I want to make the gears on my 14 yo (youth A) daughters bike more suitable.
It currently has a standard double 53/39, and a 12/27 cassette.
She is pretty strong and MOST of the time this is fine, but she really could do with some lower gears. In events she can't use the higher gears anyway.
My plan is to swop the double for a compact 42/34, this will avoid big jumps in ratios, give her the lower gears, and still use the double shifters.
Does this sound sensible - or is there another can of worms in there??
