I have three Treks; Rail 7 G2, EX 8 G5 and the current offering EX 8 G6. Absolutely love my Rail, and it has been flawless for about 150 hours now.
On both my Rail 7 and EX 8 G5, I had the usual creaks and squeaks, however with a little cleaning and lubing of pivots, those were all easily solved.
HOWEVER, with my 3 month old EX 8 G6, I am chasing a squeak/creak noise that I have not been able to cure. I have a very long list of things that I have done, Parts that I have switched over from my other Treks, Parts that I have removed just to eliminate potential reasons for noises. I am almost positive it is coming from the headset area. I have had that apart a few times, cleaned, greased, reassembled, but with no improvement. The lower bearing is just a standard 1.5" 36° x 45° cartridge bearing. It does however have a strange wear mark on the outer race where it contacts the pressed in bearing cup. A local 30year Trek technician looked at it and said it was just fine. He said to just reassemble with grease, and torque the 4nm screw to 7-8nm before tightening the stem pinch bolts and that would quieten it down. Sadly that made no difference. Open to thoughts and questions. Thank you, Andrew Cooksey
