Commencal launches the 29-inch downhiller on the market

A huge fuss was made at the start of the season about the large wheels in the Downhill World Cup. Commençal also let its athletes ride the 29-inch prototypes of the "Supreme DH" downhill model throughout the season. The mountain bike manufacturer from Andorra is now launching the "Supreme DH 29" as a complete bike or race kit.

The 2017 racing season is considered a turning point in downhill sport: 29-inch wheels were used in the Downhill World Cup for the first time. However, in the shadow of brands such as Santa Cruz and Trek, other brands also opted for the large wheels - including Commençal. The engineers of the bike brand from Andorra redesigned the Supreme downhill frame to 29-inch wheels and added more reach, stiffer rocker arms and sturdy enduro bearings, which are also connected to thicker axles. Despite the larger wheels, the "Supreme DH 29" still offers 205 millimetres of suspension travel - quite a mouthful.
