Our aero, deep profile FCC 47 carbon wheelset comes standard with our new and improved hub design, the "44" hub. A Beefier hub with bigger internals, featuring 108 points of engagement, help you generate more torque and transfer of power for out of saddle efforts. We upgraded to a 44mm ratchet rings and offer compatibility with Shimano Micro Spline 12-speed and Campagnolo Ekar 13-speed groupset. The "44" hub has been updated to include a slip-fit system to easily swap out end caps to accommodate, 15mm,12mm or QR axles, helping you "future-proof" your wheelset.
 
The FCC 47 features front 16 spoke radial and rear 20 spoke radial/2-cross configuration providing all the performance without sacrificing durability or speed. Disc brake option is radial/2 cross for both front and rear for strength and stiffness. They are designed to keep the rotational weight down and sustained speed up. Included is Spinergy’s exclusive CNC machined design, force-10 tapered hub with strong straight-pull spoke mounting and aerospace grade aluminum axle, which rolls on a Spinergy designed HADLEY® aluminum freehub body. Thru axle compatible options available.
