Lock-rings are Like Busses....







I’d been waiting ten days for one, then, in alignment with Murphy’s law, two arrived-a day apart. Some of you will be thinking hmm, couldn’t you just use a cassette lock-ring, after all they tighten using the same tool? Yup; got curious and took that route, with one from a 12tooth cassette but can confirm incompatibility.

No matter, a lick of Park PL1 grease, nipped 40nms tight, wheels were swapped, and testing of the Halo/ShutterPrecision SL9 commenced.

Size was the SV9’s initial draw. I was curious to see how it compared to the SV8. https://www.sevendaycyclist.com/halo-rim-and-shutter-dynohub-disc-b  Some Audax and winter roadies were impressed with the SV8’s output. Several commented they would want something sleeker than this and other, more traditional dynohubs.

According to the Shutter Precision blurb, the SL9 is an improvement on its predecessors, achieving similar output and lower resistance in a more compact package.

A moot point with smaller wheels, its been suggested there may be some loss of output on 700c builds, depending on other factors, such as lamp output/quality. I’m yet to notice any drop thus far but we’ll see what presents in the next 400 miles or so. 

In other respects, the wheel arrived true and very well tensioned, with no hint of pinging, or similarly disconcerting sounds, associated with bedding-in.

Stark contrast to the Teenage Dream’s Mavic Ma2/Campagnolo Athena wheelset, bought mail order, back in 1991. Right from the first few pedal strokes, those stainless spokes were pinging n’ popping for the first five miles. I let them bed in for a week, or so, then headed to my local wheel builder, for a quick tune up.

Admittedly, said machine doesn’t do massive mileages, at least compared with my Univega and working fixed. However, 27 years hence, they’re still serving me well enough, so can’t’ve been too badly built!

Back to the SP, I will alternate between the Trelock https://www.sevendaycyclist.com/trelock-ls960i-dynamo-front-light  and Exposure Revo (MK1) lamps, see how the hub behaves over the coming month, 400 miles. With autumn’s silent, incremental creep, I’m working through summer kit, treating the KA’s chassis and underside with home brewed Waxoyl and contemplating the winter riding wardrobe.

The working bikes chains are presently dressed in this Weldtite TF2 advanced ceramic chain wax. Now, there will be some of you, who will say wax lubes can be made for literally pennies, at home using a mix of candle wax, Xylene and other solvents. True and I’ve been very impressed by this backyard alchemy.

However, these are very volatile and could very well result in a major, life changing explosion. DISCLAIMER: ANY BACKYARD ALCHEMY IS PERFORMED ENTIRELY AT YOUR OWN RISK.

If price is your sole motivator, buy five litres of basic 15w/40 motor oil and apply half a capful to your chain(s) wipe away the excess fastidiously and clean contaminant from the side plates, on a weekly basis. Cleanliness, low maintenance and indeed, low friction are the main draws of wax lubes.

With the traditional/emulsion types, contaminant became embedded and then flaked away, leaving a thin layer of lubricant behind. Fine in dry, dusty conditions, they were easily dismissed come the first hint of a shower.  

More recent, sophisticated formulas tend to run cleaner in the first instance and are becoming increasingly durable. So far, I’ve done 250miles on the first helping, in changeable, although primarily dry conditions.

I am expecting it to cruise past the 400mile marker, without relenting. Cleanliness, is closer to Smoove Universal Chain Lube https://www.sevendaycyclist.com/smoove-universal-chain-lube-summer-  https://www.sevendaycyclist.com/tf2    rather than its TF2 counterpart. There is some modest contaminant and a 10hour curing period won’t suit everyone, but on the plus side, it seems more resilient.  

I’m naturally intrigued as to its longevity during precipitation and general seasonal dampness. Given forecasters are promising an Indian Summer, it may well be in evidence several weeks down the line.
