and scoot off. Perfect during late autumn and winter, where daylight is at a premium.

Speaking of forest fun, Sharon booked us a Forest Holidays break, in Nottingham last week. https://www.forestholidays.co.uk/?channel=ppc&gclid=Cj0KCQiAoo7gBRDuARIsANeJKUZ7A2ySyU__cEKkSfGO4ECVjym1pua6fPB-flh5RolooJh1ngRO6IYaAt14EALw_wcB&gclsrc=aw.ds

Despite some poor light, and inclement conditions, I managed a fair bit of mooching and captured a bit of trail action, for good measure.

En route up, I dropped my Shutter Precision PD8 dynohub wheel, with John Moss. Unfortunately, John says the hub is poorly, rendering spoke tensioning academic. Thankfully, Ison distribution www.ison-distribution.com have come to my rescue and will sort, under warrantee…
