The sixc riser is an old favourite, winning the ‘best carbon bar’ accolade in our last group test. Upping the clamp diameter to 35mm has enabled Race Face to make this new version 15mm wider but even lighter (220g for our 10mm rise sample).
On the bike, the extra chunkiness disguises the fact it has a full 800mm span. It’s a comfortable shape, with eight degrees of backsweep and five of upsweep, and higher 20mm and 30mm rises are available if required. The 10mm version suited our 29er test bike just fine though, keeping the front end low and providing plenty of steering leverage to offset the extra inertia of the big wheels. It feels slightly stiffer than the 31.8mm version, though still with that trademark carbon buzz absorption. In fact, we ended up fitting thicker grips after a particularly rocky ride to provide a bit of extra comfort.
