Shifting problem

[Catrin]

Glad you got it sorted - and that you've got such a great LBS.

Who would have thought about this 'trimming' thing on her own....guess that is one of the things that happens when you, basically, teach yourself how to ride and really don't know anyone who did before joining TE and hiring a personal trainer

Does this apply to all bikes, or is it related to having trigger shifters?

Generally, most bikes with both front and rear derailleurs, because of the way the chain moves side to side.

It depends somewhat on your setup. The longer your chainstays, for example, the less the angle of the chain to the FD cage will vary. I rarely need to trim when I've got everything in just-so adjustment, but I think I'm in the minority there.

Thanks! I had vaguely heard something about trimming but really didn't understand what/how/why. Of course it didn't help that the RD had apparently been bumped out of position - but he fixed that as well. Education and tweaking, all at no extra charge
