I'm pretty sure I have the middle one W the guide pin, has worked on 6 different bikes since I bought it years back. If you can, take the wheel to the bike shop just ask and test fit the tool. -S
He is the tech guy and quite knowledgeable. When I had a doubt, he was kind enough to go to warehouse and take a video for me. Very helpful.
Before ordering these tools, you might want to contact your LBS because for them it's very routine and a tune up generally involves cleaning of the cassette. They can certainly fix this up.
Thank you for the suggestions.
My "local" bike shop is 50 miles away, so you can guess I end up trying to figure out most things on-line and doing it myself.
