Shimano BB-RS501 Bottom Bracket in Silver

Season:2022

Brand:Shimano

Code:CR9141

The SHIMANO TIAGRA bottom bracket uses a new seal construction for long-lasting performance.

The concept of HOLLOWTECH II technology is focused on producing a superior crankset which will maximize a rider's power transfer. The rigidity of the crankset ensures pedaling efficiency while its weight, a key element of the crankset, aids in cycling longer distances over which the rider needs to pedal more. Naturally, SHIMANO strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank.

HOLLOWTECH technology is an ultra-lightweight hollow crankarm created by SHIMANO with the company's own proprietary forging technology that also maintains rigidity. The addition of HOLLOWTECH II technology integrates the bottom bracket axle with the right crankarm for more stiffness and a weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedaling stability allowing for more efficient power transfer.

The HOLLOWTECH II crankset has been developed by pursuing the optimum balance of stiffness and rotating performance in a lightweight and beautiful crankset design.
