Product Details

The Overfast Bielas GR Aero Carbon are the Ti24 GR version of Overfast’s aerodynamic crank arms: a 24 mm Shimano-standard axle, 325 g ±15 g, and an aero profile for road, time-trial, and triathlon builds.

  • 325 g ±15 g — carbon-fiber arms with an aerodynamic profile.
  • 24 mm titanium axle (Ti24) — Shimano standard, 148 mm Q-Factor, and 44 mm chainline.

  • Eight lengths starting at 155 mm — 155 and 157.5 mm extend the range below the Light range.
