Belt Drive Centertrack Front Sprocket 130Bcd 55T

What Our Gearhead® Experts Are Saying:

“I’ve ridden the CDX system year-round through all kinds of conditions, and this 55T front sprocket is at the heart of it. Lightweight aluminum keeps things responsive, and the CDX interface is super dialed for high torque and long mileage. It’s a ‘set it and forget it’ kind of upgrade for serious commuters or gravel builds.”

When we’re logging daily miles and hammering through unpredictable weather, we demand components that perform quietly, cleanly, and without complaint. The Gates 55T 5-bolt CDX Front Sprocket is just that—precision-crafted for maximum belt-drive efficiency and minimal maintenance.

This sprocket is machined from premium 6061 aluminum, finished in a sleek black anodizing that adds corrosion resistance while matching the clean aesthetic of CDX drivetrains. Designed for a 130mm BCD, 5-bolt crank, and engineered for 11mm pitch CDX belts, it seamlessly fits most belt-compatible frames and cranksets. Whether you’re riding in city traffic, logging long gravel tours, or commuting year-round, the CDX series delivers the strength and silent precision to go the distance.
