Problems ? I am going to supose to do something similar i have a devinci spartan and a lyrik/26 dont have enought money for theblyrik 27.5 Thanks for the info (y)
I haven't ridden it yet. My friend is running 27.5/26 on his V10, so I'll post what he says here! But general rule of thumb, 65* headangle on a 650b front wheel will feel about the same as 64* on a 26er.
