DT Swiss EXC 330 29" 30 mm Rim

The 29-inch DT Swiss EXC 330 rim is the ultimate weapon for enduro racers and bike park riders who refuse to compromise. Designed for custom wheel builders, it combines the exceptional obstacle-clearing ability and speed retention of the 29" format with a reinforced carbon construction that withstands the hardest impacts.

Its strength lies in its impact-resistant carbon lay-up, specifically designed to dissipate energy when the rim bottoms out on rocks or roots at high speed. With its 30 mm internal width, it provides the ideal modern profile for stabilising large enduro tyres at low pressures. It eliminates tyre squirm in berms and delivers rigid, surgical handling precision when the gradient gets extreme.

What does the ASTM 5 classification mean for this rim? It is the highest approval level in cycling. ASTM Category 5 certifies that the EXC 330 rim is designed for extreme terrain, high speeds and big jumps. It is officially approved for downhill (DH) and bike park use, providing an enormous safety margin for intensive enduro riding.

Is it suitable for a high-performance electric mountain bike? Yes – in fact, that is one of its best uses. With a total weight limit of 130 kg and ASTM 5 certification, it easily handles the extra weight and motor torque of electric enduro mountain bikes. Its carbon stiffness transforms the handling of often-heavy e-bikes when shifting weight from side to side.

What are the tyre requirements for the EXC 330? Its hookless profile requires Tubeless Ready or Tubeless tyres with strong beads. For enduro riding, pairing this rim with tyres featuring reinforced casings (such as Double Down, Super Trail/Gravity or Downhill) is strongly recommended, so you can safely run low pressures and make the most of the exceptional grip offered by its 30 mm internal width.
