In reply to Rog Wilko:
My other half has a similar problem - she has really tiny hands - some sort of squirrel DNA I think.
anyway, she has 105 levers on her bike and was struggling for reach, despite having girl specific bars. I got some shims from Evans and they reduce the reach, but her main problem is her hands are actually to small to operate the gear change action!.
Campag levers suit smaller hands so I might try her on those.
Ther are quite a few threads on the various biking forums on this. Singletrack had a few and some of the US forums had a few.
