Sibex Sports was a titanium bicycle frame and component distributor here in Colorado Springs who went out of business 2 or three years ago. The frames are manufactured in Russia (not sure exactly where). This is a 64cm version of their Czar road frame, sans decals. It's not light but there are some nice features that beefed this frame up for bigger riders like me. Since Spectrum Powder Coating is right here in town, I'm thinking of partial custom powder coat once I come up with a design.
