Tern HSD S8i: How to remove the back wheel | Nexus 8 hub gear
Published at : 23 Dec 2025
Probably of no interest to anyone except owners of a Tern HSD S8i or other bike with a Gates Carbon Belt drive and Shimano Nexus internal gear hub.
I have a broken part to replace and want to change to chunkier tyres for the winter months so this video goes through the process of disconnecting the gear cable, removing the back wheel, replacing the Cassette Joint Set, swapping over my tyres, refitting the back wheel and then removing and refitting the front wheel.
