I've seen lots of threads before about going down a size with the likes of a Chris King Devolution, but what options are there if you want to run a 1 inch steerer in a one and a quarter / Evolution head tube?
Oh, forgot to say, if you have a 1 1/4" crown you can shim that to take a 1" steerer using a Pace crown shim and a pace 1" steerer tube. Works on Pace and Manitou 1 crowns (obviously not on crowns where the steerer is press-fit in)
