L-TWOO RX12-Disc 2x12s Road Hydraulic Disc Brake Groupset — Features and Specifications
This complete 6-kit groupset covers every functional component a road cyclist needs: hydraulic disc brake levers, calipers, a front and rear derailleur, crankset, and cassette, all matched from a single trusted manufacturer for guaranteed compatibility. Road hydraulic disc braking uses mineral-oil hydraulic circuits that deliver consistent lever feel and modulation across wet descents, dusty gravel sectors, and high-heat mountain stages where rim brakes fade. Precision 12-speed shifting across the full 2x12s cassette range is achieved through L-TWOO’s indexed mechanical actuation system, calibrated to the same benchmark standards referenced by Shimano R7170 and R8170 groupsets so you compare with confidence. The derailleur body and lever internals use hardened alloy construction with surface treatments that resist corrosion and wear through multiple seasons of all-weather riding. Shop now at the official L-TWOO store for the best available price, complete set verification, and fast shipping on the full RX12-Disc groupset.

I have installed 3 ‘Ltwoo 1×12 mechanical gears, an Egr, an Erx, and now this one on my brother-in-law’s bike (yet to be installed). I think I’ll be just as happy with this as I am with the others, right?

Extremely well packaged. It looks pretty good. I will give an update after installation.
