Ridley Damocles ISP Limited Edition
We received a small allocation of Ridley Damocles ISP Limited Edition framesets that will ultimately find their way into the hands of a few lucky customers. These bikes have integrated seat masts, reducing weight, bringing that lovely carbon right up close to the rider, and making the bike accelerate like nobody's business. Custom paint celebrates the Italian National Champ's victory on a Ridley.

Considering A New Yeti?

WE ARE THE YETI EXPERTS in San Francisco. We stock our own fleet of demo bikes for you to ride before you buy. We also work closely with Yeti's Factory Demo folks in the area. We're happy to ship worldwide, too. Call or e-mail us with questions or requests. Check out all of Yeti's bikes here.

Updates to the 575 for 2011 include a beefed up, 1 1/8 to 1 1/2 head tube - the Anniversary Edition gets a custom color King headset too.

A new swingarm similar to the ASR 7, with burlier chainstays and a bomber main pivot / seattube connection

And of course, a 142 x 12 thru axle in the rear to stiffen things up

Of course, that custom colored King headset wouldn't be complete without a bb to match.
