Efneo, a Polish company run by a family, is bringing bicycle components to market to make a cyclists life easier. We covered their idea of an internally geared crank two years back, and they are now gearing up to start taking pre-orders for the x3 gearbox crank and the Active silent hub. While an internally geared crank and a silent hub are not new ideas, Efneo hopes to bring them to market for all types of bikes, and with the help of crowdsourcing.
The x3 crank is an internally geared, shiftable crankset that can be installed on any bike. While the idea is not new, as it has been seen in Hammerschmidt, Schlumpf and the Metropolis Patterson, the x3 is the first one to incorporate 3 speeds, not just two. Similar to other systems, the benefits are touted as being able to offer instant gear changes, being able to shift without pedaling and cleaning up the drivetrain so there is less maintenance. Offering a range similar to a 28/40/50 crank is impressive, and it seems to be able to mount without any strange parts or adapters.
