Efneo Bicycle 3-Gear Front Gearbox

Front derailleurs are finicky little contraptions. Never tune one again with Efneo’s 3-gear front gearbox, a clean, low-maintenance alternative to the most bothersome bicycle component in existence. Equipped with a concealed planetary gearbox, it’ll fit on any frame designed for a tapered square axle bottom bracket and smoothly shifts between three gears under load or even at a standstill using a one-cable paddle shifter. Plus, it works equally well with rear derailleur-equipped bikes as to add a few gears to a fixie.
