New bike and insane death creaking from the frame after 700km. Time to get to the root of the issue.
Ended up changing the bottom bracket and headset to some choice upgrades from UK masters Hope Technology. Then serviced the XT Trail pedals and fitted rubber grommets on the cables.
Then stripped, cleaned, greased and reassembled the pivot bearings.
Finally stripped off the shock to find the bushes had been dry fitted. Greased and reassembled and creak gone. Expensive fix, but silent running and some smooth bearings to replace some graunchy old ones. Bottom headset race was particularly bad.
All done and just enjoying the rumble of chubby rubber on dry trails…
