AGates Carbon Drive 70T CDX Chainwheelis a High performance, durable front sprocket for e-bikes and other bikes using Gates Belt Drive, aluminum construction, featuring a 130mm BCD (Bolt Circle Diameter) for 5-bolt cranks, designed for quiet, low-maintenance power transfer with specialized CenterTrack belts, replacing traditional noisy, greasy metal chains for long-lasting, clean cycling.
Key Features:
Brand: Gates Carbon Drive (often CDX series for high performance).
Tooth Count: 70T (70 teeth).
Material: Usually 6061 Aluminum, for strength and light weight.
Compatibility: Fits 130mm BCD (Bolt Circle Diameter) cranks (5-bolt) and works with CDX CenterTrack belts.
Design: CenterTrack guide ridge keeps the belt aligned.
Application: Ideal for e-bikes, touring, commuting, or off-road where reliability and low maintenance are valued over chain lube and noise.
Why Choose It?
Durability: Lasts significantly longer than metal chains (up to 30,000km+).
Low Maintenance: No lubrication needed; just occasional cleaning.
Quiet & Clean: Operates almost silently and doesn't attract dirt/grease.
Performance: Smooth, efficient power transfer for various riding styles.
Considerations:
Frame: Belt drives need specific frames with a split or opening to install the belt, as it can't be opened like a chain.
Tension: Requires precise tension and alignment, sometimes needing specialized tools.
Integration: Works best with internal gear hubs or single-speed setups, not derailleurs.
