Drivetrain Dramas & Rubbery Delights












 One thing led to another-we know how those sessions go. A chance inspection of Ursula’s chain revealed not one, but several crumbling links, which would explain some jumping at certain points along the cassette. Not the time I’d expected to replace it, but I decided this was the safest option, relegating the existing part-worn KMC to salvage/spares duties-into the SQR tour (via a resealable bag), it went.  

Now a skipping chain can be down to several things. Could be a stiff/damaged link, a worn cassette/sprocket, a kinked, or similarly worn cable, or a bent derailleur/hanger. I had recently replaced the inner and outer wire, we hadn’t been in a spill, so not a hanger issue.    

The Velo Orange Rubbery Bar tape is certainly making a positive impression.   

 

Reminiscent of the Lizard Skins DSP in terms of texture, it’s 3.5mm thick, yet weighs 147g (including plugs) and is markedly easier than most to wrap. I was seriously impressed by the Control Tech’s overall performance, but it wasn’t very malleable, thus required patience and very firm pressure to fit. No such problems with the Velo Orange and even the rubbery finishing strips were decent quality.   


Length is suitably generous too, a good six feet, so I had plenty left after dressing the Soma Condor 2. I was almost tempted to dress the right-hand chain stay, to protect it against accidental chain slap. However, this was a solution looking for a problem. I figured it would come in handy later down the line, so it went to the appropriate spares box.  I also decided to mix things up by switching from the K-Lite Bike Packer UltraK LITE BIKEPACKER ULTRA DYNAMO LIGHT | cycling-not-racing (sevendaycyclist.com), to the K-Lite Bike Packer Pro V2 K LITE BIKEPACKER PRO V2 FRONT LIGHT | cycling-not-racing (sevendaycyclist.com) 

I am pleased, dare I say relieved that the new seat collar and binder bolt appear to have cured the fixed gear winter/trainer’s post slippage issue. 


Glad I bought another spare collar and hanger, since the price was keen, and these small parts always fail at the least opportune moment. The System EX Security SkewersSYSTEM EX SECURITY SKEWERS | cycling-not-racing (sevendaycyclist.com) have also been a useful addition. Sure, they’re not going to offer any real defence against a tea leaf wielding a 5mm Allen key, but they hold a disc wheel very securely, prevent opportunist theft and practical jokers.  


Cleats are another small but significant part that lead tough lives and only court attention when their hardware seizes, or they don’t engage/release reliably. I discovered two spare Shimano sets in the small parts drawer, while I was rooting around for post hardware. Existing cleats are OK, but I may pension off come October, as precautionary, seasonal maintenance.    


I also unearthed this Tern Vizy light, while rooting contemplating switching Ursula’s K-Lite Bike Packe Ultra for the Bike Packer Pro V2 K LITE BIKEPACKER PRO V2 FRONT LIGHT | cycling-not-racing (sevendaycyclist.com) since I was in the mood for mixing things up a bit and maximising handlebar real-estate. The Vizy is an interesting concept light. It pumps out a maximum of 60 lumens and combines a rear light with a big red arc around the bike and rider.  


It lacks the outright presence of Magicshine See Me 200, (presently adorning my fixed gear winter/trainer’s right-hand seat stay) but still has some charm. I’ve chosen to post, rather than wishbone mount, since this seems to project the light’s arc most effectively, so for now, it stays.   

Peaty’s Link Lube wet continues to impress me with its staying prowess. I’m easily 500 miles in and there’s no call to top up the fixed’s KMC chain. Contaminant is moderate, although less than typical of wet types-wiping the side plates every week hasn’t been necessary to date, although the depths of November may say different.  I remain impressed with the Peaty's Speed Grease, too PEATY'S SPEED GREASE | cycling-not-racing (sevendaycyclist.com) 


I was also searching for a VDO sensor, so I could pair the second M3.1 head unit and run it on Ursula. This proved truly elusive. However, a few days later, some Sigma goodies arrived for testing.   


The BC9.16 wireless computer is aimed at those riders seeking to improve fitness but without online connectivity. It has 11 functions- current speed, average speed, comparison of current/average speed, maximum speed, distance, total distance, ride time, total ride time, clock, calories and total calories burned. All I will need, save perhaps for a backlight.  I was suddenly struck by just how similar the mount and sensor were compared with the VDO M3, so I tried pairing the VDO head unit and sensor, without success but satisfied my curiosity. 

 

Then we have the German marques Blaze and Infinity Rear Lights. The Blaze promises visibility up to 500metres, daytime running modes and a “braking function”. The Infinity, promises 16hour run time, StVZO approval and claimed visibility to 500metres.  

