external type bb,s questions

the torx type bit is for certain crank bolts i think

This is the type I have :

Mines not ice toolz but it is nigh on identical

cheap off eBay ;-)

its recommended that the frame shell is re-faced prior to fitting the cups, so that the bearings sit squarely to the crack axle. Needs a special tool to do it, so its probably a job for the LBS

WD Pro · Apr 14, 2011

Yes, I had read this before I fitted and made the decision to do so (even though the BB shell was fully CNC’d). I was fortunate enough to have free access to the correct park tools

It just cost me a burger and a pint in the pub after ;-)

that said, surely the cups will sit straight when done up to the correct torque?

got a superstar spanner for mine in the end works well enough

but i would go for a cup type next time

why so?

WD, that "Torx" bit fits the plastic preload cap on non-XTR Shimano cranks. XTR has a preload ring behind the LH crank arm, all the others have a cap threaded into the end of the axle, a bit like a headset

so you can use a torque wrench on it and it grips all the way round the bb cup too
