so i got my brand new dream bike with full xx. riding it around the pavement to test it out and the one issue i seem to have is that i'm overshifting the front derailleur from the small to the big chainring. 3 times out of 10 i'm throwing the chain off the big chainring onto the crankarm. obviously there's a learning curve, but is that all there is to it? do i just need to find a lighter touch or is there some problem?
