BDop Cassettes took several years to design and to test. This included 2 years as a sponsor for an Elite cycling team in Asia that placed on the podium in races from Taiwan, Malaysia, Korea, Hong Kong and Japan.
They are meticulously machined from single blocks of high quality alloy or steel. 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 watch the video below. We have since added a new alloy model: Shimano/Sram 11-30T which has quickly become our best seller.
We also now offer two Shimano/Sram steel models in 11-25T and 11-28T.
