I purchased an exe 9.7 in Nov 22. It was good for a week or two and then started creaking from the BB when under stress - sprinting, out of the saddle tech climbs etc. I have had it back to the shop 3 times. Lock ring has been set to 50nm, all pivots / linkages cleaned and lubed, motor bolts removed, greased and replaced. Each time, it rides fine for around 20mins, and then the creaking starts. Is there anything else that I could try to solve this issue? I love the bike, have 3 other Treks, but the creaking is chronic, really distracting, loud and there seems to be few answers. Runs a 160mm fox factory fork, and AXS Eagle. Any help appreciated.
