Vintage pretty much rules out 130 in the back unless you cold set from 126 to 130. Start with a 6 speed which are 126. You could get your new bike set up with the original 6 speed and see if that is enough. If you are determined to run 11 speed and you like your Gunnar, look at Milwaukee bikes. They're made by Waterford and will do everything you want. People think mine is C&V.
