You have a broken or locked gear chain? - No panic!
The Jay Parts gear ratio HD is the upgrade! The wider, reinforced Morse chain and the special surface-hardened gears have been specially developed to ensure durability.
The gear ratio does not change, so no further adjustments need to be made.
We recommend having the conversion carried out in a specialist workshop.
