I have just fitted new shimano xt 9 speed rear cassette, new shimano 9 speed hg/93 chain and new raceface 9 speed 22/32/44 team chain rings, to my mtb.
problem is a crunching noise coming from the chainrings when applieing pressure up hills etc. I have fitted a new bb also thinking this was the problem but to no avail. Everything is tightened up correctly and the pedal bearings are ok.
What have i done wrong? are some of the components not compatible? any advice gratefully recieved. steve.

    what are the cranks? (make/model/year)

    and did you reset the front mech?

  • cranks are truvativ firex circa 2004/5 on a dawes mtb. i adjusted front mech slightly to suit the new rings.
