The TriMax Carbon OS flat base bar is a lightweight foundation for a custom aero bar set-up on a triathlon or time trial bike.

Highlights

  • Full carbon construction with a UD carbon finish
  • Aero sections with a 3:1 aspect ratio, legal for UCI competition
  • Generous straight 31.8 mm centre section for most clip-on extensions
  • Internal cable routing with ports for Di2 wiring
  • Flat, 0 mm drop
  • 410 mm wide, 205 g (Vision)

Clean and fast

Vision shaped the wings for aerodynamic efficiency within UCI rules, and full internal routing keeps cables and wires out of the wind for the cleanest possible lines.

Compatibility & fit

Clamps into a 31.8 mm stem, and the straight 31.8 mm centre takes most standard clip-on aero extensions, such as Vision's TriMax Carbon Clip-On. Our workshop can fit the bar and extensions, route your cables or Di2 and set up your position.

Vision guarantees its alloy and carbon handlebars against defects in materials and workmanship for two years from the date of purchase. Bent bars and damage from bar ends or clip-on bars aren't covered. For warranty support, return the product to Tune Cycles and we'll manage the claim with KWT Imports, Vision's Australian distributor.
