Forks Return...Winter’s Wrath Continues










 Lee Cooper returned the Holdsworth’s forks. I’m delighted with the steerer extension and ahead conversion. The eagle-eyed will note it’s a slightly different shade of blue, but I like the subtle contrast, so it’s staying. I’ve retrieved the XLC longer reach dual pivot calliper and then I’m ready to switch everything over, at my leisure- the Holdsworth is a sunny day’s plaything and presently enjoying seasonal hibernation. For now, they can sit in my office.  

The plan is just to whip the Woodman’s lower cup from the Acor carbon unit and transplant it to the steel fork. At that point, I’ll thoroughly inspect the cheap but cheerful Acor and decide whether to keep or euthanise. I’ve sold older, branded forks with 6061 steerers and carbon blades in the past. However, on balance, I’ve concluded it’s not worth the hassle, or risk this time.  

While on these missions, I also acquired another 1-inch Aheadset (an FSA) since these, or at least, decent-quality staples are getting trickier to find-at least at the right priceThe blue anodised finish is another shade of blue but again, aesthetically compatible with the existing livery.  

Famous last words, that’s the Holdworth’s revisions complete. I might port the Miche calliper over to the Teenage Dream as an upgrade to the budget but very serviceable Miche Performance unit but that can all wait- we’re slap bang in the middle of a stormy winter. 

 

The ice relented but was replaced by storm Isha. Milder temperatures induced a switch back to the Halo Spin Doctor and Shimano Alfine Dynohub Shimano Alfine UR700 Hub Dynamo | cycling-not-racing (sevendaycyclist.com) wheels shod with the Maxxis Ikon tyres Maxxis Ikon Tyres | cycling-not-racing (sevendaycyclist.com). I also decided then was time to retire Ursula’s KMC chain. I managed 750 miles before it nudged .7 on the chain checker. Typically, I’ll get 1100-1300 miles so this should give an idea of how wet and generally grotty the past few months have been.  

I have a love/hate relationship with magic links. On the one hand, they are very convenient (especially when you’ve the magic link pliers to hand. Note to self, must locate mine). Much of this arises from a lack of feeling in my index finger, which makes aligning the two parts fiddly-especially when it's bitterly cold. I manage, it's just a slower process 

While hunting the KMC magic link pliers, I rediscovered this Hyper Cracker cassette lockring tool. It basically turns the bike frame into a giant chain whip and allows roadside cassette removal, say when needing to replace a drive-side spoke mid-tour. Really nicely made and a pleasant resurrection. Wondered where that had got to.   

 

Given things had thawed, I headed out on the fixed for some faster-paced fun. Thick mud carpeted the roads, and I was pleasantly surprised by their grip through some seriously slippery, gloopy stretches. Not quite in cyclocross, or Paris Roubaix territory but not a great deal of tarmac.  Despite the low temperatures, these Castelli Entrata Thermal Bib Knickers are surprisingly comfortable Castelli Entrata Thermal Bib Knickers | cycling-not-racing (sevendaycyclist.com) 

  

As for the tugs, well, perhaps predictably, I’ve gone for another set of MKS NJS. Credit where it's due, the auction site specials were in fact of a decent quality. Problem being they were 10mm, which means they’d foul the chain. The non-drive side was a nice fit. In some respects, I’m annoyed- should’ve just gone for the MKS first time around but that’s the thing with auction sites, they’re a gamble. You can get an absolute bargain or buy cheap and buy twice. 

 

I’m sticking with the Weldtite Ceramic WELDTITE CERAMIC LUBE | cycling-not-racing (sevendaycyclist.com) for now-at least until something seasonally appropriate arrives for testing. As defaults go, there’s a lot in its favour. It’s relatively clean for a middleweight and doesn’t wash off come the first puddle. The advantage over a more traditional, gloopy wet lube is that while it won’t hold back hell n’ high water, it won’t become such an effective grinding paste when grit, salt, mud and other contaminant litters the landscape

