Shifting problem

[Catrin]

I apparently fixed it last night without realizing it It is too hot to ride tonight so decided to clean my chain when I came in, and while working I TRIED to get the chain to rub - but it refused to do so

I am still having them look at it when I pick up my saddle, but I seem to have done more than I knew - Thanks!

Took my bike to the LBS to get his new saddle - and asked them to adjust my shifters. Apparently the RD was not hanging right, he said part of my problem was the chain was actually hitting the RD occasionally.

In his opinion - and I am sure he is right - because I don't trim properly when needed in shifting that it got things out of adjustment - but the off-center RD wasn't helping. I did not really understand this and he took some time to explain trimming with the trigger shifters when needed (any time I hear the chain).

If all bikes are like this, then I start to understand why my Trek shifted so badly the last time I rode her - this is the first in-depth discussion I've had on this and why it matters.

I like my LBS very much - they don't treat me like an idiot and do very good work.

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
