Removal tool included?

This item seems expensive - does it come with the removal tool?
No- it's sold as seen. You just need a 10mm hex wrench to remove/ install.

Is This Compatible Replacement For A Shimano Wh 6500 Ultegra Rear Wheel With An Ultegr 9S Cassette?
16 Dec 2016
Hi, unfortunately the freehub body for the WH-6500 rear wheel was a specific item for that wheel which has now been discontinued. According to Shimano this is not a compatible replacement so we would not be able to guarantee that this would work correctly.

Unfortunately this is not the correct free-hub for your hub, the compatible one you need is SJSC part number 6390. Any of the freehub bodies will be strong enough for use with HG61 cassette.
