The Most Compliant E-Bike Rated Bar On the Market.
This Carbon E-Bar is 20% more compliant than other carbon handlebars. That means more comfort and less fatigue on longer rides.

The patented oval profile minimizes arm pump with vertical compliance and maximizes steering response with lateral stiffness. The oval bar profile narrows to just 20mm to maximize vertical compliance. For reference, the thinnest portion of a traditional handlebar is 22.2mm.

The Carbon E-Bar has internal routing for Shimano STEPS switch units and it passes the stringent Zedler E-MTB Advanced Plus standard and the international DH standard (ASTM Cat. 5 Downhill).

  • The OneUp E-Bar features internal routing for Shimano STEPS switch units and all other switch units with a connector diameter less than 6.5mm.
  • The wire port diameter in the bar is 6.5mm and the minimum switch wire length required to internally route is 650mm.
  • Specialized, Bosch or Rocky Mountain remote power mode controllers cannot be internally routed through the Carbon E-Bar.
  • If you have a switch with a removable wire (EP8, E8000, E7000) you can install a 650mm or longer Shimano EW-SD50 (1st gen EP8, E8000 & current E7000) wire or the EW-SD300 (2nd Gen EP8 & E8000) wire.
  • The Orbea Rise does not have a handlebar mounted display unit as it connects to your smartphone. It has the EW-EN100 junction and removable EW-SD50 wire.
  • If you don’t have a removable wire on your switch, you need to buy a new switch with a removable wire (SW-E7000-L) with a wire length of at least 700mm.
  • Or you can add the EW-JC200 2 port junction and an EW-SD50 extension wire

You will require a stem that can accommodate a center wire port. Two-piece faceplate stems are ideal.
