Box One Chromo Triple Taper Race HandlebarCustom made from the highest quality 4130 chromoly, Box One Handlebars feature a proprietary 13 butted taper from 22. 2mm at the grip area to 31. 8mm across the lower bends. The added stiffness significantly improves bike handling while putting more upper body power into your pedal stroke. That means getting out of the gate and down the first straight faster and accelerating quicker out of the turns. ###section### Product Specs Rise: Multiple Options
