It's a road bike with a mech hanger but just happens to have track ends, so it's road spaced - 130mm. You don''t get a fork with it, the welding looks grim on the few I've seen, and there's no mudguard clearance. Wouldn't be my first choice for a winter fixed bike.
As a TT frame, the geometry will be focused on a aero rider position, and the frame possibly stiffer than a road equivalent (mind you track frames often are too). Because of poor riding conditions in winter, I would personally go for the opposite for a winter frame.
ie one that allowed a more upright riding position (more control on slippy roads)
one that was more complient (less bumping = more control + more traction)

Just my thoughts.....
