L-TWOO electronic groupset

The same know-how, at a fraction of the price

L-TWOO is based in Zhuhai in southern China and describes itself as China's largest manufacturer of bicycle groupsets. It started out with mechanical MTB groupsets and in 2023 launched its first wireless electronic road system, the eRX.

Thanks to in-house development and manufacturing, L-TWOO groupsets do everything the big brands' electronic groupsets do: fast, precise shifting, hydraulic disc brakes and set-up from your phone. The difference is in the price, not the performance.

Electronic road groupset from 162,000 Ft. Wireless gravel groupset from 170,000 Ft. MTB groupset from 13,000 Ft.

L-TWOO eRX shift/brake lever

Engineering know-how from the school of the big names

L-TWOO's founder, Liu Chunsheng, spent ten years at SRAM before setting up his own company. That experience is in every groupset: the founder learned the trade at one of the world's leading drivetrain manufacturers, and the company has built its systems by following its own path.

Developing a new groupset takes them three to four years. The result is an electronic groupset that the international cycling press takes seriously: both BikeRadar and road.cc have covered it, comparing it with Shimano 105 and SRAM Rival.

L-TWOO eRX shift/brake levers on the handlebar

Wireless shifting for the road

The eRX and eR7 shift at the touch of a button, quickly and precisely, even in the rain and cold. The rear derailleur communicates wirelessly with the shifters, both derailleurs are powered by a single battery hidden in the seat tube, and the groupset, brakes included, weighs about the same as a Shimano 105 Di2.

  • eRX – the flagship, with carbon levers, the racer's choice
  • eR7 – with aluminium levers, the most affordable way into electronic shifting

L-TWOO eRX-TT time trial handlebar

One push of a button, even from the aero position

In time trials and triathlons every second counts, and you don't want to reach off the extensions to shift. The wireless shift buttons of the eRX-TT and eR9-TT sit at the ends of the extensions, while the base bar carries hydraulic brake levers with shift buttons, so you can shift from the aero position and while braking.

  • eRX-TT – the time trial version of the eRX system, for maximum performance
  • eR9-TT – aluminium version at a lower price, with the same wireless shifting

Gravel bike with an L-TWOO groupset

Gravel and trail, made simple

On loose gravel, in mud and on steep climbs, simplicity matters most. The eGR is a fully wireless 1x12 gravel groupset: there are no cables between the shifters and the rear derailleur, and the rear derailleur handles cassettes of up to 52 teeth. The T series mechanical groupsets, with their clutch-damped rear derailleurs, keep the chain in place on the roughest terrain.

  • eGR – wireless 1x12 gravel groupset with hydraulic disc brakes
  • TX, T9, T7, T5 – 12, 11, 10 and 9-speed MTB groupsets for every level

L-TWOO hydraulic disc brake

Hydraulic brakes that bite in every situation

L-TWOO electronic groupsets come with hydraulic disc brakes, so you don't need to source a separate braking system. Hydraulic brakes deliver strong stopping power with little effort at the lever and stay predictable on gravel, in the rain or on long descents.

  • Hydraulic disc brakes – part of every electronic groupset, with front and rear callipers
  • Complete groupset – shifters, derailleurs, battery and charger in one package
Setting up the L-TWOO APP on a phone

Keep what you already have

The electronic road groupsets work with 10, 11 and 12-speed cassettes, so you can keep your current cassette, crankset and wheels. Set-up, button mapping and updates are handled from your phone with the free L-TWOO APP, and a full charge takes just a few hours.
