Well, it's a good "proof of concept" bike for me, but there's a lot that really isn't so great. The curved/twin top tube deal, for example, is eye-catching but just doesn't work as well as a traditional one. And the overall geometry is a bit weird too - in order to get a reasonable seat tube fit I would have had to go with a TT something like three cm. too long, so I ended up with the little tiny frame and a mile of headset spacers.
But it does all work, more-or-less, and it is a lot of fun. I think I'm going to go custom to solve all the niggles and then have a bike I like a lot.
