Why We Love It
Donnelly is well known for making exceptional tires. Donnelly's acute attention to detail and commitment to understanding the needs of riders and terrain demands for each respective discipline keeps them at the front. They've taken this same approach when developing the G//C gravel frame. This isn't just a "tweaked" cyclocross frame. When designing the G//C, Donnelly focused on a geometry and carbon layup that provides long mile comfort on chattery gravel roads. The handling is controlled and confident through loose conditions, fast descents and challenging turns. Generous tire clearance allows up to 700 x 45mm tires (or 650b x 50mm) to support your adventurous nature and a front derailleur mount allows you to continue to choose between 1x or 2x drivetrains.
  • Shimano GRX RX810 crankset w/ Stages Gen 3 Power Meter on the left crank arm
  • 700 x 45mm or 650b x 50mm tire clearance
  • Lightweight and responsive high-modulus carbon frame
  • 1x or 2x drivetrain compatible
  • Confident and capable gravel geometry
Master Mechanic’s Notes
  • New handlebar tape
  • Light scratches on the shifters, fork, crank arms, seatstays, chainstays, rear derailleur, & rims
  • Please Note: Power meters are typically aftermarket upgrades, and we cannot guarantee battery life, accuracy, or calibration
