Shimano Deore XT-M8120

The Shimano Deore XT FC-M8120-B2 crank features entirely new construction, using direct mount chainrings, special gear tooth profile for improved chain retention, and a 178mm Q-factor.

The Deore XT is designed for the rider who isn't afraid of aggressive trail riding, yet requires a rigid and lightweight design. The hollow forged crank maximizes power transfer while allowing you to save on added weight. Easily tunable and exchangeable with a single and double chainring, the Deore XT offers phenomenal performance without breaking the bank.
