20% Carbon Fiber, as light as 6.5 grams. Standard bolt spacing (64mm C-C), sizes from 10-90mm with larger sizes available on request. 40mm and larger have a optional compartment to place an Apple AirTag (not included).
See our other BTA options for angled and aerodynamic versions. BTA Bridge & Computer mounts coming soon.
Note: Removing material from center actually makes the riser heavier, so these are made to maximize their strength to weight ratio. The riser can be ordered without an air tag compartment, saving 2.4grams.
