Rigid and efficient, it can be used for trekking or exploring on the town.
The gears have a special toe shape that improves chain interlock and retention for smooth riding even on rough terrain.
Dynamic Chain Engagement +
Hollow forged crank for enhanced power transfer without adding weight Hollow Tech ll
Compatible with LINKGLIDE Shifting System only.
DYNAMIC CHAIN ENGAGEMENT+ Gear tooth function
DYNAMIC CHAIN ENGAGEMENT+ by SHIMANO has a gear tooth profile designed for single chainring configuration for XC, Enduro and trail riding.
This allows for smooth pedal operation even on uneven terrain. The chain bite securely no matter what gear is, reducing wear and wear.
High dimensional balance of rigidity and light weight, and high rotational performance. It is the concept of Hollowtech II technology that pursues cranksets from different angles to convert riders power into propulsion.
The rigidity of the crank is greatly involved in pedaling efficiency. Also, the longer the distance the more rotation, the lighter the crank is particularly important.
Rigidity and light weight are always conflicting factors, and long have been asking for the proper balance.
Hollowtech hollow crank arms with unique forging technology to reduce weight while maintaining necessary rigidity. The Hollowtech II also features a one-piece BB axis to provide an additional high dimensional balance of stiffness and light weight across the crank.
The left and right bearing widens to reduce the deflection of the bottom bracket shaft for stability and transfer the pedaling power efficiently.
The Hollowtech II Crankset was developed to balance rigidity, light weight, and rotational performance.
Precision sealing The Hollowtech II crankset also features a precision seal on the bearing for improved durability and long lasting rotational performance.
