Yes, you’re right about releasing the belt before removing it, I guess I would have done that anyway.
Thanks for the tip about being cautious with the last screw - I have a torque key and some loctite, so I’ll manage. It’s no rocket science but you’re right that these procedures are not complete enough for the layman to do the work easily.
I’ll report again as soon as I have mounted and tested the new wheels. I know what to expect - I just hope my bottom agrees with my choice, since apparently it will be a slightly tougher ride
