Electronic shifting for time trial and triathlon bikes

The L-TWOO eRX-TT brings the eRX system to aero bars: the wireless shift buttons go on the extension ends and the hydraulic brake levers with shift buttons on the base bar, so you can shift from the aero position and while braking.

Together with the eRX front and rear derailleurs, hydraulic disc brakes, battery and charger, the set forms a complete, unified system. Setup is easy with the L-TWOO APP.

Crankset, chain, cassette and brake rotors are not included.

L-TWOO eRX-TT 2x12 Electronic Time Trial Groupset – Ultralight shift buttons for the extensions

Ultralight shift buttons for the extensions

The shift buttons are powered by a built-in cell, so no wiring is needed. The expanding internal clamp holds them securely in the extension ends, and they weigh only about 40 g.

Shift from the aero position without moving your hands – in time trials and triathlon that means seconds.

L-TWOO eRX-TT 2x12 Electronic Time Trial Groupset – Brake lever with shift button and comfortable grip

Brake lever with shift button and comfortable grip

The wide, thick grip area of the hydraulic brake levers gives comfortable, confident control, and the built-in shift button lets you shift while braking and cornering.

The 19–22.5 mm clamp fits most time trial base bars.

L-TWOO eRX-TT 2x12 Electronic Time Trial Groupset – eRX derailleurs and integrated hydraulic disc brakes

eRX derailleurs and integrated hydraulic disc brakes

The set uses the eRX front and rear derailleurs: asynchronous multi-shift, over-travel technology, in-house motor and Type-C charging.

The integrated one-piece caliper is lighter and stiffer, and better heat dissipation gives consistent braking.
