Chaplin,

what I believe PeteC is referring to the is an optional "alignment tool/ring" that you can purchase from Lynn at Trigo Headquarters... The tool/ring is a "must have" in my book.

The tool is a small ring, same diameter as the hub/adapter, looks like it was machined from an adapter, and you use it to make sure the screw-on pins are aligned perfectly with the tool, before attempting to put the wheel on. Without it, you "might" end up having to struggle to get the wheels on the first time or so. If you don't buy one; usually you can find a person closeby with Trigos that might let you borrow one.

Good Luck.
