The BB-RS500 Press-Fit is a suitable solution for cyclists looking for a bottom bracket Shimano reliable, easy to install and compatible with a wide range of pedal sets Shimano Hollowtech II.

A Press-Fit bottom bracket housing to the BB86 standard

The BB86 is a bottom bracket standard in which the cups are pressed directly into the frame.

Unlike a conventional threaded bottom bracket, the Press-Fit system therefore does not require a thread in the bottom bracket shell. The cups are inserted into the designated sockets using a press-fit assembly.

The standard BB86 is characterised, in particular, by a bottom bracket width of 86.5 mm for compatible road bike frames.

Before buying, it is therefore essential to check that the frame is designed to accommodate a gearbox BB86 Press-Fit.

Compatible with pedalboards Shimano Hollowtech II

The Shimano The BB-RS500 Press-Fit is designed for cranksets that use the system Hollowtech II with an axis of 24 mm.

This technology Shimano separates the axle function from that of the external bearings or those integrated into the housing, with a bottom bracket axle that is integral with the bottom bracket.

The BB-RS500 thus ensures rotation of the axle whilst maintaining a rigid and precise connection between the crankset and the frame.

Bearings designed for smooth rotation

The BB-RS500 bottom bracket uses bearings designed to ensure smooth rotation of the bottom bracket spindle.

A well-maintained housing helps to minimise friction and unwanted movement in the crankset. Conversely, worn bearings can cause play, creaking or a less smooth feel when pedalling.

Replacing the gearbox can therefore help to restore quieter and smoother operation of the transmission.

A solution for maintenance and replacement

The Shimano BB-RS500 Press-Fit is a practical solution for replacing a housing that is showing signs of wear and tear.

Before fitting, it is recommended that you check the condition of the bottom bracket shell, clean the contact surfaces thoroughly and ensure that the dimensions comply with the BB86 standard.

Fitting a Press-Fit housing also requires a suitable installation tool to position the cups correctly without damaging them.

Which bikes are they suitable for ?

The BB-RS500 Press-Fit BB86 is primarily designed for bikes fitted with a road frame or a platform that uses the standard BB86 and a pedal set Shimano Hollowtech II 24 mm compatible.

It can therefore be used for the maintenance or repair of many road bikes, as well as other bikes that use this combination of standards.

Compatibility must always be checked against the frame standard and the crankset standard.
