Meltdowns & Recoveries















A much-publicised heatwave hit on Monday 17th July (although arguably crept in over the weekend) meaning that my dawn outings were mandatory if I wanted any saddle time. 35-36 degrees is very typical for many Mediterranean countries, and I've experienced 37 plus in more tropical climes, but the UK isn’t geared up for extremes. For good reasons, dogs were either walked at 5ish or not at all, to protect their feet from blistering, not to mention heat exhaustion.

 

Signs had cropped up, warning of loose chippings along the lanes but I reasoned, given the heat, folks weren’t going to be laying these, or indeed tarmac. There’s no statutory maximum legal temperature before people can cease, or decline to work, in the UK. Given the present trajectory, the current administration would simply revoke it- on their much publicised “bonfire” of legislation.  


I found some new bridlepath to explore, which also cemented my feelings regarding Ursula’s saddle change.  


The Super Corsa was an inspired move and as these outings confirmed, surprisingly agreeable sans asphalt, too. I was pleasantly surprised to discover tarmac hadn’t turned to treacle (although some farm vehicles had left their calling card). Even at these times, the temperature was rising fast-from 11 to 19 degrees within an hour, 19 and 26 degrees, on subsequent mornings. Tarmac’s top layer begins to assume a softer state at 51 degrees but allowing for other factors, possible when the air temperature hits 25 degrees.   


Acceleration brought surprisingly cool, moist breeze, which was welcome and encouraged a faster than usual tempo. The Kask Protone Icon helmet also came into its own, rushing cooling air through my scalp. However, an oppressive heat was certainly promising. A muntjac deer pulled alongside, barking in a crude challenge, so we hustled along, rivaling each other for half a mile, before it exited right, into the undergrowth. 


Depending on mood and conditions, I generally alternate between Ursula and fixed gear winter/trainer.  I tweaked the latter’s chain tension while checking the tyre pressures and this ultimately resulted in a switch to the Halo White Line Classic & Shutter Precision PD8 HALO CLASSIC RIM & SHUTTER PRECISION DYNOHUB DISC WHEEL BUILD (sevendaycyclist.com). This also coincided with the security skewer’s implosion. I was torquing it to 10nms, when it sheared. Thankfully, I had a lightweight Halo skewer, so just switched.   


I’d recently switched the fixed’s stem, returning to the Kinekt which employs a very progressive spring/elastomer configuration. However, as I recall from testing, even with the stiffest spring, there’s too much travel for my tastes, resulting in a disconcerting knocking on the rebound.


A quick email to Evan at Cirrus cycles KINEKT Active Suspension Seatpost and Stem – KINEKT Store (cirruscycles.com) advised they’d produced a stiffer, aftermarket option and were happy to send me one. I didn’t need a second invitation. I also wanted to avoid delays, given the potential customs nightmare, which is looming in October.  


What are you spaffing about, Stenning? Well, on the present trajectory, the old CHIEF system is due to be decommissioned at September’s close, replaced by a CDS system, which appears to have been rushed and full of bugs. At present, pretty much everything is being waved through (hence goods are arriving quicker) and ample potential for smuggling.  


August onwards is the most active point of trading, whereas it bottoms out, come January. The other question is whether traders believe the new system will be rolled out and will migrate accordingly. This also affects imports I.e., goods coming into the UK. Shortages of produce and materials, including foodstuffs, will mean higher prices and grave consequences for many.    


Ending on a happier note, Carbon Cycles has graciously agreed to send me a carbon fork (aluminium alloy steerer) for testing. It’s designed for 26-inch MTB, which is in theory, an excellent candidate for older mountain bikes reinvented as gravel builds and/or those looking to trim the fat. At 918g (uncut) it’s a good bit lighter than the otherwise loveable 4130 “school chair” Cro-Moly pair, resurrected with the disc brake upgrade and will serve as default spares.  


Carbon Cycles set a suggested rider weight limit of 97.5 kilos (215lbs), so no problems there. I will be putting some Helicopter tape around the legs (Zefal Skin Armor Roll ZEFAL SKIN ARMOR ROLL | cycling-not-racing (sevendaycyclist.com)  is a firm favourite of mine) to protect against cable tie bite and cable rub. Otherwise, no modifications, and I will continue to employ the Gusset Unilock, since it offers more security than the humble Star Fangled Nut.  Right, I'll leave you with my review of the Momum MIC Dry Momum Mic Dry Oil Lube | cycling-not-racing (sevendaycyclist.com)

Cantering Along



Another 120 miles on my tubby tourer, pleased with the recent revisions, I decided it was time to dial in the Genetic CX cantilevers. There was a little too much lever travel, for my tastes. Thankfully, they’re much easier to hone, than the otherwise impressive IRD CAFAM2. Pull cable and straddle wires through a few mm, tweak balance screws-Result!
Switched to The Muc-Off Dry Lube, since opportunity presented. A freshly cleaned and lubricated chain always makes the drivetrain feel that bit fresher. However, 100 miles or so later, I'm increasingly forming the opinion that friction is lower than the Zefal Pro Dry Chain Lube https://www.sevendaycyclist.com/zefal-pro-dry-lube and Finish Line Dry lubes https://www.sevendaycyclist.com/finish-line-dry-bike-lube  which is going some.  
Shifting feels almost instantaneous, in both directions across the block, even under load. The pronounced lack of friction just encouraged me to increase my temp. I’ve also concluded gearing is bang on, for the riding contexts intended.
Admittedly, I could go slightly lower, for heavier trailer loads, but for time being I’ll leave be. Durability is another consideration (especially given the Muc-Off Dry Lube’s relatively long curing period).
However, I’ve gone past the 160-mile stage without any hint of waning. In common with some wax formulas, several days at 23-28 degrees, and its assumed that fluid consistency. Lubricant has seeped deep within the chain, and a filmy, residual layer is clinging to the cassette. It’s also quite tacky to touch, though transfer to fingers/clothing hasn’t proved overly problematic, thus far.
For some folks, the lube debate is binary i.e. if you’re riding in wet/changeable weather, stick to a wet formula. Dry, for arid, dusty conditions. However, given the UK’s notoriously changeable climate, I like something that can bridge the gap, resisting those unpredictable showery periods, without attracting a gungy beard. 
That said and testing aside; chances are you’ll find my chains running a stoical wet formula, such as Weldtite TF2 Extreme wet chain lube https://www.sevendaycyclist.com/weldtite-tf2-extreme-wet-chain-lubr  or, if I want to keep maintenance times down, something like SKS lube your chain, which locks the grot within the top layer. https://www.sevendaycyclist.com/sks-lube-your-chain
This might look unsightly but is “embalming” the chain. Crap eventually flakes away in chunks, leaving only a layer of lubricant behind.  Here’s an overview to lubes, if you’re new to riding, or want to explore the best option(s), for you. https://www.sevendaycyclist.com/blank-ao363
Elsewhere, I’m also warming to the Oxford Contour flow saddle. 120 mixed terrain miles in, the relatively narrow profile and sensibly proportioned padding density are proving a winner for my derriere. I was slightly surprised to discover the rails are a solid steel, which would probably explain the weight differential, compared with those sporting hollow Cro-moly. 
4130 is common at this price point too, and my preference.
Is it a deal breaker? Not necessarily, why bemoan a few grams, if the saddle fits your shape and goes unnoticed, in the most positive sense. Will give it another 250 miles before reaching a conclusive verdict, mind.
