some of the Norco Shore Hardtails are 1.5 steer tubes. Sweet looking bikes, usually with good specs already, and 'cause its Norco, they're pretty easy to find.
i admit that the pornking is a bombproof super bad ass frame, but IMO the seat tube angle is too weird. i think the geometry is a bit overkill... BUT what can i say as i own a soul cycle sluggo
