Ltwoo GRT 1 x 12

Full hydraulic carbon 1x12 speed hydraulic disc brake groupset

L-TWOO was founded in 2013 by Chunsheng Liu. The brand name literally means ‘blueprint’ in Mandarin. Mr. Liu had worked as a senior mechanical engineer for 20 years before the start-up, 10 of which were spent with SRAM.

The 1x12 hydraulic groupset is an all-new design for road and gravel application, featuring:

• "Continuous Release” technology: Gives you the ability to release up to 4 gears at once.
• "Ice wings" cooling system: Includes Ceramic Piston technology, minimising heat transfer in the brake line.
• Unique 'EggRoll' brake pad cooling design: Increases the heat dissipation area by up to 300% when compared to traditional brake pads.
