New progressive geometry
For quick, nimble handling that still keeps you stable and in control on rougher descents.
Tyre clearance
Lots of clearance means you can run meatier tyres (700x45 mm or 27.5x2.1") for tackling chunkier gravel and terrain.
Tons of mounts
Integrated frame bag and mudguard mounts make it easy to carry gear and water.
Shimano GRX
Shimano GRX was designed from the ground up for gravel adventure. With its gravel-specific ergonomics, optimised gearing options, rugged reliability and quiet, stable drivetrain, GRX sets itself apart from the rest of the component world.
Don’t forget your pedals
This bike doesn’t come with pedals because you’ll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style.

Wider gravel-specific tyres provide better traction and more stability while riding on gravel or dirt tracks.
Flat Mount disc brakes
All-new Flat Mount disc brakes are more elegant, lighter, smaller and cleaner than traditional disc brakes, providing superior performance and stopping power under harsh conditions.
Tubeless Ready rims
Bontrager TLR (Tubeless Ready) Road is the first fully integrated tubeless system for road wheels. When you go tubeless with TLR, you can run lower tyre pressure for increased traction and comfort without the threat of pinch flats.
Blendr-compatible stem
Bontrager Blendr stem technology lets you clip your gear directly to the stem for clean looks and maximum user friendliness.
