Can someone tell me what size seatpost clamp the Genius has? I have a Spark and would like to replace the factory seatpost clamp with a Hope clamp. The clamp on the Spark is a 38.2, but the Hope website does not list anything sized that large. Chain Reaction Cycling however lists a 38.5 Hope QR clamp on their website (but Hope does not). The CRC site indicates that the clamp is for the Scott Genius, so I am wondering if the Genius has the same size clamp as the Spark?
