BDop Cassettes took several years to design and to test. This included 2 years as a sponsor for Elite cycling teams in Asia that had riders on the podium in races in Taiwan, Malaysia, Korea, Hong Kong, and Japan.
They are meticulously machined from single blocks of high-quality alloys and steel. They deliver excellent shifting under all conditions.
Consideration has also been given to how they engage with alloy freehubs. The resulting design spreads the load over a wider area and stops the cassettes from damaging alloy freehub bodies.
To understand our cassettes a little further, you can follow the link below. We have since added two new alloy models: Shimano/Sram 11-30T and Shimano/Sram 11-32T. We also now offer two Shimano/Sram steel models in 11-25T and 11-28T.
