Shop all gearAll-new rim design
The 4.6mm hook wall thickness increases strength and durability, while the shallower 27mm depth increases vertical compliance and helps better absorb impacts.
Strongest we’ve ever tested
Bontrager’s all-new Line wheels are the strongest carbon wheels we’ve ever tested—of any brand. Line wheels are built to stand up to the rigors of the trail and keep you rolling, whatever comes your way.
Fewer flats
The wider hook bead offers a 300% larger outside hook radius, which means more surface area in contact on a sharp impact to help prevent pinch flats.
Line rims are built from proven OCLV Pro Carbon for an optimized blend of weight, strength, and durability.
Rapid Drive 108
Each model features Rapid Drive 108 hubs, which have 108 points of engagement for quick accelerations and confident pedaling through even the most demanding terrain.
Carbon wheels can give your ride an instant upgrade in speed and handling—and when you choose Bontrager, your investment is protected. All Bontrager carbon wheels are backed by a lifetime warranty for the original owner.
