It seemed inconceivable for us to have one without the other. The META POWER range is now composed of two platforms: the 29 and the SX (in 27.5). The name SX refers to the legendary COMMENCAL platform which has always been known for its downhill capabilities. The POWER 29 is pure performance. A beast on technical climbs with a disconcerting downhill ability. It's an ally to the person who climbs for their descents. It will help the rider through difficult sections which makes it easier to find flow in places there shouldn't be any!
