Calculated Gambles


 













 I’d been pondering whether the Shimano Ultegra dynohub’s grease had turned to watery gravy and needed to investigate. I’d always understood Shimano, unlike Shutter Precision, were partially user serviceable. The right side could be stripped and overhauled using a 15mm cone spanner and 17mm for the locknut. Trepidation cast aside, I rounded up spanners, greases, clean rags and solvent. The locknut was quite stubborn, which in some respects is a good sign, but submitted without recourse to penetrant spray.

 Locknut and cone removed, the grease had assumed an oily, but still functional state. The loose balls and bearing races were also free of pitting and similar wear. I toyed with the idea of repacking with Juice Lubes Slick Juice but reached for their Bearing Juice The Juice Lubes Bearing Juice Long Term | cycling-not-racing on the grounds of outright staying prowess. Even allowing for the recent heatwave, viscosity meant it was a little messier to apply but no issues once I’d transferred the excess to the cone.

This would also help seal the elements out. Getting the bearing tension bang on took four attempts. Back in the forks, neurotic checking revealed zero play. Hub strips tend to be annual, or thereabouts, so I can get away with some cheap but cheerful cone spanners. Unlike some cheapies, Lifeline seem accurately machined and sturdy enough for periodic use.

I’ve since invested in this 15mm Park, replacing the Tacx someone borrowed and felt entitled to keep.  I took the Slick Juice route with the trailer’s hub, which, as expected has reduced friction. Will be interesting to see how well it stands up to the elements, especially since it's right in the firing line of puddles and other dodgy water.  I’ve periodically had the idea of upgrading the trailer’s wheel but talked myself out of it. A New Old Stock Deore unit was waved under my nose for less than £8, so I indulged. I’ll seek out a suitable rim, but only at the right price, since all this is want, not need.  

Overhaul complete, I treated Denise to a deep clean. Though not obviously dirty, given the prolonged, dry spell, rear wheel, rack, rear triangle and fork crowns were coated in a stubborn dusty layer. Buckets, Muc-Off Chain Wax Cleaner Muc-Off Chain Wax Cleaner 500ml | cycling-not-racing, Juice Lubes Bike Cleaner, Muc-Off MO94 Muc-Off MO94 Multi Use Spray | cycling-not-racing and assorted brushes rounded up, twenty minutes later, Denise was washed, dried and lightly re-lubed. Knowing when to down tools and pack up-quitting while ahead is another important skill. Sometimes, if it aint broke, don’t fix it.  

 The chain was still below .25 on the chain wear indicator, and I was going to run the fleet on wax lubes for as long as conditions permitted. Back to testing Ursula’s M Part Ridge Pannier rack and some fixed gear frolicking aboard Muffin. Having discovered the Ride’s top section broader than the Summit-confirmed when strapping my long serving Carradice Super C atop.

This was filthy, so I decided to take it for a thirty-degree Tour De Zanussi, adding some wash-in proofing. Now, this isn’t strictly the way to treat cotton duck, so a gamble at my own risk. However, it seems to have emerged in good health. I decided to take my 25-year-old SQR Tour the same route since, while very solid, it was looking very jaded. The sun and other elements had bleached the fabric in places and there’s no getting that back, but it was at least, clean and re-proofed.   

This also presented the ideal opportunity to give the washing machine’s soap try a thorough cleaning to remove accumulated soap scum and similar.

 Ideally, we should follow manufacturer instructions regarding care to the letter and have no recourse, should we deviate. Those of you looking to reproof cotton duck luggage should give them a good wash and then apply Carradice’s own reproofing wax.  I even found a box of high-quality patches, which was another pleasant surprise.

One thing led to another. I decided it was high time I had a sort through of the work bench. I decanted a myriad of small fasteners, mounts and similar into dedicated zip lock baggies and found and appropriate storage box. I’d been slightly disappointed by the OEM Coospo CS600 Coospo CS600 GPS | cycling-not-racing Garmin pattern mount adorning Ursula’s bars but hadn’t found a suitable contender.

Firmly in the zone, I discovered a couple of Magicshine mounts- the type employed on the marque’s Allty and Ray series. These employ a Garmin pattern head mount and a series of straps, so a universal fit. One, already attached was in Goldilocks territory. Sixty seconds later, a neater, sturdier host. A small but very satisfying upgrade.

Next, I decided to road test my hypothesis that wrapping some scrap inner tube around the quick-release trailer hitches would act as a damper. One producing a tighter union, silencing a slight rattle.  Formative impressions are favourable, although trailer release is less convenient than ideal. Maybe thinner tube, or even electrical tape is the solution...
