Two years of R&D, extensively lab tested, raced and proven with some of Australia's best riders; the Australian made Tammar race rim is here. It boasts better handling, improved tyre support and grip to meet the needs of the elite gravity enduro racer to the weekend trail thrasher.

 The optimum balance of torsional stiffness and global wheel stiffness need to be met to offer the perfect performance. Our Tammar rim design profile can absorb impact energy and improve tracking and tyre traction. Better traction means faster riding.


Tried and tested in the harsh relentless Aussie conditions

White Angle Set

   The rim is a solid profile, similar to motocross rims, which, from a carbon engineering perspective, means the fibres are supported correctly through an optimised laminate. This gives the rim it's superior toughness out on the trails. This leaves the current traditional MTB rim design, which is a carry over from aluminium rims and manufacturing processes adapted from carbon road rims.


Race tuned carbon lay-up for improved tracking and traction

White Side set

To optimise the perfect rim we reviewed four key design elements (Learn more) and what BC developed was the first wide platform solid profile carbon rim in a hookless bead format for 27.5"/650b.
