I recently upgraded my drivetrain to 11spd. Xt cassette, mech, and an xtr shifter with a kmc chain. Thing is its all brand new, the bike shifts and sounds fine in the stand but when I ride it and put torque down it creaks and makes such a disgusting and constant noise. It isn't the BB, Not the guide and the cassette is tight, it sounds like it coming from the chain ring area, which is also tight.
Help me out, If it is the chain sooner the better would help me with warranty. Thanks in advance guys
