Product Details

Ready for wherever the journey takes you, Topstone Alloy distills the spirit of Topstone Carbon into a rugged, ever-ready aluminum frame. Whether you're exploring routes less travelled or accelerating your commute, go beyond with the durable, dependable Topstone Alloy.

Gravel is all about adventure, so we've equipped Topstone Alloy for getting out there with the reliable confidence only a Topstone can deliver. An all-new fork offers three mounting points on each leg, with a plethora of frame mounts for weekend jaunts or big bikepacking trips. The secret to a great bike is in its geometry. We've dialed in the rider position to be upright enough for comfort and control on technical terrain, yet forward enough for speedy, drop-bar efficiency.

Two rings, endless possibilities. This Topstone is built to tackle the toughest gravel rides with Shimano GRX 400 2x10-speed shifting and a SmartForm C2 Alloy frame. With ample tire clearance and mounts for racks and gear, it’s engineered to meet the demands of adventurous riders and unpredictable routes.

  • Lightweight SmartForm C2 Alloy frame w/ full carbon fork
  • Reliably precise shifting from the Shimano GRX 400, wide-range, 2x10-speed gravel drivetrain
  • Powerful, controllable braking from Shimano’s GRX400 hydraulic disc brakes
  • Selle Royal SRX Open saddle balances supportive padding and a pressure-relieving central channel for performance comfort
  • See Geometry image in gallery for size information.
