Rivendell makes a variety of nice frames. Everything from full custom bikes made by Curt Goodrich, Japanese built frames, and a less expensive fully-lugged Taiwanese frame called the Bleriot. The Bleriot is identical in geometry to the Japanese made Saluki. Rivendell's custom and Japanese made frames are in very short supply, and to get your hands on one contact Rivendell. The Bleriot frameset is more widely available and we sell them. We have one built up in shop (a 57cm) if you'd like to try it out. It's an extremely versatile bike. We've done everything on it from riding club rides with guys on $4K carbon bikes, commuting around town, and--with a change of tires--riding a 56 miles gravel road loop near the Red River. The list of bikes that you can do all that with is pretty short. Framesets are $750, which includes a headset. You can build them up any way you like.

Check out Rivendell's Bleriot Page for more details. They also have a nice pdf link which includes geometry for the bike.
