David's sweet rigid 29'er sold by our man in Germany: Ken Bloomer of IFbikes.de.
(Ken has some cool stuff on his blog that is also worth checking out.)
This bike just shipped out the other day. It's amazing to see how fast it came to life.
David put a cool contraption up front to keep the chain on the single ring.
He is running a 5 speed rear "cassette" on a Chris King singlespeed hub. the shifting is provided by a short cage Dura Ace rear derailleur, pretty neat and well thought out.
He seems pretty psyched, to say the least.
