The gel pads just add more stuff in the engine compartment. I suggest you either get the same seat you are using for normal cycling or get a real good set of shorts or bibs.... Stay away from the high-end catalog shorts offered from Performance, Nashbar, Pricepoint, Supergo etc....... Find a place in your area or online that deals with RACING stuff.... I have a set of Santini bibs and love them... I bought them at a race and it was one of the best purchases I have made.
