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.

Engineering & Design Highlights
Integrated Carbon Cockpit
A high-modulus carbon integrated handlebar and stem (400×90mm) with full internal routing. The one-piece front end cleans up the cockpit and cuts drag, locking you into a confident, aero-efficient riding position.
SHIMANO 105 Drivetrain
A SHIMANO 105 hollow crankset drives efficient power transfer for crisp, race-ready shifting. Choose WheelTop GEX 1×13 wireless, SHIMANO 105 R7120 2×12 mechanical, or SHIMANO 105 R7170 Di2 — each tuned for fast, reliable gear changes.
Deep Carbon Wheelset
Deep-section T800 & T1100 carbon rims (W28 × H58mm) on ultralight 54T-ratchet hubs with carbon spokes, wrapped in MAXXIS Pursuer 700×28C foldable tires. The aero-profile wheelset holds speed on the flats and stays composed in the bunch.
