Features
Tubeless Ready rims
Bontrager TLR (Tubeless Ready) Road is the first fully integrated tubeless system for the road. No tubes mean there’s no pinch flats, allowing you to run lower tire pressure. With lower tire pressure you can increase traction, control. and comfort, reduce fatigue on you. Best of all, the tire sealant seals up punctures as soon as they happen!
Rack & fender ready
Built-in mounts make it easy to add racks and fenders for added versatility.
Low touring mounts
Touring-specific mounts stabilise loads for multi-day trips, with no additional hardware required.
Racks
Racks make commuting and hauling a practical reality, so it’s easier to go by bike.
Blendr stem
Bontrager stem technology lets you clip your gear directly to the stem for clean looks, maximum user friendliness.

Sizing & Tech
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
