I've been riding it only on the track, and it leaves quite a bit to be desired as a race rig only, but this was definitely not what surly had in mind when they made this frame, so I can't really complain.
It's a great machine for riding around town and longer road rides because it has the STA and bb drop of a road bike with the steeper HTA and lower rake fork of a track bike, and the frame is super comfy
