In the market for a new crank and bb as i am fed up with the clunking and loosening of the truvative huss that came on the bike ( Spec SX trail for freeride/alpine trips)

Was wondering does anyone have any strong opinions on which to buy. Raceface has 1 yr guarantee on BB and lifetime on cranks, have got xtype on my other bike and is OK.

Shimano lighter, cheaper but dont know about warranty. Also suggests to be fitted by LBS first time?

I'd go with Saint. Tried and tested by downhillers all over the world, I don't think I've ever heard of any breaking. I've used some Diabolous stuff in the past, stems and seatposts, and they seemed a bit heavy and overbuilt. You don't really see a lot of Diabolous stuff around, it's mostly Thomson for stems and posts and Saints for cranks.

FWIW I was about to switch to XT for downhill until I changed to a bike with an 83mm BB and they wouldn't fit, plenty strong enough tho'.
