I have a 09 Trek Madone 6.5 that has a seat mast and want to use a Romin Pro saddle. The clamping mechanism in the seat mast is only designed to clamp "round" seat rails. The seat rails on the Romin Pro saddle are "oval." Does anyone know if Trek has a different clamp (that supports oval rails) or anyone have a trick to make this work? I really want to try this saddle.
Trek has a couple alternate sets of "ears" for your seatmast cap. If your rails are 7mm x 9mm, you want Trek part #406923. If your rails are 7mm x 10mm, you want #421564. These should set you back about $12 a set.
