Road to Christmas Recovery








I was suddenly struck by the seemingly inevitable and unavoidable seasonal Lurgi. One that left me bedridden for the best part of two days and asleep for 18 hours straight. I’d struggled to remain alert for 6 hours and managed 75% of a draft alongside some other generic admin. Sabre Tooth Man-Flu is a force to be reckoned with.  

Retrospectively I’d felt it charging full force on Sunday when I was switching wheels and giving the fixed gear winter/trainer a seriously good sudsy bucket clean. Neighbour had struck up conversation, while affixing Christmas lights to their wooden fascia and I was struggling to maintain a decent tempo of routine work and response.  

Night terrors are another obvious sign for me. There are people my rational mind knows I could not help and for the most part, their deaths were beyond my control, but the world and human experience are not necessarily rational. Sometimes, during these nightmares, I will meet the figures at the end of a long tunnel. Other times, their decomposing entities can be sat at the foot of my bed, seemingly begging my attention. Sometimes they are benevolent and kind, other times vengeful and malevolent. Not where we’ve been and done but what we do with these experiences, I guess.  

Two days later and I was back in the saddle- the fixed gear winter/trainer’s to be precise. This proved a little “previous” and I was struggling to move. For context, I slept 18 hours, during the first phase of this germ fest and was fooled into feeling better. Predictably in retrospect, I succumbed to a second helping. One synonymous with sinus headaches and similar pain. I ultimately reached for the paracetamol and lemon mix, which seemed to loosen the mucus floodgates and the intense pressure that dogged my ability to function. Sometimes enforced rest is what’s needed.  

I’m sticking with the Halo Aerotrack wheel and 15-tooth Ti sprocket, which with the 35mm CST Expedium and 42 tooth 165mm Genetic Tibia cranks translates as 76.1-inch gear. Some would suggest a little lower-72 maybe, but in practice, I’m not spinning out, or indeed, struggling to winch myself up the climbs 

Saddleback, Feedback Sports UK importer graciously sent me the brands’ Reflex Torque Wrench. Ita a mini torque wrench, designed for mid-ride adjustments-adjusting saddle tight, tightening a slipping stem bolt etc. 5nm is the maximum, too low for things like Shimano Hollowtech II cranks, so you’ll still want to carry a traditional multi-tool (although you should anyhow, since torque wrenches are only designed for assembly).  

Prevents unintentional damage of carbon fibre components and indeed, aluminium alloy components. Exceed the 5nm recommended on a seat collar bolt at your peril- I’ve seen the bolts snap/ shear clean off. Not what you’d want 20 miles from base.       Last bucket wash, I’d gone for a proper drivetrain clean and opted for the Zefal Extra Wet Nano Ceramic Chain Lube ZEFAL EXTRA WET NANO CERAMIC CHAIN LUBE | cycling-not-racing (sevendaycyclist.com)  (a) It was to hand (b) I’ve found it stays put and requires negligible time to cure.  

Ursula’s sticking with the Silca Secret Formula Chain Lube. Was relieved to get a call from Mick Madgett saying he’d replaced the Halo Spin Doctor’s Freehub. Upon collection, conversation turned to the hub’s internal composition and specialist tooling e.g. circlips.  

Apparently not. However, it took two of them to release the defunct freehub-knew there was a reason I outsourced that job! I put a lick of Wolf Tooth Grease on the free hub and cassette lockring and spun everything back together- tyre too. Will give the XT/Ryde pairing a few runs for the time being. They’ve also got the spikes on, which may come in handy, depending how conditions turn in the coming weeks.  

Regardless of how wintry the lanes have been, the Shimano MW501 have kept my feet dry and very temperate, the sole offering plenty of grip on slippery stuff and generally improving my riding experience through these dark December days.  

The heel cup and nimbler feel means they’re quickly becoming my favourites. I was very endeared to a pair of Lake, which lasted many years. However, the Shimano’s fit feels closer to that of a cyclocross/gravel shoe than a traditional mtb bootie, which for me, is more agreeable.  

The Madison Roam 2 jacket is also proving a well-conceived garment for not a lot of money. Decent fit, sensible pockets, useable hood and Velcro cuffs for a convincing seal against the elements. I prefer removable hoods but thus far, the Roam’s hasn’t made a nuisance of itself, when not required. On that note, I’ll leave you with an overview of clothing for the cooler, wetter months...WINTER WONDERLAND TWO (sevendaycyclist.com)

Temptations & Demons Purged











I’ve never been a spendthrift. Sure, I’ve enjoyed the odd splurge now and then. However, this tends to be when I’ve really wanted, or needed something. The fixed gear winter/trainer’s V2 frameset being a case in point. I’d been wanting one since 2003 but new parenthood, bills and related expenditure put this firmly on the back burner. I finally bought one (at a very compassionate price) for Christmas two years later.  


