The Chain Again


 
As I predicted, two weeks hence, the chain tool tolled judgement day for my Univega’s chain. The blend of flooded, silty roads, wet lube and long, steady miles had done the deed. I was rather hoping this would coincide with the arrival of a 38 tooth CNC machined ring, but hey-ho.  

No sense shortening cassette, derailleur and ring-life. Since I’m running a 1X setup, ring wear is less of an issue compared of a double, or triple. A few minutes rummaging in my freshly reconfigured transmission spares bin and I emerged triumphant, with a nice shiny KMC.  

I know a lot of folks like the “magic links” and they can be super-convenient. I just prefer the security of a traditional pin, so pruned and joined accordingly. This served to highlight a very palpable, matted layer of wet lube and accumulated contaminant engulfing the cassette.  
Out came the Juice Lubes Dirt Juice Chain Cleaner https://www.sevendaycyclist.com/juice-lubes-dirt-juice-chain-cleane

Transmission stripped bare; I’ve decided in favour of a more basic middleweight ISO/PTFE lube. Less stoical than a wet lube but much cleaner, and March is looking less challenging weather-wise.  In any case, I will be switching to this Pro Gold Pro Link Chain Lube, which should be a good fit, season-wise. 

According to their blurb its  
A thin-bodied lubricant which utilizes metal friction reducer technology for smooth shifting and a quiet drive train. Does not build up or become tacky; sheds dirt, mud, and abrasives. Also repels moisture and prevents corrosion”. Will be interesting to see how it performs in the real world. 

Surprising just how much difference a new chain can make to the transmission. On many levels this is obvious, but the existing chain had only just reached pensionable, rather than being completely shot. Shifts were immediately snappier and more reliable. More remarkable was just how quickly weather and contaminant euthanised it.    

I’m still looking around for a 38 tooth 94BCD ring, which will afford a more seamless choice of gears. For years, Chris Bell produced precision-engineered bespoke elliptical and round rings but sadly, succumbed to prostate cancer in 2016. 

By the same token, while I’m keen to keep solid components going, a new, external bearing crankset, might prove the most cost-effective solution. Assuming of course, I can’t acquire a 5-arm Stronglight/similar at a favourable price.  

The other option is to plump for a smaller ring and road-biased cassette. I’ve run this configuration in the past. However, unless the former was seriously cheap, it would also mean replacing the cassette.  


A moot point, if both were edging close to retirement, but they’re not. While I love a well-stocked spares bin and the economics/horizons this presents, I don’t want to be hoarding heaps of stuff that are too much of a compromise (and thus won’t get used, let alone worn out).  

Rounding up the drivetrain theme, this Topeak All Speeds Chain Tool also arrived for testing. Aside from the industrial good looks, it includes a chain hook to hold the chain together while you drive the pin home.  
I was also pleased to note there’s a spare drive pin that’s threaded into the base. Not only does the design promise to tackle chains from single, through to 12 speeds, this includes Campagnolo 11speed hollow types.
  
This purging also prompted me to polish and wax the frameset.  
Grit can slip behind cables, leading to paint-chew. Protective cable rubbers and clear stickers/ “helicopter” tape are the simplest, most effective preventions. In my experience, thicker ready-cut frame protection patches are quite durable.  

Eventually, PTFE rich maintenance (and other solvent-based aerosol products, for that matter) will dissolve their adhesives-especially those around the head, seat tube and chainstays, inducing lift and peel. This time round, I plumped for a supermarket wax, primarily because it was within easy reach. Bargain basement but easy to apply, and supposedly suitable for all surfaces.   

Staying with cleaning a moment, Steve and I have been very impressed with Rock N’ Roll Miracle Red Concentrate Multi-Purpose Bike Cleaner https://www.sevendaycyclist.com/rock-n-roll-miracle-red 
An incredible versatile that will clean everything from scuzzy steeds and grimy hands, to carpets and clothing.  Those who want to add a little electrical assistance to their commute, or utility ride might be interested in our review of this Raleigh Stow E Way Folding E Bike   https://www.sevendaycyclist.com/raleigh-stow-e-way-folding-e-bike

Hub Deep













It’s not what but who you know…Word of mouth has seen Seven Day Cyclist invited to attend the upcoming Adventure travel film festival www.adventuretravelfilmfestival.com/uk-festival , which is a great opportunity to get inspired.

