It’s also made in the far east and sold over here
I seem to have had a thing for some of those 2k-2001 Cannondales. Had a Silk Tour (best proto-gravel bike and I instantly regretted selling), an F400, and F500 and an F900. Beautiful, chunky and very lightweight frames with hardly a visible weld. All made in Bedford, Pennsylvania, USA. Have no reason to doubt the Silk Road was the same. 2009 was the year they ceased US frame-production and shipped it Far East? Silk Road/Silk Tour weren’t in production by then I don’t think.
BTW that Planet X thing looks like my first ‘proper’ road bike after I mistakenly sprinted it into the back of a Ford Capri 😉
Still rode it with the bent tubes and interesting geo for another 6-7 years without further issues. Beauty is in the eye of the beholder. Saying that, I think that my Longitude is an ugly lump but it’s nonetheless a pretty good bikepacker/ATB
