Good, better, best…supreme. What comes next?
The aero section on Jet 4 FR wheels is molded from a stiffer and lighter 1K fabric, saving 30 g per rim. Flamme Rouge Sonic hubs are built to the same exacting tolerances as regular sonics, but reduce weight with a carbon hub shell and forged titanium ratchet ring. Abec5 bearings are used for durability and low rolling resistance. Ti skewers are lighter than stock steel ones. The Scandium alloyed rims on FR wheels are lighter, stronger, and stiffer than unalloyed models.
