FEATURED TECHNOLOGY 

HOLLOWTECH II  - Providing the best balance of stiffness, strength, weight and rotating 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, you want light, 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 & rotating performance in a lightweight and beautiful crankset design.
High Precision Sealing
Moreover, HOLLOWTECH II crankset has a high-precision sealing in the bearing area to increase durability maintaining the excellent rotating performance for long periods.

Frequently Asked Questions

The Shimano BB‑RS500 is a threaded Hollow‑Tech II bottom bracket that fits 68 mm‑70 mm shells, uses sealed cartridge bearings and a new seal design for durability, and is intended for Shimano Tiagra and other Hollow‑Tech cranksets.

Will the BB‑RS500 fit both 68 mm and 70 mm threaded bottom‑bracket shells?

Yes, the BB‑RS500 is sized for 68 mm‑70 mm threaded shells, so it installs directly into either width without any spacers.

Is this bottom bracket compatible with my Shimano Tiagra crankset?

It is designed for Shimano Tiagra and any other Shimano Hollow‑Tech II crankset, so it will work perfectly with those crank arms.

How long can I expect the sealed cartridge bearings to last on Indian roads?

Under typical riding conditions in India, the sealed bearings usually last up to 5,000 km before noticeable wear, provided they are kept clean and lubricated occasionally.

Does the new seal construction handle dust and mud common in India?

The BB‑RS500 features a refreshed seal that resists dust and moisture, making it suitable for Indian traffic and monsoon conditions, though regular cleaning after rides in heavy mud is recommended.

How can I be sure the BB‑RS500 I buy is genuine Shimano?

Buy from an authorised Shimano dealer or reputable online store, check that the packaging bears the Shimano logo, a clear model label (BB‑RS500), and a matching serial number; counterfeit units often lack the proper seal and branding.
