"Our Grand Randonneur is a true low trail geometry randonneuring frame set, which means it rides better with a front load than other touring and road bikes. Co-designed with Mike Kone of Rene Herse/Boulder Bicycles. It will fit all the gadgets a good rando bike should have. The traditional diameter tubes lend a smooth comfortable ride."
Interesting, the quality of my Soma Stanyan is very good. I'd but another Soma without qualms.
A relatively inexpensive frameset to see what all the 650B shouting is about.
