I just went from 140mm to 160mm and offset from 51mm to 46 on a giant this evening, only tried it at the driveway fell pretty good. Going to the trail Sunday to a proper test
everytime i Got the Creak sound on my giant e I just have to loosen the seat clamp and tighten it again then it will be silent for the 100km or so. Don’t know why but just learned to live with it
I chance my gearing to 38 teeth sprocket and a 11-42 cassette. That’s the best thing I ever done. Still some decent topspeed and on the steep section the 42 teeth on level 2-3 sitting on the bike.
