Washed, Waxed & Revisited









 


250 very wet miles later and I wasn’t surprised by the subtle metal-on-metal tinkling of Ursula’s KMC chain. Closer inspection revealed some obvious orange patina along the inner side plates. Good for a wax lube in these contexts but confirmed my suspicions that while relatively stoical, the oil part wasn’t going to hinder corrosion in the way a similarly sophisticated petrochemical chain lube will.  


Given constant exposure to waterlogged, wet, greasy roads, Ursula was beginning to look a little sullied. Not sufficient for a sudsy bucket wash but needing more than a furniture polish blow-over. Hmm, let’s see how this Motoverde Waterless Wash & Wax bridges the gap I mused. This blend has carnauba wax, which is a popular choice in automotive formulas, thanks to its stoical, glossy results and it’s safe on all finishes.  


Given the relatively small surface areas, I’ve applied ours via a micro-fibre cloth, rather than trigger spray, to avoid wastage. Simply give the bottle a good shake, pour, apply sparingly to the frameset and components, leave a minute or two, then buff to a sheen with a fresh (ideally micro-fibre) cloth.  


Their main advantage over silicone-infused products (which add a great sheen and will lightly nourish elastomers, seals and other rubberised/ plastics) is that waxes of this type won’t attract dirt. Silicones leave a very slight film behind, which is helpful but rather like PTFE sprays encourage filmy stuff to become embedded in the surface. Again, welcome as a protective masking agent on working bikes/winter trainers with electroplated and polished aluminium alloys, since grime will stick and mothball them. 


Waterless cleaners are minimal mess, minimal faff and some, including Motoverde’s will keep UV, salts and similar corrosive elements at bay into the bargain. Obviously, waterless cleaners are for light to moderate grime. Cyclo cross style grot, like that adorning my fixed gear winter/trainer will require bike washes/warm buckets of wash n’ wax, sponges and brush (es).


250 miles in and I'm also pleasantly surprised by the Smanie GT saddle. 

 

137mm wouldn’t be a compatibility surprise on the Holdsworth and yes, a few millimetres shy of a designated ideal might make negligible difference but there is a fine line between something not fitting, not functioning correctly and indeed, failing. (Those seat collars being prime examples- 4nms, not a fraction more).  


Point of this preamble? Well, I wasn’t expecting it to work so well on Ursula-on and indeed off-road. One of the main attributes of the GT is that it’s designed to hold the rider at the most efficient point-for folks that like to get and stay in the zone, so not a shuffler's saddle.  


I’ve also noticed a slightly quicker cadence, though no loss of support to the ischial tuberoses (sit bones), let alone soreness/chafing. That said; Ursula and I also got along very well with The Selle Italia Sport Gel Flow FEC-Alloy saddle, which is relatively short (270mm) and narrow (140mm).  


FEC (lower rent hollow steel) rails put the weight up a bit too-330g, which is light, compared with a traditional leather saddle. even those with titanium rails, such as the Spa cycles Aire. This, loosely speaking, is a Brooks Swift homage which my derriere has spent many thousands of miles on.  


Another product that I’ve spent many miles with is Kinekt suspension Stem Kinekt Suspension Stem 90mm | cycling-not-racing (sevendaycyclist.com). It’s heavier than some and may be a little too reactive for some tastes, but the parallelogram design is well engineered, doesn’t change reach, or geometry and though minimal maintenance, is easy to work on/adjust when needed.  


Chains are something I keep a close eye on. Not to the point of becoming a bore, neurotic, or borderline obsessional, I’m talking a quick weekly inspection using the humble nickel-plated chain checker, which can be picked up for a few quid.  


Inspection and prompt replacement prevent more costly wear-rings, derailleurs and cassettes being the obvious casualties. These also need periodic inspection. As a rough n’ ready rule, I replace cassettes every third chain-at least on bikes in four seasons’ service.  

Chain whips are the most common means of wrestling the cassette into submission while freeing the lockring. Functional enough, Pedros Vise Grip changed my cassette-swapping life- an end to slippage, grazed knuckles and agricultural outpourings. One of those tools (along with my headset press) that I never loan.  


Then along came Feedback sports offering me their Cassette Pliers. These work to the same principle as the Pedros, so it’ll be interesting to see if they’re any different, dare I say, more refined. Pedros set the bar very highFeedback also has a rather nice three-in-one bottom bracket and lockring tool, which has the ends welded in situ, so the splined cassette/centre lock bit can’t get lost or come adrift.  


