Well, it says 4.1lb for frame, fork and headset. That's pretty light for steel accounting for both fr./fork. The geometry is pretty true track, and with the BB drop at 45mm, that means it'll be one of the highest BB's you can get for a production track frame. I don't know of anything higher actually. Basically what that means is a higher center of gravity and more pedal clearance in corners, and a different "feel" for how it turns through corners.
