This is about a 2003 vintage titanium SIBEX (Siberian Express) 58 cm cyclocross frameset. Sibex was a Russian company specializing in titanium. I was told the geometry is the same as the Ridley CX bikes, and the numbers look like they do line up with the L size X-Bow...http://www.ridley-bikes.com/us/en/bikes/4/157/50/cyclocross/x-bow-20-1405a
58cm stamped on dropout, but looks to be measured center to top of seat collar. Top tube is about 55.5 cm.
The fork is a carbon Easton with very little usage. I'll include the carbon seat post, avid shorty 6 calipers, headset, and Dura Ace front derr.
I built the bike to ride gravel roads, and it rides incredibly, but it's just too small for me.
For sale locally @ $550 (the fork retails for close to 500).
