Cranksets & Calculations











The Deore Crankset arrived and with a 32tooth front ring and 12-28 cassette, gives a range between 29.4 and 69.44 inches. A little low at the upper end for tarmac terrorism and catching riders, but plenty of torque for trailer towing and gravel stuff.  


Ideally, I’d be looking towards something in the high 70s. Will stick with it for now, unless a suitable, closer spaced option presents. 11-25 would give 33.0-74.9, which is arguably a better option. I took this opportunity to replace the chain and deep clean the drivetrain, since the existing KMC had done 1,000 plus. Besides there’s no sense in prematurely wearing cassette and new ring. I also noted that, despite the nickel finish and being fed wet lubes, it had become quite stiff and showed the ominous orange taint.   


Wintry conditions largely gone and while waiting for the new crankset, I whipped the Univega’s wheels out, given the frameset a more thorough waxing of its intimate areas and switched to the Schwalbe Billy Bonkers.

  

This also presented the ideal opportunity to give banish the congealed gloop, clinging to the cassette and Sun Race derailleur’s jockey wheels, using this Squirt Bike Cleaner Concentrate. Thankfully, the oily residue had done a good job of preserving the finish, so no call for the M16 Ride & shine M16 RIDE & SHINE | cycling-not-racing (sevendaycyclist.com) 


I’ve been getting the miles in on the fixed. Switching the Schwalbe Marathon Plus for the 42mm Continental Contact was a sensible move and I ordered replacement ceramic pads for its TRP Spyre stopper, so they’re in stock, when replacement’s next due.  


The Zefal Z11 bag is proving a very useful addition. Minimal sway (which is unusual for the bigger models, especially those tethering to the post via a single strap). The larger breed also doubles as a decent mudguard, protecting saddles and buttocks from cold, wet, slimy stuff.  


On the theme of transmissions, I’d returned from a ride, intending to simply tweak the chain tension, when I discovered some issues with the Fix-G HALO FIX G TRACK HUB | Seven Day Cyclist Tourin Tests Commuting side of the hub. Horsef*ckers! No matter, I switched back to the Aerorage wheel, until I’ve time to assess things properly.  


Oh well, might as well, give the transmission a good blitz, then feed it Squirt Low-Temperature Wax Chain Lube. Talking of the concentrate, this can be applied neat, as a degreaser, or diluted to make a bike wash.  


I’ve decanted neat into a chain cleaner receptacle, a 30/70 concentrate/water mix as a winter weight/early season bike wash. Like many concentrates, it can be applied to (a) the drivetrain via brush/chain bath, left for a few minutes, then agitated and rinsed. Or (b) poured over parts and left marinating for a few hours/overnight. This version pours easily in cold weather-noticeably so, compared with its otherwise impressive standard counterpart. SQUIRT LONG LASTING DRY CHAIN LUBE | cycling-not-racing (sevendaycyclist.com)  


Wax formulas aren’t the obvious choice for cold, wintry conditions. Indeed, I would reserve most for spring/summer. However, this low-temperature blend stoked my curiosity. Similarly, while wet lubes are the obvious default for wet/wintry conditions, they can also attract a fair bit of gunk.  


Purging this regularly (as you should) can be a tedious chore. Ignore it and there’s a very real risk of it grinding through expensive rings, cassettes, derailleur jockey wheels (and even cages). Waxy types require longer curing times but will simply scab off when leaden with contaminants. 


No need to scrub, or clean, just apply another layer and leave to cure.   

As the photos illustrate, I’ve gone this route with Ursula’s new chain, since I was there.  Also switched back to the Ravemen CLO6 Sensored Rear Light.RAVEMEN CL06 SENSORED REAR LIGHT | cycling-not-racing (sevendaycyclist.com) Fancied a formative “shakedown” blast to see how the new drivetrain components behaved and its CLO5 counterpart needed a charge.

Self Containment












 The present state of siege is presenting opportunities and threats in equal measure. Social distancing has been an ideal opportunity to get out and test kit, fettle the fleet’s specification and forward plan. I’ve been startled by the Pro Gold chain lube’s friction busting prowess.  
Even allowing for the new chain, the transmission and shifting feels that bit snappier. A notch better than the otherwise likeable Zefal Pro Dry lube https://www.sevendaycyclist.com/zefal-pro-dry-lube and marginally cleaner, thus far. Then again, its nearly twice the Zefal’s ticket price, so I’d hope so. 

Little surprise to learn the bond between my posterior and the Cycles Berthoud Soulor Saddle continues to grow. I’m still feeding the hide every few rides to accelerate perfection and there’s a definite patina forming, so all good.  

A puncture (traced to a faulty valve stem) coupled with sunnier, drier conditions prompted a switch to my fixed. The Sugru Mouldable Glue Original Formula https://www.sevendaycyclist.com/sugru-mouldable-glue-original-formu appears to have solved the Tom Tom Bandit’s wibbly bracket and I’m enjoying the Soma Condor 2 again https://www.sevendaycyclist.com/soma-condor-2-shallow-drop-bars   

Now the weather’s more spring-like, I’ve reinstated the Apeman A80 Action camera https://www.sevendaycyclist.com/apeman to the Univega’s bars. The switching of my fixed gear winter/trainer’s Titanium Torus post, back to the very likeable Genetic Syngenic Seatpost https://www.sevendaycyclist.com/genetic-syngenic-seatpost may raise a few eyebrows.  I’ve also reverted to the Spa Cycles Aire titanium saddle- it was already in situ, so why not? It’d long assumed my shape-bliss! 

However, look closely and you’ll note the Torus has a relatively pronounced layback. The Genetic is nigh on inline. The most obvious benefit of an inline model is it brings the rider in line with the bottom bracket and theoretically improves power transfer.  

It also brings me closer to the bars. The Torus’ layback also made fitting/removal of the Carradice Carradry SQR bag https://www.sevendaycyclist.com/carradice-carradry awkward, which the switch has also solved. This also presented an opportunity to put the Juice Lubes Bearing Grease through its paces. After all, if it's designed to keep bearings smooth and happy, so should last a good while on contact points.  

Ah, but then it’s also lithium-based, which can conspire with the elements, creating the chemical reaction more commonly known as a galvanic seizure. Suffice to say I will be keeping a very close eye on things. Lithium-based preps will also scoff seals and other rubberised components.   
  
When it comes to greases, we tend to test on a mid-long-term basis. This allows us to make a proper evaluation of its staying prowess, reactions to changing environments and riding contexts etc. 
Talking of contact points, here’s our clipless pedal overview https://www.sevendaycyclist.com/stepping-in-a-guide-to-going-cliple  

While social distancing is paramount, some human contact is unavoidable. Last Friday, while my helpful local garage was sorting the KA’s puncture, Maldon Shot Blasting & Powder Coating rescued the slightly scabby spare wheel holder.   

Though generally solid, upon blasting, we discovered the salt monster had been nibbling, resulting in some pitting and a small hole. Little surprise, given it was the original, thus 13 years old.  

However, we decided it wasn’t a structural weakness, so no call for plug welding. Besides, I’d come to them unannounced with a “could you blast and fit in” request.   
The thick zinc-rich epoxy primer and polyester colour coat would lock the elements, and further corrosion out. 

A big thank you to Graham, Chris and the team at Maldon Shot Blasting & Powder Coating for their kindness, can-do approach and exemplary standards. https://www.sevendaycyclist.com/aluminium-frame-refurbishment
