He'll need a left nut removing spanner, a right nut removing spanner, and the appropriate spanner holders.
He'll then need a wheel transposer (and holder, brace, and, is he's playing safe, belt).
He might avoid having to use a chain retensioner or track end measurer, but he will need left and right wheel nut replacer spanners, and replacer spanner lube gun, and holders.
Then he'll need a wheel alignment jig, and ChainDeSlackerâ„¢, and a wheel spin rotator.
Plus any parts?
