Re: New wheels or rims

I've built up a couple of pairs of kinlin xr31s - rim thickness seems to compare with the archetypes. c. 1.6mm and they're just weighing in at sub 500g. they're tubeless compatible but gp4000s can be fitted by hand.

Re: Gilles Berthoud Aspin saddle

Worth the investment - and i'm 'careful'!
mine has small dimples after 10k miles, maybe a little spread, but no where near the extent of an unlaced B17 after similar mileage (even a good one).
it's comfortable enough to go totally unnoticed - the mark of comfort imho.

Re: Never using an adjustable torque wrench again!

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?

Re: Threadless headset servicing - would you bother?

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..

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

Re: New Brompton owner - gearing question

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...
