Keep in mind that the Some Rush is measured from the center of the bottom bracket to the top of the seat post collar, so keep in consideration that you might want to go the next size up. I have cane creak 1 inch threadless headset and a dimension stem, comes with a shim to fit the 1 inch fork. You can definatly for cheaper than the way I went. Stick to threadless since the soma fork comes unthreaded and its easier to set up that way.