Revisions










Chain and cassette replaced, I still had a good 250 miles or so to go before nearing anything like a conclusion regarding the Halo Fixed G hub and fat cog system. Wet, greasy lanes with waterlogged sections, mulched equine dung were perfect and rather welcome, given the mild February we’d been experiencing. A subtle “phantom” squeak permeated my serenity. Snugging the track nuts and 8mm crank bolts down proved the antidote.
This gold anodized Halo skewer presented itself, so I thought “why not”. Cured some very minor pad rub, which pipped up, when I was out of the saddle, and dancing up the climbs. Disc rotor was true, cables and callipers were correctly adjusted, and everything behaved impeccably on the workstand (doesn’t it always?).
Therefore, perhaps a tighter union at the dropouts…Niggle, and episodic tinkle muted.  The passport anti rust single speed chain continues to do its thing silently, and the galvanised surface does an excellent job of retaining lubricant.
I was a little surprised to discover some orange taint. Especially since Weldtite TF2 extreme wet lube https://www.sevendaycyclist.com/weldtite-tf2-extreme-wet-chain-lubr  is one of the most tenacious (albeit not the cleanest) wet lubes I’ve used to date.  
The watery corrosion vanished, upon contact with a clean rag. Some Squirt chain lube arrived for testing, so I treated the transmission to some Green Oil chain degreaser jelly, as part of a sudsy bucket spruce-up. Talking of which, Steve’s been putting Silkolene wash off, to the test https://www.sevendaycyclist.com/silkolene-wash-off
A reminder that Spring can still prove very wet and mucky, so I’ll leave the KMC dressed in its factory lube. Once that’s thinning, I’ll swap to the Squirt. Dressing appropriately for the changeable conditions, is another challenge.  Thankfully, softshell jerseys and ¾ lengths with water repelling top layers plug the gap.
Early morning outings are still quite chill too. I’ve always found this very refreshing and for the time being, I’m still sporting a “Belgian style” cap beneath my lid and Oxford Bright 4.0 gloves https://www.sevendaycyclist.com/oxford-1 . I pack a buff and the Oxford bright waterproof cycle gloves 3.0 https://www.sevendaycyclist.com/oxford-bright-3-0-gloves  on longer rides, when temperatures can climb into the low teens.   
Full length guards make a world of difference, keeping bike and rider, presentable. Cue the Univega and putting miles on the Selle Italia Sport Gel Flow FEC-Alloy saddle.
Thus far, its proving music to one’s derriere, whether I’ve been cruising along the asphalt, or tackling more technical terrain. Soft, yet supportive, which can be a very difficult balance to strike.
The relatively narrow profile is also very conducive to fast tempos, although I’m generally cruising along at 85-90rpm. Another intermittent phantom squeak (traced to the M45’s jockey wheels), prompted me to carry a small dropper bottle of simple lube.
Saddles and pedals are the first components I replace, on off the peg bikes (purchased, rather than tested). The Inbred, fitted to my stock MKII Ilpompino, was a notable exception. It eventually migrated to my MTB based crosser, with similarly pleasing results.
That had 46cm road drops, which were up to the job in the “Use what you got” tradition. It was On-One Midge drops, that really turned me on to the big, swoopy sort. The 25.4mm versions were a bit whippy but the 31.8 firmed things up a treat.
WTB Mountain drop bars are another firm favourite of mine. Especially for a rough stuff tourer, or tagalong/trailer tug, although to my knowledge, they’re no longer made. No surprise then, that I was generally impressed by Soma Fabrications Condor https://www.sevendaycyclist.com/soma .
Something of a talking point, the shape generally suited me. However, the original pastern had some drawbacks. Soma have revised the shape. The MK2’s top sections are also straighter, allowing easy fitment/alignment of lights, and more hand space. That said; drops and hoods, are my go-to defaults.
Speaking of revision, it’s been a good few years since I towed Joshua behind, on the tagalong. He turned 16 this week and will be sitting his GCSEs this summer. That chapter of my life remains ingrained, almost thirty years hence.
Provisional places on courses at FE college. The opportunity to study subjects I was interested in, focused my mind. Riding kept me sane in between revision, exams and anxiously awaiting results. Whether examinations, is the best means of assessing knowledge, or competence, is somewhat debateable.
Nonetheless, undertaking previous papers, to strict exam conditions, will hone these skills, and is, like time trialling-the race of truth. It will reveal where your weaknesses, and gaps in your knowledge lie. Everyone’s different but don’t sit more than two “mocks” per day, tops.
Remain structured, it’s easy to kid yourself your knowledge is better than it really is. Or, at the other extreme, hammer yourself into the ground. Papers aside, set revision in two-hour blocks, and slot in regular food and sanity breaks.

