Twitter R18 Racing ED

Engineered for the podium, the Twitter R18 (Racing Edition) is a full-carbon aero road racer built around a high-modulus T800 & T1000 monocoque frame with a slippery aero profile and fully internal cable routing. An integrated carbon handlebar-and-stem cockpit, deep-section carbon wheelset, and aero-racing carbon seatpost are tuned to hold speed on the flats and stay composed in the bunch. Offered with WheelTop wireless and SHIMANO 105 mechanical or Di2 drivetrains, the R18 lets you pick the shifting platform that matches your race day.

Key Features

  • High-Modulus T800 & T1000 Carbon Frame (R18 Disc, Thru-Axle 12×142) with aero design and full internal cable routing.
  • Integrated Carbon Handlebar & Stem (400×90mm) with full internal routing for a clean, aerodynamic front end.
  • Deep-Section Carbon Wheelset — T800 & T1100 carbon rims (W28 × H58mm) on ultralight 54T-ratchet hubs with carbon spokes.
  • Three Drivetrain Options — WheelTop GEX 1×13 wireless, SHIMANO 105 R7120 2×12 mechanical, or SHIMANO 105 R7170 Di2.
  • Hydraulic Disc Braking (160/160mm) for consistent, all-weather control.
  • RS Racing Carbon Saddle & Aero Seatpost with MAXXIS Pursuer 700×28C foldable tires.
