Pièces de groupe

Individual drivetrain components sold outside a full groupset: rear derailleurs, front
derailleurs, shifters and brake-shift levers, mechanical and electronic wireless alike.
Buying single parts lets you replace a crashed derailleur or upgrade shifting one piece at
a time instead of paying for a complete group. Affordable 11 and 12 speed derailleurs and
shifters are widely cross-compatible with mainstream road and gravel drivetrains.
