Ahead of the Curve













While sweeping through the backroads, Ursula and I spotted this stricken Skoda. I’ve seen two other vehicles- a BMW Mini and a Toyota Rav4 meet the same fate over the past three years. Whether this was a blend of too much speed, poor tyre condition, mud on the road, and/or a deer leaping out is impossible to tell. However, having checked for anyone trapped and unconscious, I hopped back aboard Ursula and continued riding.  

The sugar beet crops are being harvested, so tractors and other large agricultural vehicles have been coating the tarmac with greasy, muddy stuff. Fabulous for assessing the Schwalbe Smart Sam’s handling prowess in muddy contexts. I was pleasantly surprised by how well they’ve behaved in these contexts and equally impressed by their mud-shedding ability once back on metaled roads.  


I’m someone who replaces consumables as a matter of course but there are some basic pre-seasonal checks that we should all perform. Especially on a working/winter bike. In my book tyres, wheels, chains, braking-cables/hoses, and pads, and contact points.  

Start by giving the bike a good wash and hard paste waxing-this makes potential issues easier to spot and nicer to tackle-especially if you're farming a job, say a brake bleed to your friendly mechanic.  


Now inspect the tyre casings for wear, bulges and similarly structural stuff. Small nicks and cuts in the tread can be filled with super glue but pension off, if they’ve clearly done a high mileage, or more serious wear’s evident 


A sudden rush of punctures is another sign an otherwise rugged tyre is coming to the end of its reliable life. I’ve experienced this with some iconic models, including the legendary Schwalbe Marathon Plus.  


Will be interesting to see if this fate strikes the Maxxis Refuse MAXXIS REFUSE TR FOLDING TYRE | cycling-not-racing (sevendaycyclist.com) as the darker months and less forgiving conditions unfold. I may well switch the fixed gear winter/trainer’s rear for the CST Xpedium Level 6 700x35C Single Compound 60tpi Wire Bead Tyres CST Xpedium Tyres | cycling-not-racing (sevendaycyclist.com). Single compound tyres tend to give a more direct ride but last longer, which is another consideration during the winter months  


In terms of wheels, check rims for wear, dings or similar imperfections and replace before they wear through. Give the wheels a spin and check for any side to side, or up n’ down play. Are all the spokes uniformly tensioned and all present Check the hubs for any grittiness, grumbling or side-to-side play.   


Cup and cone types should be stripped, bearings replaced and re-packed with a stoical grease at least yearly, more regularly on bikes that serve in harsh contexts. Same goes for headsets, especially on bikes shunning mudguards. Metal contact points, such as seat posts and stems should also be re-greased to prevent seizure-related issues. While you’re there, it's worth checking bars and posts for any signs of hairline fracture- especially around the stem face bolts. Check grips, or handlebar tape condition and replace as needed.  


I’ve tended to do this come autumn to coincide with cable replacements, I also find fresh bar tape one of those small but significant motivators, encouraging me to get out and ride. Presently the Souma Leather Handlebar tape is faring very well on Ursula and fixed gear winter/trainer Souma Leather Handlebar Tape | cycling-not-racing (sevendaycyclist.com) and seems tolerant of being re-wound following cable replacements, so stays.   


Saddles, especially the traditional leather type appreciate periodic licks of leather proofing to keep them supple and generally protected from the elements. Leather-covered models should be checked for signs of wear-a bit of electrical tape around the rear will protect against damage when leaning the bike against walls etc. Check the rails too, dents or similar damage signals replacement-failure is often unexpected and potentially very painful.  


Cables are things I replace as and when but those with more prescriptive service intervals should consider replacement every season. Sealed systems can be stubborn to fit and the outers are a little hostile to painted or lacquered hosts, so a strip of helicopter tape where the two meet is a good bet.  


However, they tend to be fit and forget. I prefer systems with compression-less housing since these have minimal friction, which really comes into its own with cable-operated disc setups. Pads also need a careful eye. In terms of discs, I’ll replace them when pads are down to 1.6mm and during winter, opt for either semi-metallic or fully sintered models for added bite.  


I’ve been particularly impressed by Disco Brakes Semi-Metallic pads Disco Disc Brake Pads and Wavey Rotors | cycling-not-racing (sevendaycyclist.com). Calliper and Cantilever pads usually have a wear indicator, so keep an eye on those and replace as needed. Upgrading the pads can bring budget stoppers up a couple of notches too. Otherwise, inspect for grit and other stuff regularly to prevent it from consuming pads and rims. 

