Time-trial worthy speed with road crank rigidity. The Flow slices efficiently through the turbulence behind your front wheel and fork, resulting in a 6 second time reduction on a 40km time trial or 15 seconds over an IM bike split at 200W average power. A worthy upgrade for your TT, triathlon/duathlon or aero road ride.
- Rotor crank arms are stiffer than forged designs due to Trinity Drilling System
- 3 full-depth holes lighten each crank arm, the box-trellis shape that remains has greater rigidity and better stiffness to weight than hollow-tube construction
- Chainrings not included
