Is there a reason you would keep her bike with a 12 tooth front and not go to 13 and add to the rear?

 

i prefer a 13 up front too, but time and chain cutting were not an option at that point... only got to ride on sat and races were on sunday... we try to work on her bike as little as possible and spend time on ours[img]i/expressions/face-icon-small-wink.gif[/img]
