I had these wheels removed from my 2017 Cannondale Scalpel Si when it was being built.  This auction includes both front and rear wheels, Schwalbe Racing Ralph tubeless ready tires, and the tubes.  The wheels are ready to be converted to tubeless.  The carbon rims measure 23mm internally and 29mm externally.  Front hub is Cannondale Lefty.  Rear hub is ready for a SRAM cassette using an XD driver cassette body, with a 12 mm through axle.  The rear hub has a 39 tooth 4 pawl free hub for fast engagement.  Both hubs are 6 bolt disc compatible.  The rear wheel is built with the Cannondale Ai offset for their modern MTB's, but could be re-dished for a standard drive train.    The wheel set weighs 1472 grams.  Good luck bidding.
