Just what I needed. Have a carbon use ultimate seatpost on my gravel bike and decided to upgrade the old saddle to one with carbon rails, so needed to swap out the clamp for this one.
Great product, swift delivery. Happy customer.

Use this for my 2012 Cannondale synapse because I upgraded my seat to a carbon seat. This was a great modification and held up for my iron man. I highly recommend it if you need to upgrade your old Cannondale
