Maximus handlebars are the first, modern, 31.8, oversize bars designed specifically for BMX racing. When used with the new BOX Delta stems (currently the only BMX stem on the market compatible with the Maximus bars), you get the stiffest cockpit available. The added stiffness significantly improves bike handling while putting more upper body power into your pedal stroke. Custom made from the highest quality 4130 chromoly, the bars feature proprietary 13-butted taper from 22.2 Ø at the grip area to 31.8 Ø across the lower bends. Available with and 8- or 8.5-inch rises, they have 6-degrees of back-sweep and 2-degrees of up-sweep. The black powder coat finish will keep them looking good for a long time. Meets or exceeds ENBMX standards. They fit all stems with 31.8 Ø clamp diameter, including the BOX Delta Stem.
