GRT 1x12 Speed Gravel Bike Groupset Mechanical Shifting Hydraulic Disc Brake Package Components LTWOO GRT Right Shifter ×1 (Shifting cable included) LTWOO GRT Left Shifter ×1 LTWOO GRT Rear Derailleur ×1 ZRACE XG Calipers ×2 Options: LTWOO GRT Carbon Version LTWOO GRT Alloy Version Version Guide Design for gravel enthusiasts, the LTWOO GRT 1x12 speed groupset is available in both carbon fiber and aluminum alloy. Both versions share identical core functionality, differing slightly only in material composition, shifter refinement, and graphic design. Notice In order to avoid SHIMANO's patent, LTWOO's Hydraulic Disc Brake Caliper uses a 70mm spacing mounting seat, and then installs it through an adapter, so that not only the Caliper is heavy, but the adapter is also very heavy, and the most important thing is that for some frames It is still not compatible, so we replaced the Flat Mount Caliper of ZRACE XG, so that the whole set can reduce weight 120g! and can be compatible with all flat mount frames and Forks. And it can be installed on the frame of Post Mount and IS Mount through ZRACE's Flat to Post / IS Adapter. Shifter ( Carbon version) Material: Carbon fiber brake lever. Operation: Right: Dual shifter lever. Left: Brake lever only. Cables: Shifting cables included. Weight: Left: ≈214g Right: ≈280g Shifter (Aluminum alloy Version) Material: Aluminum alloy brake lever. Operation: Right: Dual shifter lever. Left: Brake lever only. Cables: Shifting cables included. Weight: Left: ≈235g Right: ≈305g Rear Derailleur Features a one-way mechanical damper system for a more stable chain on rough roads.

Max Sprocket: 52T Carbon Version Weight: ≈283g Alloy Version Weight: ≈300g ZRACE XG Calipers Extruded and machined from a single block of 7075 aluminum, eliminating caliper flex under heavy braking.
