speed drive

The speed drive is always the right solution, when wanting there to be no extreme marginal values (neither a very high gear nor a very low one) but however when a wider more general gear ratio is desired. Speed drive is wireless, low-maintenance, ideal for Single Speed and Fixed Gear bikes and a useful expansion of every hub or chain gear. Speed drive is also available as a Brompton version.
