Brompton 12-Speed Chain Tensioner Nut and Washer

Designed for the 12-Speed Drivetrain

The Chain Tensioner Nut and Washer is part of the rear drivetrain assembly used with Brompton's 12-speed system.

As a dedicated replacement component, it is intended to match the hardware used with the corresponding 12-speed rear wheel and chain tensioner assembly.

The correct component should always be used when servicing or replacing drivetrain hardware.

Easy Identification

One of the key identifying features of the 12-speed nut is the small hole in the nut, which allows the gear indicator chain to be visible.

This feature can help distinguish the 12-speed component from other Brompton chain tensioner hardware.

Compatibility

The Q103581 Chain Tensioner Nut and Washer is intended for Brompton 12-speed configurations using the corresponding 12-speed rear drivetrain.

It may be found on 12-speed configurations of models such as the C Line, P Line and T Line, depending on the specific model specification.

For the correct replacement part, always check the bicycle's drivetrain configuration and Q Part number before ordering.

  1. Ensure the bicycle is securely positioned before starting work.

  2. Use the correct Q103581 replacement component.
