LTWOO eR9-TT Electronic Groupset

2*10/11/12Sp, but can also be used 1X

This groupset is engineered specifically for the geometry and bar configurations found on TT and triathlon frames, with cable routing and lever placement optimized for TT and tri bikes where aerodynamics and rider position are non-negotiable. Electronic precision shifting via L-TWOO’s motor-driven derailleur delivers instant, repeatable gear changes that stay calibrated over the full race distance, eliminating the mechanical drift that affects cable-pull systems under load. The replaceable battery system uses a user-accessible cell format so you can swap power in under a minute at transition or before a stage, rather than relying on a fixed internal charge. APP programming and tuning connects via Bluetooth to let you adjust shift timing, synchronize front and rear derailleurs, and update firmware from any smartphone — no proprietary hardware required. Buy now from the official L-TWOO store to access the best price, confirm full manufacturer warranty, and benefit from secure worldwide dispatch.
