My 575 started to develop a creak under power from the rear of the bike (only happens when going up very steep hills using a big gear, on or off the saddle and it also occurs when i'm only pedaling with the left or right leg).
The debug procedure this morning went as follows:
1. Inspected and greased post and clamp and and cleaned seat rails (the creak happens off the saddle also but I figured cleaning and inspecting the post and saddle rails is never a bad thing).
2. Cleaned and lubed all cable stops.
3. Cleaned and lubed rear QR
4. Cleaned and lubed all chainring bolts.
5. Cleaned, greased and loctited dogbone link bolts and torqued to spec
6. Cleaned, greased pedals threads
Unfortunately the creak is still there, although not as noticeable as yesterday. I only have 3 remaining things to check.
a. Bottom bracket
b. Main pivot bolt
c. Rear wheel (primarily the spokes).
I'm thinking it's the BB since at times, it creaks under every stroke (using different gears) but I was hoping it wasn't since the BB would be the 1 hour fix and I was already running late for work. I only had a chance to check the crank bolts.
The only thing I have changed recently is the cassette (XTR 960) and the chain (SRAM 971), both of which I've installed per instructions and the chain was degreased and lubed twice (using MotoX lube).
