mine is an 'urge' although I can't find a frame number as yet and I don't really know much other than its similar in paint and weld-ons to yours, but no stickers mentioning Columbus or the red discs on the top tube.
Good luck with yours!
I think the Urge has Fuji SL tubing rather than Columbus, and a lot of Sunns from this period seem to lose their oval top tube stickers, not sure why. But a lovely bike and definitely worth fixing up.
yeah your sid has 6cm longer atc compared with an obsys carbon, which is the most proper fork for this cool frame
got a couple of sunns myself, and don't ride anything but obsys carbons.. mmmm 32mm sweet travel
I would be tempted by a Obsyss carbon, but they seem to be rarer than rocking horse poo, and I have bad memories of the standard Obsyss on my Vertik - I swear a rigid fork would have been better as the damping or rebound on it seemed to remove any correlation between what you felt and the terrain underneath you. Is the carbon fork better or just lighter?
