The Duo Modulus Carbon Rim are hand made using Toray High Modulus carbon fiber. This one piece construction allows for a stronger design that still weighs practically nothing. Originally designed with racing in mind but these days smooth park riders are even getting into the carbon game. The Modulus went through some rigorous testing by USA BMX #1 pro of the year Jeremy Smith, and by 3 time national champing Vet Pro Tyler Brown. Duo also gave you options for whether you are riding traditional style brakes or a disc setup, or potentially a fully brakeless setup if you so choose.
