32 inches. Zero Apologies. Introducing the GT-1 i55 32. Built with the singular goal of taking the performance advantage of a larger wheel and turning it into a gravel bike that you actually want to ride.

•
450mm chainstays, a curved seat tube and 3D printed chainstay yoke designed for 32x2.2 tire clearance and a 46T chainring on a gravel groupset.
•

Our very own, Zero Components G32 gravel fork is the crux of the design. Fully integrated cable routing, ample tire clearance for 32x2.2, and 60mm offset to work with a wide range of sizes.

Zero Components - when the components you need don’t exist, you build them. Starting with our G32 and G55 gravel forks.
•
•
IS52 Headtube paired with the iconic Mosaic headbadge.
The GT-1 is a proven gravel race machine, with an Unbound XL win and an Elite National Championship already under its belt. 32” takes it to the next level.
The all new Berd Spokes Sparrow 50 Gold wheelset is the perfect combination on the GT-1 i55 32. It’s deep, it’s aerodynamic, and it’s light. Game on.

•
A double sided 3D printed chainstay yoke keeps the rear triangle as short as possible, even with the larger diameter wheels. 450mm chainstays give us exactly the tire clearance and chainring clearance we wanted.
Room for a 46T chainring on a gravel chainline (47.5mm).
The Zero Components fork is designed to integrate perfectly with the ENVE In-Route or Cane Creek HCR cockpit system.
Berd Spokes Sparrow 50’s X WTB (Wilderness Trail Bikes) Course 32’s in a 52mm size are a perfect race ready combo.