Traditionally this attracted 4 wheel drive and motorcycle explorers but we’re told cycling audiences are also beginning to gravitate; hence our attendance. On subject of touring/exploration, Steve Dyster has found plenty of decaying soviet era relics; especially in Germany’s easterly towns and villages.

At this point, I felt an acute sense of excitement and before he moved back to the west, begged him for some photographic evidence of this delightful derelict industrial porn...Hopefully I’ll be able to share this very soon-he’s due back in the next few days.

Several hundred miles in and the Ilpompino’s FSA headset bearings remain well behaved, although its replacement arrived and will be substituted at a convenient moment should the dreaded slop rear its ugly head again.

Talking of which, I returned from a weekend’s social photography in Bedford and decided summer’s decidedly soggy official start should coincide with the introduction of WD40 dry chain lube.

For the past few weeks’ I’ve fed the fixers Green Oil’s chain wax, which is a super clean brew with friction in snake’s testicle territory. While the formulas are very different, one derived from plant based ethanol and similarly natural (though extremely flammable!) components; the other employing old school PTFE.

Both are very runny; so deploy in well-ventilated areas- away from chain smoking neighbours or other sources of ignition and keep some old rag/kitchen towel hovering beneath to capture the inevitable overspill.

Green oil likes a double up and while directions suggest it’ll cure in around six minutes, twenty seems optimum, even on very warm, arid days. Technically; as is the case with many PTFE fortified blends, WD40’s follows the drizzle on, dismiss excess and scoot-off narrative.

In practice, leaving it twenty minutes or so, improves staying prowess, especially in slightly changeable conditions. This, coupled with the fact that its 100ml bottle slips nicely into most jersey pockets/saddlebags means it’s convenient for roadside top-ups too

First impressions along waterlogged lanes suggest they’re on the right lines when it comes to staying prowess. I’ve avoided roads which have become virtually impassable rivers; claiming late model SUVs, vans and smaller vehicles. 

Nonetheless, some sections were deep enough to engulf said fixer’s stainless steel chain and lap at its sealed hubs. We’re only seventy miles in so far, which in many respects is nothing, although I’ve often found myself topping up those lightweight ISO/PTFE formulas around this point into a similarly wet spell. The next three hundred miles could prove very interesting, or highly predictable... 

Elsewhere; I’ve been busy in the midlands; succumbing to a very nasty bout of food poisoning; demanding a couple of stops at Northampton and Toddington motorway services. In any case, the M1 was pedestrian due to a series of equally visceral collisions, one involving a Truck and several cars.

My series of Children’s stories, characters and themes continue to develop. Once we’ve agreed the second draft of our prequel’s narrative, Michael J Murphy will commence the initial sketches for approval, before bringing them to life digitally.

The Free parable T2 trailer continues to impress me. Its long sleek profile is reminiscent of a spine and when combined with its waterproof dry sack, will manage a competitive 30kilos plus of kit without feeling overburdened.

Being 6061 aluminium, it’s a little lighter than the Yak patterns, though the same rules apply-plan your gear changes carefully, before reaching junctions or climbs and, in my case, over- estimate your turning circle. That said; it tracks more accurately behind and coupled with a slender profile, makes negotiating tighter gaps-traffic, alleyways or indeed, forest trails.

The “spinal” design and plastic mudguard also means annoying chatter is a moot point when gliding over inclement/washboard tarmac. OEM wheels tend to be another afterthought. While hardly exotic, the T2’s 12 inch rolls surprisingly efficiently and while there’s an argument in favour of being able to strip and service/rebuild a basic cup and cone hub in the back of beyond.

In practice the sealed “fit n’ forget” units turn very smoothly and shouldn’t require any intervention in the longer term.  There are a few minor limitations with the design, mind. Those, myself included; who are less orderly in their loading, may find models with broader platforms more convenient for everyday bung in and go missions.
