Too Much Pressure







Despite the best efforts of Jacob Rees Mogg, SKS in Germany (those people responsible for arguably the finest full length, chrome plastic mudguards) were able to get this Air-X-Plorer Digi 10.1 Track Pump to my door in a matter of weeks.  


However, unless the UK rejoins the customs union shortly, this may not be so easy later down the line. Against this backdrop, I snapped up some SKS guards that were going seriously cheap (along with some other little sundries, while I was there and to justify the flat-fee postage).  It shouldn’t be inferred that Ursula’s SKS Blumels Shiny SKS BLUEMELS SHINY MUDGUARDS | cycling, but not ususally racing (sevendaycyclist.com) are in anything but rude health. However, at that price, I’d be a fool not to, and save ‘em for a rainy day.  


In a fit of pique, I decided to bolt some Shimano MT cleats to these Shimano touring shoes, which I resurrected after several years on the subs bench.  Why? Well, I was curious to see how far soles and other tech have come along in the last 12 years, or so. Multi Release Cleats (denoted by an M) are, as their name implies are designed to allow disengagement from multiple angles.  


Traditional models, such as Shimano SM- SH51 are designed to release ONLY when the heel is moved outward. The multiple release can disengage in any direction, including tugging upward. I’ve not had any issues with unwanted release when gently pulling up on the pedals-even with the pedal spring tension set to minimum. Newbies might sound the most obvious audience but aside from being generally convenient, riders with less strength in their legs, or joints would also reap benefits.  


I’m still loving the Oxford Venture Jacket OXFORD VENTURE JACKET | cycling-not-racing (sevendaycyclist.com)- its lightweight, easily packable and great for those morning’s where it may not be raining, but intermittent blustery winds have an edge to them.  However, I decided it was time to add a zipper tag to the breast pocket, for easier access.  Retrieving my superzoom compact camera was becoming an awkward fumble and wasn’t going to have a happy ending.   


Drier weather has meant more weekend miles on the Teenage Dream. The long bank holiday weekend was perfect for this and hiking the saddle height by those few milimetres was an inspired move. However, I had just switched to this Eclipse Road 25 Tube inner tube, when I discovered a disconcerting bulge in the Vee Tire Co Rain Runner Clincher Tyre. 

 

Closer inspection confirmed it needed pensioning off. Fortunately, I had another 25mm Freedom Thick Slick resting quietly in a corner, so performed the switch. Eclipse tube safely instated; I was suitably impressed by the speed and ease at which the SKS delivered 110psi (the Thick Slick’s maximum pressure).  


Staying with rubber, here’s my review of the Vittoria Evolution Road Bike Tyres Vittoria Evolution Road Bike Tyre | cycling-not-racing (sevendaycyclist.com). Both machines are running the Momum MIC Wax chain lube, which has held up surprisingly well by wax standards and along some very wet roads and yes, heavy rain, too. 440 mixed terrain, mixed weather miles before any telltale taint and tinkling.  


Incidentally, this can be replenished, without needing to strip the residual. Shake, drizzle in, leave to assume a glazed lacquer-like state, then scoot-off. On this basis, it’s looking a very viable choice for tourists (especially given there’s a 15ml option). Seems to be working rather well on cleat mechanisms too. 


Talking of scooting off, Steve’s been testing these 360 Dry Blue Ankle socks 360DRY BLUE ANKLE SOCKS | cycling-not-racing (sevendaycyclist.com) 


Though the two-wheeled fleet has a decent amount of waxy internal preserve sloshing around their inner sanctum, I like to have plenty lying around-especially to treat the KA and Micra underbody, so picked up a bargain candle, while doing the weekly Tour de Supermarche’ and ordered in two litres of solvent online, benefitting from the economies of scale.

Bum Steer AKA Its Too Tight, Or Its Too Slack..










 I had a model cancel a shoot, which is annoying but comes with the territory. This presented an ideal opportunity to investigate some issues with my fixed gear winter/trainer’s recently replaced Aheadset.  

I’d pensioned off the long serving FSA, which had served faithfully for five fairly hard years. The lower race employed a cartridge bearing, the upper traditional balls, which keeps costs down, but I fancied something a little more refined, hence the Stronglight.  


