Cheers. Might end up doing that if the machined seat post slips in the frame!

Have been riding a rim with similar cracks on my Giant summer bike for the summer. Just marked the ends of the cracks and monitored them for growth. The cracking occurred after I tweaked the wheel and slightly increased the tensions, so obviously some rims are not very tolerant of increased spoke te...

At 47 I find the compact double gearing too high. Usually I have a top gear of around 100" and aim to use my large chainring for normal riding and the smaller 'rings for the hills. I've resorted to fitting the Spa Cycles triple chainsets to most of my bikes. Only problem is I found they don't r...

Bike isn't built up yet. Had to leave frame/forks in York to get the seatpost machined to fit.

When it's built I'll try both seat posts. However, from past experience it's been an issue for me of seatposts slipping even when they're not as loose as the seatpost Spa sold me.

Result was the seatpost the shop uses was still loose enough to rock in the seat tube, although around 0.1mm larger in diameter than the original 'post I bought to build the bike. So, I left the frame with my mate and supplied two 27.4mm seatposts, which would not fit in the frame, which he had a fr...

Will be collecting the frameset from my friend in Yorkshire this weekend, after he had a friend of his machine down a 27.4mm seatpost to hopefully fit the frame. However, I'd be interested to know if there are any external clamps out there which could be fitted to a 27.2-ish seatpost to stop the sea...

Another shout for Silkolene Pro RG2. Been using it for years and seems to last well enough in wet conditions. It's formulated for motorcycle bearings, perhaps a bit thicker than ideal for bike bearings (NLGI 2) but it becomes more fluid with use and I put it in my freehub bodies rather than oil. As ...

For some reason (which I can't find!) 531 appears to be averse to the higher temperatures generated by TIG welding, but brazing has been used to build 531 frames for generations, However, it seems the tubing is now available to special order only. Reynolds 525 Cr-Mo is the modern equivalent and, giv...

Agreed, exactly that happened to a friend of mine last week. She hit a shallow kerb stone at small angle and lost control. Bars apparently twisted around and I noticed the hinged bracket on the V-brake arm, into which the noodle fits, was damaged as the noodle had tried to pull through it. Having ha...

Just to complicate things, I experienced terrible shifting problems with my front mech (Deore XT M750 - 9 speed) when I replaced the original Deore chainset with one of the Spa Cycles triples a few years ago. It really wouldn't work with the 10-tooth difference between the top and middle 'rings but ...

…. If the cracks were oriented laterally across the width of the rim I'd probably bin it.... why? Wheel rims have nigh-on this exact thing (a radial crack) anyway if they have a pinned joint. If the wheel has a reasonable tension in it there is a compressive force holding the rim together of approx...

Have to admit I've got the same issue with the rear wheel in my summer bike, a Giant Rapid. I marked the ends of the cracks a while ago - there are 4-5 cracked spoke holes - and have been monitoring for growth since. The cracks have grown a bit but as yet there's no sign the spoke eyelets are starti...

Assuming the caliper has only one moving pad, then using the manual adjuster on the static pad, screw it inwards a few turns, then re-set the caliper position as before by pulling the brake on, then releasing and re-tightening the caliper mounting bolts, then back off the adjustable pad a few turns ...

Seems odd the original chain has worn so quickly in just 600 miles, but you could always keep it and use it again on the transmission when the chainrings and sprockets are fairly worn, and the chain will run smoothly. I use 3 chains in rotation and replace each after 1000 miles, then go back to the ...

In a similar vein, I recently bought an eBay bleeding kit to bleed the basic hydraulic front brake on my commuter bike only to find that most of the kit was useless as the syringes and plastic tubes intended to bleed the caliper won't fit as there is no bleed nipple on the caliper. There just seems ...
