I recently purchased an older Cannondale CAAD4 for my wife in 52cm. She loves the bike and the power it gives her but she still has problems with her arms and hands. She has problems reaching the brakes and shifters so I thought a shorter stem with more of an angle would help the reach. It did somewhat so we went out for a ride Saturday and about 15 miles in she started to say her forearms and hands were hurting. So I studied her riding position and noticed her shoulders were tight into her body and here elbows were locked due to the narrow bars? So I compared my handle bars to hers and mine looked to be a good inch or more wider.
My wife is a lot broader on top than most women and her bike is 52cm so the handle bars are 42 compared to my 44's. So my question would wider handlebars help her any? Or is something else wrong?
