The new Selle Italia Flite idmatch L1 saddle is the latest version of the hyper successful Flite line. This version retains the near 200-gram weight of the original Flite and relatively flat shape. The firm shell is 10% carbon shell plus comfortable yet firm padding. Refinements include a slightly wider width that is carried through the nose. This makes the saddle a little more comfortable when you are on the gas and up near the nose. There is also a very slight channel for a touch of relief. Selle Italia uses standard 7mm tubular titanium rails for compatibility with virtually any seatpost clamp.
