SHIMANO SLX M7100 Boost 52 mm crank 170 mm

DYNAMIC CHAIN ​​ENGAGEMENT +, with LED position light: It is a special gear toothed profile designed for use in single plate configurations for XC, enduro and trail. Increase chain retention and facilitate pedaling, even on rough terrain. Chain retention of any gear will reduce abrasion and wear. - HOLLOWTECH II, Providing the best balance of stiffness, strength, weight and turning performance. The concept of HOLLOWTECH II technology has focused on the production of an excellent crankset to maximize the cyclist´s power transfer. The stiffness of the crankset guarantees the effectiveness of pedaling, while its light weight, a key element of the crankset, makes the cyclist improve his performance over longer distances, in which he must pedal more. Naturally, SHIMANO has worked to achieve an optimal balance between the stiffness requirements, in addition to achieving a light weight. HOLLOWTECH technology is an ultralight hollow crank arm created by SHIMANO, with the company´s own forging technology that also allows stiffness to be maintained. The addition of the HOLLOWTECH II technology integrates the bottom bracket with the right crank arm to achieve greater rigidity and save weight and thus obtain a high dimensional balance. The outer bottom bearing system provides better weight distribution and greater pedaling stability, to achieve a more efficient transfer of power. The HOLLOWTECH II crankset has been developed to achieve the optimum balance of stiffness and spin performance in a lightweight and attractive crankset design. High precision sealing. In addition, the HOLLOWTECH II crankset has a high precision seal in the bearing area to increase durability and maintain excellent turning performance for long periods.
