Looking at the specialized epic and the titus X. Suspension designs seem almost identical. Is the brain an upgrade? I have ridden a titus just not an X. I am currently on a hardtail 29er and looking to add a full suspension 26er to the quiver for more technical races. I'm 5'11'' with a 33'' inseem. Any ideas with fit? I will be racing Xterra tris as well as XC. Thanks in advance.
