If your Trek has a standard type seatpost (male post fits into a female hole in the frame), then the dual-position seatpost will fit your bike. 

If your bike has a "Ride-tuned Seatmast" (commonly found on higher-end Madone/Domane/Emonda models) then it is not compatible with your bike. Unfortunately, we do not currently have plans to create this version of the seatpost.