Pads, Cassetes, Cables & Chains








Winter can chomp through consumables, at an alarming rate. Pads are no exception and I’d bought replacements, knowing the time was edging closer. Fade struck, along a regularly traversed 1in7. Decision made. Pads stripped and replaced within minutes of returning home.
These patterns lasted a year, or so. Fixed relies less on mechanical braking, thus usefully extending pad and related component life. Provided you’re not living in a particularly hilly region, of course. I continue to be delighted by the Halo Fixed-G rear hub. Perfect chainline also ensures a nigh on silent transmission. Acceleration feels tangibly brisker, too. I’ve reached my conclusions regarding the Tioga City Slicker tyres https://www.sevendaycyclist.com/tioga-city-slicker-tyres  
Richard Peace has been putting the Carrera cross city folding bike through its paces  https://www.sevendaycyclist.com/carrera-crosscity-folding-electric-
Pad changing presented an obvious opportunity to give the bike a deeper clean, than usual.  The Velo 21 dirty weekend pre-wash did a decent job. It’s a subtle formula that doesn’t foam, or anything visually exciting. Science suggests the surfactants are doing the business. Eating into the grime, rather than just foaming on the surface.
Suffice to say, it romped through organic grot and slurry, without needing to agitate. Even petrochemical based spatter slithered away, left marinating for five minutes and then rinsed. These Soma Fabrications Condor II shallow drop bar also arrived this week, so I wasted no time fitting them.  
Elsewhere, having averted potential castration, my Univega’s cassette was resembling one of those “fat balls” supposedly breeding in our sewer systems. An obvious candidate for Velo21 degreaser.
Chain, cassette, jockey wheels and ring came up quite nicely too. Not without a fair bit of elbow grease. It’s worth noting that Stealth, is a very stoical ceramic. I’ll need to see how it works on less tenacious lubes, before passing appropriate, fair comment.
I also checked the chain’s health, using this digital chain checker. Budget analogue units are dirt cheap, accurate enough too. However, I prefer the pin-point, in a glance confirmation. Chains don’t stretch, they wear. Consign to the bin, once wear measures 0.8mm.     
Time spent undertaking regular inspections and preventative maintenance is priceless. Aside from extending the life of expensive components, I’d rather be out, enjoying the miles than fixing stuff by the road/trailside. Let alone the long walk home. 
This housekeeping also proved the ideal opportunity to fit the Easton EVA wrap and swap back to the Schwalbe Marathon Mondial https://www.sevendaycyclist.com/schwalbe-marathon-mondial-tyres , now the threat of ice, has greatly diminished. https://www.sevendaycyclist.com/after-the-gritters-went-home
Bored with Brexit, red top tabloids have now fixated on extreme weather. Coastal flooding now tops the agenda.  
After some casual, late night trawling, I came across an Alivio rear mech, to replace the long serving Microshift M45. Crucially it was of a higher spec, and at the right price. I’ve stripped, cleaned and inspected the M45 and there’s surprisingly little slop.
I changed the cable and closer inspection revealed the SRAM chain was fit for the knackers’ yard, cassette not far behind (though thankfully, I already had an 11-28) so retired both.
Worth buying a stock of both, if you do big mileages and/or ride in harsh conditions. However, as I’ve said before, there’s a fine line between sensible stock-piling and hoarding.
Cassette lock-rings can become very stubborn, even when they’ve been given a lick of stiff grease. The 11-30 Sram was no exception, benefitting from a quick blast of penetrant spray.
11-28 tooth electroplated Sram replacement on the freehub body and lock ring greased, I torqued it to 40nms, reinstated the wheel, then cut and fitted the new chain. I ordered two, so there’s one on tap, when the chain checker chimes 0.8mm.
While the other 9spd components are in solid shape, I’ll stick to this grade of rear mech and consumables. Unless I’m presented with an interplanetary (hub gear) system, I’ll probably upgrade to ten speed. An Octalink crankset, Deore mech and Sun Race brifters seem good options. The production Alpina 506’s factory specification, was a mix of Shimano LX and XT.
At present, it’s an eclectic mix of Ultegra, Deore, 105 (equivalent) and some slightly lower end but extremely serviceable parts. Components that make it go and stop in excellent proportion. I’m a constant tinkerer, and some would say, contrary figure.  Who knows what will follow…

