This bar from US freeride/dirt company Deity has a full 28in width and 50mm rise. It's available in oversize 31.8mm or 25.4mm (tested here) diameters and it's stiff and strong.
The 9-degree upsweep and 9-degree bend mean it feels a little more relaxed than our usual RaceFace Diablous bar of choice (with a 4-degree upsweep and 9-degree bend).
The stem is a simple 50mm machined lump, with a 4x5mm bolt bar clamp, and two offset 5mm bolts to clamp it on to the steerer tube and keep it out of the way of your knees. The stem is available in both 25.4 or 31.8mm compatible
versions, and both the bar and stem are available in white, black and grey.
These two parts make a strong, good looking combination and are great upgrades for style-minded thrashers.
