SHIMANO's DYNAMIC CHAIN ENGAGEMENT+ is a special gear tooth profile designed for use in single chainring setups for XC, enduro and trail. Increases chain retention and makes pedaling easier, even on rough terrain. Chain retention of any gear will reduce abrasion and wear.

Providing the best balance of rigidity, strength, weight and turning performance. The concept of HOLLOWTECH II technology has focused on producing an excellent crankset to maximize the rider's power transfer. The rigidity of the crankset ensures pedaling efficiency, while its light weight, a key element of the crankset, allows the cyclist to improve his performance over longer distances, where he will have to pedal more. Naturally, SHIMANO has worked to achieve an optimal balance between competing needs for stiffness, while also achieving light weight. HOLLOWTECH technology is an ultra-lightweight hollow crank arm created by SHIMANO, with the company's own forging technology that also allows rigidity to be maintained. The addition of HOLLOWTECH II technology integrates the bottom bracket axle with the right crank arm to achieve greater rigidity and save weight and, thus, obtain a high dimensional balance. The outer bottom bracket bearing system provides better weight distribution and greater pedaling stability for more efficient power transfer.

The HOLLOWTECH II crankset has been developed to achieve the optimal balance of stiffness and turning performance in a lightweight and attractive crankset design. High precision sealing. Additionally, the HOLLOWTECH II crankset has high-precision sealing in the bearing area to increase durability and maintain excellent spinning performance over long periods.

Shimano XT Mountain Crankset, Model M8100 12 speed. The new DEORE XT 1x12 crankset features HOLLOWTECH II arms with integrated bottom axle and hollow arm. The chainrings come with a Dynamic Chain Engagement profile, whose narrow/wide teeth are key to better chain retention and facilitate a smoother and quieter transmission. For secure mounting of the chainring, the crank has a Direct Mount system that simplifies changing.
