This is really great stuff. CarbonMike (www.carbonmike.sk) has created his own bike with the help of the Linkage software. The result is an excellent quality frame that you wouldn't tell it is homemade. The ride? Mike says:

"I like my bike very much, geometry is absolutely perfect for me. Suspension works pretty well. My suspension is VPP but it don't have real S-shaped path. It's because of the down link. I had serious issue about spacing (as *** /famous brand name hidden/ also have) and I don't like long chainstays so I did it like this. I made also that VPP logo. I used covering sticker (cutted on machine) and than sandblasted it (on block of flats balcony :)) Polishing was really hard, I spent tons of hours polishing. But I really like final result. Whole frame was relatively low-cost. I spent less than 588Euros (about $800US) for it."

Mike is working on his second frame design now.
