Rigid and efficient, it's perfect for both trekking and city exploration. The gear's special tooth shape improves chain engagement and retention, ensuring smooth riding even on rough terrain. Dynamic Chain Engagement+. Hollow forged crank increases power transmission without adding weight. Hollowtech ll. Only compatible with LINKGLIDE shifting system. DYNAMIC CHAIN ​​ENGAGEMENT+. Gear tooth function. The DYNAMIC CHAIN ​​ENGAGEMENT+ by SHIMANO has a gear tooth profile designed for single chainring configurations for XC, enduro and trail riding. This prevents the chain from coming off and allows for smooth pedal operation even on uneven terrain. No matter which gear the chain is in, tight engagement helps reduce wear and tear. A high-dimensional balance of rigidity and lightness, and high rotational performance. This is his Hollowtech II technology concept, which explores the crankset from various angles in order to convert the rider's power into propulsion. The rigidity of the crank part has a large effect on pedaling efficiency. In addition, as the number of rotations increases as the distance travels, the lightness of the crank is an especially important factor. Rigidity and lightness have always been contradictory elements, and finding the right balance has long been a challenge. Hollow Tech uses unique forging technology to make the crank arm hollow, reducing weight while maintaining the necessary rigidity. In Hollowtech II, the BB axis has an integrated structure, achieving an even higher level of balance between rigidity and lightness of the entire crank section. The width of the left and right bearings has been widened, suppressing deflection of the bottom bracket shaft, providing stability and transmitting pedaling force with high efficiency. The Hollowtech II crankset was developed by pursuing the balance of stiffness, lightness, and rotational performance in every detail. High precision sealing. In addition, the Hollowtech II crankset features a high-precision seal on the bearings to improve durability and maintain high rotational performance for a long time.
