L-TWOO GRT12-Disc 1x12s Gravel Groupset Features and Specifications
The L-TWOO GRT12-Disc delivers a complete 1×12 speed drivetrain solution purpose-built for gravel riding, pairing a wide-range 12-speed cassette compatibility with a single-chainring setup that removes front-shifting complexity on mixed-surface routes. Carbon fibre construction is used across the lever bodies and derailleur cage, cutting system weight while maintaining the stiffness needed for accurate power transfer and responsive shifting under load. The hydraulic disc brake system provides consistent, modulated stopping force in wet, muddy, and dry conditions, giving you the braking confidence that cable-pull systems cannot match at speed on loose descents. All five kit pieces are matched and calibrated as a unit at the factory, so installation produces a groupset that shifts and brakes cohesively from the first ride without extensive individual adjustment. GRX-benchmark performance standards guided the engineering tolerances throughout, meaning competitive gravel and adventure cyclists get a trusted, high-specification package at a price that makes the upgrade accessible through the official L-TWOO store.

The groupset is amazing and it’s exactly as shown in pictures, with the new brakes. If you don’t mess up the set up you don’t even have to bleed the brakes since both lines and shifters are pre-filled with oil!
Shifters + oil inside + cable are 500 g, derailleur is 287 g

Very beautiful gravel gear set. I am very satisfied with the purchase. The set was packed in a simple cardboard box and each individual part was individually wrapped in two to three bubble wrap bags. It couldn’t be better. Thank you.

I still need to mount it on my partner’s bike but I’ve been happily using it on my gravel bike for a year and a half.
