If so I would expect them to be compatible.
Yes, I'll be going for the ten speed I believe. If the 5700 is much more than the 5500 than I'll take the cheaper option if there is no large difference.
I'll also be buying the groupset together, shifters, cassette, etc. included. There should be a link in my first post that goes to an eBay auction, so like that.
Thank you for all the help!
