I feel i’m coming to a decision after reading your post. I’ll get rid of this f&#% bike. Mine is almost 2 weeks in my LBS, they’ve painted the scratches on the chain stay, they don’t have a clue of what is going on, just tightening randomly nuts and bolts.. this issue is posted here for almost 5...
Pool, didn’t quite get you... I’ve followed until the chainring rubbed the frame. After that you wrote something that seems to be the cause, but i couldn’t understand... can you explain?
Hum... you are correct. When you sit, the clearance increases. But don’t count on that... i made the same observation and the thing rubbed even when seated on the bike, with the rear shock compressed...
Sure! Its a valid point. I'm not saying Trek after sales is bad (to be honest this is my first Trek), just reinforcing how strong Specialized's is (this I know from facts). But what amazes me the most is the fact that this must be a geometry problem... not rocket science. An eletric bike is not...
You will be between chainring rubbings and motor failures... How we use to say in Brazil, "if you run the beast catches you... if you stay the beast eats you".
The Specialized support seems to be unbeateble though... I´ll be towards Levo if I were you.
It is
It is pretty strange though... the flexing would occur, at least in theory, when you charge it. And when you do it and the rear shocks compresses, the clearance increases... the thing is close when there is no weight what so ever on the bike. Tomorrow it will go to my LBS, But i have to...
Right, tks.
Ive checked the torque on the main pivot and it was loose. The wrench moved half a turn to reach 30Nm. After torquing it, the chainstay remained alarmingly close to the chainring. And when a say close, I men less (much less) then a mm close. The motor seems to be firm on the frame...
Guys, just rode my third trail with my “almost” new 300 kms rail 9.8 and got the same scratch on the chainstay... have you came to any conclusion? Here in Brazil the fix will be touching up the scratches and “find out” what is happening... seems they are pretty lost...
