Pinion C-Line Gearbox (6 / 9 / 12 speed) Electronic Smart Shift

Pinion C-Line Gearbox Assembly (C1.6, C1.9 & C1.12) Upgrade or replace your drivetrain with a genuine Pinion C-Line Gearbox Assembly. Designed for frames built around the Pinion gearbox platform, the C-Line delivers exceptional durability, low maintenance, and smooth, precise shifting in a fully sealed gearbox. Unlike traditional derailleur systems, the Pinion gearbox places the drivetrain's weight centrally within the frame, improving handling while protecting the transmission from rocks, mud, and trail impacts. The sealed design also minimizes maintenance and keeps shifting performance consistent in all riding conditions. This listing is for the gearbox assembly only.
