Description

Looking to build the ultimate race bike? Then there's no doubt that you will be running carbon rims and here are their options for your pro bike. Available with a braking service and without (non-braking) surface, these rims are not only super strong and stiff, they are light!

We've built hundreds of BMX race wheels with carbon rims and we very rarely ever see them fail, or buckle. Their ability to take big hits astounds us, and offsets the higher initial investment as they can take a case that would see you throwing away a alloy rims and fully rebuilding a wheel.

Answer BMX have led the carbon revolution in BMX racing with their Dagger forks being on the scene for over a decade. They know what it takes to build a dependable, performance orientated carbon BMX component.
