Hi to all. I have a M2S Ultra HT bike with a Bafang M620 mid drive. The bike came with a 40T chainring and a 11/34 cassette. I think I'd like to slow down the low end to make the bike better when climbing on rocks and ruts. I don't care about top end.
Can anyone recommend a supplier / part number for something like a 5 bolt 130 bcd 34T that would be suitable for this torquey bike?
Thanks,
Allen
not sure exactly on that motor, it depends on the chainring offset if its going to work with your chainline and cassette. simply switching to a smaller chain ring often does not work, with the bbshd and bbs02 at least, since the offset is poor when you go less than 40 or 42T on the front ring. youll need to do some research
