Striptease










A colder, though dry streak has seen me pluck the Holdsworth from hibernation for some fun along the backroads. The arrival of this Stem Captain clock, also proved an ideal opportunity to strip and re-grease the Woodman Saturn headset’s lower race and needle roller bearings.
The Stem captain is a range of mounts, from clocks and old school compasses to Garmin GPS.
These turn the “dead space” into something more useful. It’s a concept that has grown on me, not to the point where I’d consider it a must-have across the fleet but being able to glance down, rather than grapple with a sleeve, or scroll through a bar mounted computer.
Working on the basis, you’re running the classic star fangled nut configuration and your Aheadset is properly pre-loaded…It’s literally a question of whipping out the 5mm Allen screw and replacing the top cap with the Stem captain and snugging it down as usual.
Next, seat the clock into place with the clear silicone grommet. This holds it snug.  
Things aren’t radically different when it comes to expandable wedge types, common to the Woodman and obviously, carbon steerers.
However, performing said swap at 10am on a cold Saturday morning, on “The soviet -block” (a section of 70’s concrete designated for bike washing and messy fettling) I managed to get the lowest, threaded assembly lodged in the fork’s alloy steerer. 
I attribute this lamentable scenario to the shock of hearing my neighbour, offering their heating engineer de-caffeinated “coffee”.
Think silent scream of revulsion. Said scenario was all the more surreal on account of him hollering from the chimney stack and I “dressed” In Marvel superhero lounge pants and duvet type, hooded cardigan.
Fork and threaded section retrieved, using a scrap mudguard stay (a spare spoke might’ve been a few seconds quicker), I reassembled the bung in its correct order and retouched the forks’ alloy ends with some quick drying gloss black hobby enamel.
Ideally, any retouching should coincide with a few days curing but since the brand in question dries quickly, I risked it for the proverbial biscuit. I’ll build it up in thin coats while it’s tucked away for winter.
Finish line ceramic applied to the lower race, I reinstated the front end, refitting the front brake and double checking the Aheadset was free of unwanted play. Some fresh finishing strips-colour coordinated electrical tape, completed the tune-up and satisfied with the hour’s efforts I headed indoors for sustenance.
Frames are pretty durable. Said frame has been repaired-new bottom bracket shell, minor pitting and small dents addressed. Even carbon composites can be fully rebuilt following some jaw-droppingly serious crashes https://www.sevendaycyclist.com/a-visit-to-carbon-fibre-bike-repair .
This steel frame intrigued me for several reasons. I was initially struck by the smooth fillet brazing and something told me it was one of those frames that had been passed through several club riders. Looking closer, I was surprised to discover fractured “ear” around the seat collar, yet extensive and recent brazing is very apparent at the Bottom bracket shell, down tube bottle bosses and mech hanger.
From the photo, Lee Cooper www http://leecoopercycles.webs.com/ reckoned the work was repairable and around the £30 mark, although worth blasting first to assess the frame’s overall structural integrity.
Elsewhere, those Rock N’ Roll goodies have again, been intercepted. No fault of the supplier, rather seasonal pilfering, within the postal system which, sadly, isn’t that uncommon this close to Christmas.
Most communications workers and delivery drivers are honest people, who work incredibly hard. This also applies to seasonal operatives-I’ve been one, so know. 
Unfortunately, during periods of high demand, there will always be a small, feckless minority, who will steal, or just take them back to the sorting office/depot, because they cannot be arsed to complete their round. 
Right, ending on a positive note. I’m off to sort some reflectors and other lighting ready for next week’s model shoot down in sunny Sussex.
