so, I thought i had a bright idea and have been planning to use the Stan's ArchEX 3.30HD wheelset from my mountain bike on a gravel bike build. They're light, 21mm wide, and they are very reliable tubeless. It just occurred to me that the Shimano 5800 11-speed cassette probably isn't going to fit on the Stan's mountain bike hub. Am i right? Anyone have any suggestions? I don't see a Shimano 11 speed freehub on the Stan's site. I like this wheelset and i think it would work great on a gravel bike. Any advice would be appreciated.
