Shimano Deore MT620 two-piece crankset with DYNAMIC CHAIN ENGAGEMENT+
Shimano's two-piece Deore MT620 alloy crankset is built for trail and enduro riding, due to its tough materials and worry-free technology. DYNAMIC CHAIN ENGAGEMENT+ optimizes the narrow-wide tooth profile for consistent chain retention, and a steel direct mount chainring adds strength where the drivetrain takes the most stress.
What Our Gearhead® Experts Are Saying:
"DYNAMIC CHAIN ENGAGEMENT+ keeps the chain seated through rough terrain without needing additional retention hardware. The solid black finish works well for builds where a clean, understated drivetrain is part of the spec."
