I assume the torque spec' varies with how/if the thread has been lubed (dry, oil, grease, anti-seize etc..) is a c. 20% tolerance enough to cover this?

i'd want to disassemble at least once a year to check the condition of the steerer anyway, so repacking the bearings whilst it's in bits is a no brainer..

maybe an error by one of the algorithmic ebay re-pricer tools?

are you 100% certain it's the front hub and not the notorious mavic squealing freehub bush?

that's very interesting. worth a gear in relation to what - speed, flex?
thanks

don't do it!
if by some miracle they are actually returned, they will be dirty, blunt, empty, damaged or broken...

are the metal bridges designed to fit recessed brake bolts?

that's food for thought. I'd settled on 0.7mm as a safe minimum

Thanks Mark. That is bloody brilliant! I've probably spent 10+ hours scouring the internet and trying to figure it all out. What confused the hell out of me was the two rear derailleur gears on the Brompton and how to factor that into traditional gearing apps. From the chart, a 38T might be the way...

see HERE
c. 6.5 & 20 mph

some of graeme obree's bikes are also set up like this.

2 sets of wheels. currently shod with 28mm GP4000's for winter and 23mm corsa speed's for summer. the roads are good around here - PFI roads contract.

moths certainly seem to like it. luckily they haven't acquired a taste for polypropylene yet..

took the risk - no interference..

thanks - look forward to the next instalment...