I don’t change cassettes too often (or disc rotors, for that matter), so the little cyclo does the job well enough. However, it can struggle a bit on stubborn, weathered examples... Ending on a different note, if you want to keep your carbon happy, Peaty’s Max Grip Carbon Assembly Paste Peaty’s Max Grip Carbon Assembly Paste | cycling-not-racing (sevendaycyclist.com) has proved an excellent default.

Bolts & More Boing










 For some reason, Ursula’s Cycles Berthoud Soulor Leather Saddle CYCLES BERTHOUD SOULOR LEATHER SADDLE | cycling-not-racing (sevendaycyclist.com) is disagreeing with me- shouldn't given the miles we’ve been doing over the past two years. However, I've never got along with Brooks iconic B17 either. Might be a short/pad incompatibility. Either way, I decided I’d switch in favour of this old-school Sell San Marco Concor Super Corsa Saddle. The Super Corsa was originally introduced in 1978 and arguably a more obvious choice for a retro road build. I’ve contemplated fitting it to the Teenage Dream 1991 ROAD BIKE REVAMP | cycling-not-racing (sevendaycyclist.com) on a few occasions but I’m strongly wedded to its Selle SMP Strike Plus.  

The Concor is surprisingly narrow too. 265 long and140mm (about 5.51 in) at the widest point, so we’ll see how we fare in the next few hundred miles. The hide’s colour is also a good fit with the Souma Leather bar tape. This also presented an ideal opportunity to re-grease the Kinekt 2.1KINEKT 2.1 SUSPENSION SEAT POST | cycling-not-racing (sevendaycyclist.com) cradle hardware.  Since we're talking contact points, here's my review of the Funkier Apiza Gents Elite Bib Shorts Funkier Apiza Gents Elite Bib Shorts | cycling-not-racing (sevendaycyclist.com) 


Given the heatwave, it was time to get some more miles in on the Holdsworth. The stem bolts I’d turned to as contingencies (having switched to the Star Fangled Nut and re-greased the Saturn Aheadset a few weeks back) were also extracted and replaced. The heads were completely chewed-I'd only snugged them to 5nm with a torque wrench and decent quality tool bit, which says something about their quality 


Replacements seem fine, but then, they’re the same as fitted to the fixed gear winter/trainer’s Redshift Sports Suspension Stem.  Several pre-dawn rides confirm everything is bang on and I’m making the most of the dry spell, it’ll be autumn and then winter, soon enough.  

 

Maybe the heat was addling my thought processes, but I’d even toyed with the idea of switching the Holdsworth’s Torus Titanium Stem TORUS TITANIUM STEM (sevendaycyclist.com), for the Kinekt Suspension stem KINEKT SUSPENSION STEM | cycling-not-racing (sevendaycyclist.com), but it's out of kilter with the bike’s build and purpose It also adds 150g or so to the build. Not massive and easily countered by switching to lighter inner tubes, possibly a lighter seat post. Arguably, other than experimenting, or possibly proving a point, there’s little to be gained and its time better spent elsewhere.  


After some deliberation, I switched the Kinekt to my fixed gear winter/trainer. Now, I have a soft spot for the Kinekt, having run it through December 2020. It’s very plush and refined, although I would still prefer a stiffer elastomer than those supplied. A moot point when in the cruising stance but aggressive, out of the saddle efforts-say when ascending (which is more common on the fixed), and I found it was a little too active.  


I’ll freely admit to being a fan of the old Girvin Flex stem. I had one of my (long gone) 1990 Kona Lava Dome (“Lotti” in case you wondered). Critics suggested the elastomer system was too whippy, but it curried favour with me. By the same token, suspension stems are considerably lighter and less mechanically complex than suspension forks.  


I’ve run hardtail XC mountain bikes for many years and was similarly fond of the Rock Shox Indy SL with air cartridges. These were a relatively expensive and unintended upgrade, having foolishly followed the “guidance” of someone claiming Castrol Red Rubber Grease was superior to Judy Butter and similar elastomer-specific products.  


Sure, it was cheaper but ruined the elastomers. I was racing at the time, so suspension forks were well worth the investment and added weight (especially since I was also riding plain gauge 7005 aluminium alloy frames between autumn 96 and autumn 99). Ok, so I’ve gone a little further along the suspension trajectory and memory lane than initially intended...    

 

Back on track, there are rumoured to be stems employing air shock technology, reckoned to be around the 300g mark but I haven’t seen any production models, at least on these shores. Anyhow, if anyone has an innovative design, they’d like reviewed, feel free to contact me directly. No sooner had I typed this last paragraph, a postal worker arrived, brandishing some lubes and degreasers from Green Oil. A welcome and unexpected surprise