Autumn is creeping ever closer.  With it, another sequence of shortages. The hospitality industry is not only struggling to find suitably qualified staff but supplies of beer and CO2 gas are also in increasingly short supply. This also bodes badly for welders/metal fabricators, since CO2 is a commonly used in shielding gas. Argon/CO2 being a blend I am particularly fond of.

Hollow Thoughts










 250 miles in, I’m arriving at the conclusion my shim experiment wasn’t the success I’d initially thought. However, I’m glad I went this experimental route. It didn’t cost me anything, since I already had the components and wanted to see how much difference a Hollowtech system would make to my Univega’s drivetrain.  

My fixed gear winter/trainer ran a Truvativ external cup system for a while and I’ve tested machines with external cup groupsets. There’s a big difference between living with a system for a few hundred miles and a machine that you ride year-round and have exceeded 100,000 on. 


Anyhow, I’ve decided to stick with Hollowtech and acquired a Deore unit, which aside from being the right fit, and will save some weight. Afterall, Zee is designed for downhill duties, so overbuilt for a mixed terrain, rough stuff tourer cum daily driver. 

 

Replacement crankset in question comes with 32 tooth, 96BCD ring, which gives rise to reviewing gearing. Might need to switch the cassette to something more closely spaced to compensate and avoid warp speed spin-out on the road/unevenly wearing certain sprockets.    


For the time being, I’m getting the miles in on the fixed, which is no hardship, especially since I dialed in the chain line. The Acros Silicone Wrap Handlebar Tape LONG-TERM TEST: ACROS SILICONE BAR WRAP | cycling-not-racing (sevendaycyclist.com)    

Is still going very strong but looking a little grubby, so the arrival of this T-One Mr Fantastic Handlebar Tape, sent to me by Greyville Enterprises Greyville.com - T-ONE Mr Fantastic Handlebar Tape: Orange is also 100% silicone and promises to be extremely durable. 


For example, UV resistance is reckoned between –40 and +260 degrees. Uncut, it carries a 24g weight penalty over the Acros and over double that of Genetic Flare Silicone Bar Wrap GENETIC FLARE SILICONE BAR TAPE (sevendaycyclist.com) 


Being a naturally grippy fabric, silicone tapes require no adhesive backing, so bar swaps, cable changes etc don’t spell the tape’s end and make the other tasks that little bit quicker/easier. Talking of which, it’s quite relaxing to fit, requiring nominal pressure-closer to the Genetic Flare, in this respect.    


Oh, and lighter colours, such as fluros keep their looks longer since you can pop it on the washing machine at 30 degrees. Talking of which, it will be interesting to see whether the smooth texture means it stays cleaner/is easier to clean, compared with the Acros’s embossed finish.  


Formative impressions are favourable- the aesthetic is less chunky than the Acros but still does a capable job of damping low level vibration. I’d also toyed with porting the K-Lite Bike Packer Ultra over to the Genetic Neuron Accessory Bar GENETIC NEURON ACCESSORY BAR | cycling-not-racing (sevendaycyclist.com) but ultimately thought better of it. 


More pressing was a sudden loss of braking-pads again. Thankfully, I had replacements in stock but it’s amazing how quickly these get consumed in bad weather. This also presented an opportune moment to switch from the Schwalbe Winter Plus to this Continental Contact plus TESTED: CONTINENTAL CONTACT PLUS TYRES (sevendaycyclist.com)  


Back to the drivetrains...Well, I’ve reached my conclusions regarding the Muc-Off e-Bike Wet Weather Ceramic Chain lube MUC-OFF E-BIKE WET WEATHER CERAMIC LUBE | cycling-not-racing (sevendaycyclist.com) and Weldtite Ceramic Chain Lube is also making a generally positive impression. In terms of consistency and friction, it’s quite close in characteristics and staying prowess to Juice Lubes Ceramic Chain Juice JUICE LUBES CERAMIC JUICE | cycling-not-racing (sevendaycyclist.com) 


I’ve noticed a tendency for it to migrate away from the rollers in very wet conditions, although residual stuff seems to get reclaimed from the cassette. In fairness, The Juice and Weldtite Ceramics are designed for fair, rather than foul weather but it’s interesting to see how they behave in wetter conditions.  


Given the forecast these coming weeks, I may be reaching for the Muc-Off –50 MUC-OFF -50C CHAIN LUBE | cycling-not-racing (sevendaycyclist.com)  again. For the time being, I’m enjoying the lower friction, which is particularly apparent, riding fixed. Steve’s also been impressed by this Rohloff blend ROHLOFF SPECIAL BIKE CHAIN LUBRICANT | cycling-not-racing (sevendaycyclist.com)
