Faster gravel. Cleaner lines. Built for riders who refuse to compromise.

The G5 is the evolution of our acclaimed G3 - a gravel bike that goes harder, faster, and further. In Alpine White, every aerodynamic detail stands out: the D-Type seatstay fairings, the integrated FIDLOCK storage pod, the wafer-thin head tube. This is a race machine designed for the pointy end of the peloton, equally at home on a gravel race course or a weekend epic.

Patented D-Type Aero System. The G5 borrows the same D-Type seatstay design proven on Winspace's T1600 aero road bike - asymmetric tube profiles with an integrated fairing and seatstay tail fin. Combine that with a full ACR internal cable system and ultra-thin head tube profile, and you have a gravel frameset built to cheat the wind without sacrificing an ounce of off-road capability.

What makes this worth it

D-Type Aero Seatstays

Borrowed from the T1600 aero road bike - patented D-Type seatstay profiles with integrated fairing and tail fin reduce drag without compromising vertical compliance on rough gravel.

FIDLOCK In-Frame Storage

A secure FIDLOCK magnetic storage box is built into the frame - carry tubes, tools, and nutrition without a frame bag cluttering your cockpit or adding wind resistance.

57mm Tyre Clearance

Room for 57mm front and 52mm rear - whether you're running fast 700×40c road rubber for race day or 700×50c for an adventure weekend, the G5 handles it.

T47 Threaded Bottom Bracket

T47-68mm threading means no press-fit creak, easy serviceability, and compatibility with SRAM DUB, Shimano, and Campagnolo cranks - all with a standard BB tool.

Universal Derailleur Hanger

UDH (Universal Derailleur Hanger) compatibility means replacement hangers are available worldwide, and you get plug-and-play support for all SRAM eTap AXS rear derailleurs.

Full ACR Internal Routing

Every cable and hose disappears inside the frame. The ultra-thin head tube profile and ACR internal routing system keep the front end clean, quiet, and aerodynamically honest.
