1. FIZIK Carbon Rail saddles can fit on the Carbon and Super Wings using the optional Carbon Rail adaptor kit. www.fizik.it
2. ISM Adamo saddles can take all of our XLAB Wings, except the DELTA WING. If you are using the Carbon Sonic or Sonic Wings with the seat clamp in the rear post hole, then these 2 carriers need to be inverted to avoid the downwards tail on ISM saddles.