Made from in-house 4130 Cro-Moly and complete with matching fork, it was hardly exotic, or an expensive purchase but crucially responsive and engaging to ride. Fast forward 18 years and nothing remains of the original build, not so much as a spacer. The V4, though very worthy, and featuring more traditional (some would say better) seat stays failed to capture my imagination.  


A few years in the wilderness, the frameset has reemerged, (albeit with some obvious developments) as the Mulo. Back is the wishbone rear triangle and the blue livery, but a much beefier head tube and more refined dropouts. Theoretically, the head tube’s size and profile mean a bigger weld platform and bigger bearings, translating in a stronger, more responsive front end but without being unduly harsh.  


The Mulu has scope for 43mm (about 1.69 in) wide tyres too, compared with the V2’s 35mm limit. Now, you’d be forgiven for thinking I’d talked myself into indulging. My bike boner was indeed, leading me in that direction. However, when other costs were factored into the equation, the upgrades/improvements didn’t justify spending £435 (frame, fork and Aheadset). Besides, there was also the emotional bond between me and the V2 after all these years, many miles, and rider-centric evolutions.  


Instead, I decided it was time to get testing the eXotic Carbon Titanium Seat post. 350mm long, titanium refers to the cradle hardware and our 27.2 tip the scales at a feathery 173g. I’ve gone for the Selle Royal Respiro Sport Saddle since it was handy and generally very compatible with my derriere. (264g, on account of the magnesium rails but only 7g over the Selle Italia Turbomatic Gel Flow Team Saddle, which has carbon). Yes, I spotted the slightly upward tilt and levelled accordingly.  


Again, the fixed gear winter trainer is hosting-I'm leaving the Holdsworth’s Crank Brothers Cobalt3 and BBB Razer combo in situ. However, I did slip the post out and gave it a lick of grease, since I was there.   


The last thing you want to introduce carbon to, is grease.  

Having whipped the Genetic Syngenic TEST & REVIEW: GENETIC SYNGENIC SEATPOST (sevendaycyclist.com) out, I cleaned the seat tube with a clean rag dipped in solvent and added some gripper paste to the eXotic post. For the uninitiated, gripper pastes are designed to grip the post (or other part) reducing the torque required (and therefore, potential damage to the post/stem etc).  


Most brands seem to work just fine, although I’m personally fond of Muc Off MUC-OFF CARBON GRIPPER PASTE (sevendaycyclist.com) and more recently, Peaty’s Max Grip Carbon Assembly Paste Peaty’s Max Grip Carbon Assembly Paste | cycling-not-racing (sevendaycyclist.com) 


Formative impressions of the eXotic post are favourable, its light and gives that familiar buzz taming ripple across washboard tarmac. No creaking from the titanium hardware, either, which was similarly welcome, although during the first few outings, I’ve been keen to check they’re snugged tight.  


Talking of snugging things tight, while giving Ursula a well-deserved wash, I discovered some minor play in the bottom bracket region. Easily purged in a matter of minutes. For the uninitiated or unfamiliar, slacken the left-hand crank arm, turn the preload clockwise-fractionally using a 10mm Allen key, then tightening the 5mm Allen bolts to 14nms.  


The prevalence of carbon composites and other materials mean the torque wrench is as essential as the floor pump and excellent quality pressure gauge for home mechanics. Indeed, I’m coming to the point where compact torque wrenches are preferable for mid ride fettling and mechanicals. Most, including budget models, are perfectly accurate and pleasant to use. However, they’re also precision instruments.  


Always release the tension I.e., dial them out to zero after use and don’t drop them. Some sound an audible “click” when the correct tension is achieved, some go limp, others do both. Either way, do not go beyond this. I’ve lost count of the times when I’ve heard automotive fitters go three clicks past “just to be sure”. Not people I’d want working on my vehicle. 

  

This M-Part Torque wrench has served me well for over a decade. It’s a sub £60 model, which is intuitive to use and has an operating range between 2 and 15nms, which caters for a good spread of bicycle-related applications. JIS square taper and Octalink crank bolts, Hollowtech II bottom brackets, and cassette lockrings are obvious exceptions.


Weldtite has also sent me their Cyclo model, which casts the net a little wider range-wise (2-24nms). It also measures foot-pounds, extending its horizons to other applications, which may roll the dice in its favour.  


Some generic auction site tools range from 5nms upwards, which might be fine for stem and seat collar binder bolts upwards but rules out more delicate fasteners including bottle cages, mudguard, and carrier mounts, which are typically 2nms, or so. You pays your money....On that note, I'll close with my review of the Maxxis Refuse TR tyres MAXXIS REFUSE TR FOLDING TYRE | cycling-not-racing (sevendaycyclist.com)
