Hub adapter with a hole large enough to slip over the disc mounting boss. Requires measuring hub dia. and buying the correct kit. Can probably use the kit rag joint if you grind out the hole large enough to slip over the boss. Good luck https://www.amazon.com/Adapter-Chain-Sprocket-Motorized-Bicycle/dp/B0CWTLVPSN/ref=mp_s_a_1_4?crid=1Q3ILES16WGUP&dib=eyJ2IjoiMSJ9.rDwJLJaUgPio4iJ3Nm3ehws5eUBG7__CFbSCxEVWst9wApx-m4z6dfv_QCEVFs1RJwfNGUfGGYYJRUYd7Z95nfOUM9r8AEv_2pa7NJVYjyK42tcWuSrLj_zpV62alDjxpFQoLENFazepouIlCkm5ffUTGYDG77WYq5BYSKPsUCF2HQLkY1aD2GMdydafHsLZpGoMu8rh5zTRF7uLbrwQ_A.uzjNpppFGYt361CRYZbaPy8HEIuEAZmrZTbRVBT6L5I&dib_tag=se&keywords=CDH+hub+adapter&qid=1776542987&sprefix=cdh+hub+adapter%2Caps%2C309&sr=8-4
