Bouwmeester Composites Tammar v4.8 wheels – first look
Two years in development, the in-house-made BC Tammar v4.8 carbon enduro race wheels were recently released by Bouwmeester Composites, a design and manufacturing firm in Adelaide, Australia that claims to specialise in ‘low-energy consumption’ advanced composite products.
Unlike double-walled designs borrowed from aluminium construction methods, the Tammar uses a solid profile. This single-wall construction is common in motocross and recent fat-bike rim designs and is said to provide increased impact resistance and spoke-hole strength.

A wide rim offers plenty of advantages on the trail
Combining a hookless bead design and a wide-rim platform allows a focus on tyre performance and torsional stiffness. And with this, the guys at BC believe to have created the perfect enduro/trail rim.
Interestingly, the rims feature front- and rear-specific carbon layups. An asymmetric spoke bed allows for more even spoke tension, with the nipple mounds angled to match the spoke path.
