The Dynamic Shaft Drive System is a unique “chainless” drive system for transferring power smoothly and efficiently from the cranks to the rear wheel of a bicycle. Using specially-made spiral bevel gears, sealed bearings, a carbon-steel shaft rod and precision-machined aluminum housing, this shaft drive delivers a smooth, clean, efficient, durable and low maintenance operation. The Dynamic Shaft Drive System (SDS) is ideally suited for bike share bicycles, e-bikes, folding bikes and city bikes. When combined with an internal hub, bicycles with the Dynamic SDS provide versatility, all-weather durability and low maintenanbce for recreation, transportation and commuting.
Our revolutionary Versa Road Bike Components create new design possibilities and add new levels of performance and versatility to chain driven bicycles utilizing Shimano's advanced 8-speed internal hubs. With the new Versa road shifter and cranksets, you can develop internally geared road bikes that surpass every other internally geared bicycle on the market in terms of light weight, performance, handling, versatility and durability. Whether for fitness riding, commuting or touring, the Versa components help create bicycles that are simpler to operate and simpler to maintain.