 

Chains. Yep, these can wear at an alarming rate, especially during winter when you’ve got wet, gritty roads and wet lubes involved. Invest in a chain checker (Basic but serviceable models are only a few quid). Rule of thumb, replace 11-speed derailleur chains when they hit .5 on the tool, 7-10 speed around .75 and single speed 3/32 models at 1.0. Chains are comparatively inexpensive compared with other drivetrain components, so regular replacement will save a lot of money, longer term.

Shot Bolt, Sinking Feelings & Reprieves


 







I go through phases of tweaking saddle height but before any of you have visions of me constantly fettling mid-ride, a ’la Mr Rottler (who was so renowned by his teammates for perpetually adjusting his, they named a spanner after him), mine usually coincides with a change of seat post, saddle etc.  


Getting those precious late summer miles in on the Holdsworth, I was conscious of my saddle being a little low, suspiciously so.  


Having concluded the ride, inspection revealed the Crank Brothers post was indeed creeping very slowly into the frame. I traced this to a fatigued seat bolt- an easy fix. Replace and snug down to the correct tolerances. Seat collars, at least, the modern types are around the 6nm mark (but do check, they can be lower). Sensible, given the popularity of carbon fibre posts.  


However, it would seem more traditional binder bolts and metal posts are 9-12nms. This lower default may also explain the steady downward creep. Either way, I replaced the electroplated Cro-moly binder bolt for another, added a lick of Peaty’s Bicycle Assembly Grease PEATY'S BICYCLE ASSEMBLY GREASE | cycling-not-racing (sevendaycyclist.com) and snugged that down to 10nms. Tweaked the headset bearings by a fraction of a turn, since opportunity presented. Two little jobs off the list.   


With this and roads carpeted in dung and agricultural mud, I’ve switched to racking up the miles aboard Ursula and those Schwalbe Smart Sam tyres. Farm tracks, unmade roads and bridlepath have been our 5am playgrounds. While primarily designed for dry, hardpack conditions, they’re proving less ponderous than might be expected, suggesting the raised centre strip does offer some tangible benefits on metalled roads. 560g apiece also helps in that respect.  


Schwalbe suggests they’re suitable for touring. In the broad strokes, mixed terrain sense, with the emphasis upon trails, I’d agree but models like Specialized Crossroads Armadillo and indeed, Maxxis Overdrive Excel Maxxis Overdrive Excel Tyre | cycling-not-racing (sevendaycyclist.com) are better choices for longer spells on the road and gentler off-piste meandering 


I wasn’t surprised by the amount of dust clinging to the Smart Sam and Ursula’s frameset given the extended hot, dry spell, although, the falling leaves now serve as a reminder autumn is fast advancing. I’m sticking with waxy-type chain lubes for the moment, since they’re much cleaner and will flake off, taking contaminant with it.  


However, I noticed a very clean chain and faint metal-on-metal tinkling sooner than expected, so strongly suspect I’ll be switching to a middleweight blend next time. Weldtite TF2 Performance All Weather TF2 PERFORMANCE ALL WEATHER LUBRICANT | cycling-not-racing (sevendaycyclist.com)  is something of a default for me but (and while it may seem an odd choice, given the season, Muc Off-50 Chain lube MUC-OFF -50C CHAIN LUBE | cycling-not-racing (sevendaycyclist.com) makes a surprisingly good everyday blend-it's a little lighter than the Weldtite TF2 Performance All Weather, and doesn’t contain PTFE.

  

Talking of unusual choices, I’ve discovered carbon gripper paste has also proved highly effective at securing electric toothbrush heads...For context, I bought some replacement, genuine heads for mine and they’re what might be best described as a “pattern” fit. A sudden flash of inspiration saw me reaching for this Weldtite Gripper Paste and this gut feeling paid off.    

Elsewhere, there’s been plenty of mist, and I’ve been pleasantly surprised by how well the Infini Sword Infini Sword Super Bright Light Set | cycling-not-racing (sevendaycyclist.com) have performed in these contexts, the rear as my sole light.


The flashing modes are ultra frugal-Infini reckons 200 hours and I’ve come within a few minutes of this.  Brilliant for marathon night riding and as a dynamo companion. Peripheral prowess is better than a slimline profile would suggest, although when conditions have been in pea-soup territory, I’ve felt that bit safer with the Ravemen TR200.  


As the name suggests it delivers a maximum of 200 lumens and has a sensored 100-lumen “braking” function, which really brings the 40 and 20-lumen steady modes to life along the backroads. Alternatively, in the back of beyond, disengage the “braking” function, select one of two 100 lumen flashing settings and save some juice.
