hub gear


Hub gears or internal-gear hubs are sophisticated gear systems commonly used on bicycles. Hub gear systems generally have a long and largely maintenance-free life though some are not suitable for high-stress use in competitions or hilly, off-road conditions.


(hub gears) Also called "hub gearing," or "internally geared hubs" these rear hubs (the centermost part of the wheel) have the gearing system inside.


(Hub Gears) Hub gears have a gearbox built into the rear hub, sealed away from the elements. Gears are engaged and disengaged by a pushrod from the end of the hub. Hub gears are heavier than derailleurs, but need a lot less maintenance and are more forgiving of misuse.
