Mint! Utterly pointless IMO, but mint!
All we need now is an efficient belt drive/internal gear system and we might just be able to claim the first genuine, practical evolutionary step forward in bike design since the safety replaced the ordinary.
dissregarding freewheels, freehubs, dereilieur gears, front mechs, about 10 different evolutions of brakes (shoes, direct acting, rod pull, side pull, U-brakes, single pivot, dual pivot, those funky bontranger/shimano dual mouting brakes, drum brakes and disk brakes on crossers/tourers for ages), cranks (1 pieces, cottered, cotterless, 2 piece), A-headsets, and SPD’s, yes this is the first evolution in bike design ever. :p
