hi guys my wife and i have recently began riding again . bought properly fitted specialized rockhopper disc from LBS for mixed road and trail riding .. after 2 weeks of riding my wife has bruises on her legs just below the knee on the inside of her leg in the exact same spot on both legs . she is obviously rubbing the bike while pedaling. we would appreciate any input on what may be the cause and any changes we can make in her form .. she is very athletic ,runner , in great shape and we really want to keep riding we enjoy it so much .. thanks for any ideas or help !!
