Backbone Rim, Alloy, 27.5"
The Backbone is a bomber 32mm internal 27.5 trail mountain bike rim. We improve the stiffness, strength and longevity of a wheel by using an asymmetric (ASYM) rim design than improves spoke tension balance by up to 30%. On the trail, this translates to balanced handling you can rely on. With a 32mm internal width it’s perfect for wide trail tires.
Drilled for external nipples. Disc specific rims.
All Astral rims are Tubeless Easy for tire installation that you can set up with a floor pump.
Custom builds available! Any hub, any spec, just contact us with your special project. We’ll make it happen. Services also available to dealers.
