knowing that a simple, enjoyable ride can make an incredible difference for a cyclist’s commute, the ‘efneo’, developed by the migaszewski family business, is a 3-speed front gearbox that shifts gear much more quickly. this sleek solution features an efficient and light chainring which rotates at three different velocities on each gear, and replaces the old, pesky and ugly front derailleur. its gaps are not too big, yet not too small, making it ideal for single-pace riders who desire a comfortable journey. the invention, from stefan migaszewski, is easy to install and is the only 3-speed system on the market, as all others are either 2-speed or require a specific frame, and is seeking funding to develop it further, through its indiegogo campaign.