The trials and tribulations of the terrible triple…


Journeying through the mists of time, I recall a misspent youth cum school career with afternoons' spent sneakily pouring over the cycling press of that era. Enticed away from teachers’ dull and seemingly irrelevant pontification about their wife’s IUD, the world of work etc by the romance of faraway lands and their people. Obviously, this experience was aboard a heavily laden, ultra refined expedition tourer complete with top drawer tubing and cutting edge, mtb drivetrains with enough gears to ride up, down and along the Great Wall of China. Panniers bulged with magnesium bodied film SLR camera, lenses, rolls and rolls of film, pens and notebooks all documenting this adventure for press and publisher. Paragraphs from the buyers’ guides were quick to point out that keeping triple configurations in consistently rude year round health was something of a chore. Fast-forward twenty-four years and several configurations later; I’m inclined to agree. The most recent dig in the ribs came courtesy of the Sun Race chain’s unexpected breakage. Thoughtfully (In common with recently documented punctures) it had the good grace to expire at journey’s end, some hundred metres from my front door-not the back of beyond. Much soul searching gave way to opportunity. Time to strip, replace and perhaps reconfigure the tubby tourer’s drivetrain.


For starters I’ve introduced a New Shimano pattern nickel plated BBB chain and cassette to see how these shape up and a quick tweak of the front mech cable has righted the temperamental will it, won’t it clamber aboard the big ring. Continuing the health check suggests the rear LX is in early middle age, so aside from a cursory turn of the B tension screw and some very judicious lubrication cable and pivot points, it’ll remain in gainful employment. I am thinking of retiring the Ultegra bar cons in favour of “Brifters”. Shimano’s venerable Sora seem prime candidates since I don’t run linear pulls and received wisdom suggests in daily service, their operational lives are around the four, maybe five year mark.

My MTB based crosser cum working bike was initially conceived with Modolo Morphus units that were tuneable for either Shimano or Campagnolo seven/eight speed configurations. Bought as a bundle (bars, levers & wrap) for sixty odd quid, modulation and feel were excellent, although shifts clunky by modern standards even with an LX mech STX crankset and 11-19 straight through block. Brifters have the obvious vulnerabilities in the event of a nasty tumble but since my purebred crosser manages just fine I’m looking forward to introducing a set of suitable Microshift. In common with similar emergent brands, performance and pricing are ear- to- ear grin impressive on a scale reminiscent of Kawasaki and Honda’s impact upon the all but defunct British motorcycle industry back in the mid1970s.
There’s two variants-double and triple and I’m wondering how the left lever will cope with the 42, 32,22 Alivio rings since Microshift recommends 52,42,30. In practice and with a smattering of blind faith I’m hoping some divine influence will look kindly upon this here world-weary journo and a’la Carte drivetrain. Enforced leave from variable gears, coupled with the picture postcard spring weather presented the ideal opportunity for long, steady, reflective outings aboard the Ilpompino. I could pontificate ad pretentious nauseam about the Zen-like qualities of fixed and its ability to lift one into a meditative state but this is all deeply passé’ hipster-speak and there’s been no requirement on my part to appease this particular mindset, whether it be cycling or unrelated politic. Cliché’ might be truth in a processed and deeply over-simplistic form but its an irritant and something to be avoided at all costs.

Both book projects continue to gather momentum, albeit at different rates but there’s no room for complacency. My approach varies from a relentless need for progression during the week and being in the zone can mean simply typing during the day, editing at night or alternating between business emails, regular copy and book depending on which is most productive at that moment in time. Having organised drivetrain consumerables, I found myself galvanised into writing a related feature, which In turn lead to a thousand words or so invested in the cycling book and some serendipitous conversation with a distributor offering further inroads into the other book. Time waits for no man (sic) no favours has he.
