L-TWOO GRT 1x12 Full Hydraulic Disc Brake Gravel Groupset (CARBON)

The world's first ever full hydraulic carbon 1x12 speed mechanical disc brake groupset from China!

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, giving you the ability to release up to 4 gears at once along with the new "Ice wings" cooling system( including Ceramic Piston technology), minimising heat transfer in the brake line. The unique 'EggRoll' brake pad cooling design increases the heat dissipation area by up to 300% when compared to traditional brake pads.
