The Shimano 105 5800 11-speed freehub will not work with Dura Ace 7850 hubs. We do sell the replacement Dura Ace 7850 freehub body here:

Unfortunately this freehub will not fit Alex hubs and is designed specifically for Shimano 105 5800 hubs and Shimano wheels that are based the 5800 hub.

While we don't carry the freehubs for Alex wheelsets you might be able to get one here: http://www.alexrims.com/contact-us-americas/

The Shimano 105 5800 freehub body will not work with Claris hub.

Your wheel will not work with 11-speed road.

canteau · Answer

This freehub body is specific to the Shimano 105 5800 series hub. There currently isn't an 11-speed road option for the Shimano XT M785 wheels.

canteau · Answer

While it may fit Shimano does not list this part as a "B" fit. We can special order the proper freehub body assembly for the RX31 wheel. Shimano's part number is Y44Y98040.

canteau · Answer

Most likely not, unless Bontrager is using a Shimano 105 based hub. While we are not a Trek dealer, we do service customers Trek bikes some of which use Bontrager Race Lite wheels. Some versions of the Bontrager wheel line use a DT Swiss freehub body and other use a proprietary freehub that is only available through a Trek dealer. If you don't have a local Trek dealer, give Trek's customer service number is 1-800-585-8735 a call with the serial number of the wheels and they will point you in the right direction.