However, despite having everything correctly aligned, it wouldn’t adjust properly. Removing slop meant tightening bearings to the point the bars would barely turn. Something was clearly very wrong, and I wondered if this was indicative of a more serious fork steerer issue.   


A full strip and diagnostic session followed. I dismissed the Gusset Uni-Lock Headlock, inspected the fork steerer, paying particular attention to the crown area and went the SFN (Star Fangled Nut) route.  


I then dismantled the headset and found while new, it was a “Franksenset”. One cobbled together from two superficially identical but ultimately, incompatible models (which in retrospect, explains the issues and why it was so cheap). The compression ring being a case in point. Given it was boxed and sealed, I had no reason to think anything was "off".  


Decision made. No sense attempting silk purse from sow’s ear. Might as well start again...The cartridge bearings would be useful but otherwise, I put it down to experience. Thankfully, I found a complete, sealed Olite I’d bought a while back. This also proved an ideal opportunity to use a tube of Park PPL grease that was splitting along the seams.  


Lashings of the tenacious green goo delivered to the cups and races-buttery smooth. New stem bolts, (since the Redshift Sports Shockstop Suspension Stem TEST & REVIEW REDSHIFT SPORTS SHOCKSTOP SUSPENSION STEM (sevendaycyclist.com)’s  were getting a little chewed) some fresh thread lock on the disc caliper mount hardware, some spacer-switching... 


Time consuming but formative checks confirmed things were broadly right, so I fine-tuned the preload and snugged the stem bolts to 5nms. Cane Creek SC5 CANE CREEK V BRAKE DROP BAR LEVERS | cycling-not-racing (sevendaycyclist.com)lever engaged and several, neurotic rockings later, I couldn’t trace any slop, so tethered the K-Lite dynamo K LITE BIKEPACKER ULTRA DYNAMO LIGHT | cycling-not-racing (sevendaycyclist.com) cable to the Kinesis fork leg.  


Of course, I wasn't done there!  


Tyres inflated; pedals switched in favour of the Shimano XT, chain tension tweaked and finally, Motoverde PTFE Chain LubeMotoverde PTFE Chain Lube | cycling-not-racing (sevendaycyclist.com) stripped in favour of this Momum Mic Dry Lube. I finished by giving the frameset a light waxing, buffing with a micro fibre cloth, then popped it away.  


There’s a fine line between staying with something until you’ve got it sussed (and sorted) and quitting while ahead.  Sure enough, the following morning’s shakedown ride confirmed the bearings were a little too snug.  

 

Slackening the stem bolts, I loosened the pre-load by 16th turn, did the rocking back and forth test, then tightened the stem bolts to 5nms.  Cue loud (internal) cheer-it was 5.50am and I didn’t think my neighbours would be so appreciative, dare I say empathetic.  When it comes to bearings, headset and bottom brackets, I preside durability and weather sealing above weight and indeed price. Needle bearing models that displace loads were particular favourites 


The Teenage Dream was originally built, (back in ‘91) with a Primax unit featuring these, which might seem strange given needle roller bearing models were a tourists’ choice and said machine was a sunny days, pared to the essential's plaything...I’ve run them up to very high mileages on traditional touring lorries but they’re also a good bet for bikes that regularly lug trailers and indeed, tag-alongs.  


Decent waterproof greases, including the Park, or White Lightning Crystal TESTED : WHITE LIGHTNING CRYSTAL GREASE (sevendaycyclist.com) certainly help extend service intervals, without shortening component life. Mudguards (Fenders) also make a big difference but if this isn’t an option for you, make a boot from old inner tube to protect the lower race.  


Obviously, being butyl go for a synthetic grease, rather than the old school lithium, or PTFE infused blends, since these will rot rubber-another consideration if headsets employ rubber seals.  Green Oil Eco Grease TWELVE MONTH TEST: GREEN OIL ECO GREASE (sevendaycyclist.com) is a surprisingly stoical alternative, albeit not rivalling the Park, or White Lightning blends discussed.
