One of the goals of the rSogn (reissued Sogn) is to reduce frameset weight. The rSogn would be available in three sizes: Small, Medium, and Large. These sizes would feature heat-treated Taiwanese tubing.
For the Small, the top and down tubes would be 7/4/7. The Medium would feature the same top tube, with a 8/5/8 down tube. Both the top and down tubes would be 8/5/8 for the Large.
All top and down tubes would be 28.6 and 31.8 in diameter, respectively. Other parts of the frame and fork would be specified accordingly, with the stated goal of making the frame and fork as light as possible for a $600 frameset.
As we all can imagine, this topic could potentially determine the entire design direction of the rSogn. The requests for reissue received so far have been pretty much even between 650b and 700c.
As far as design and application are concerned, 650b is the ultimate wheel size. At the same time, 700c is readily available when it comes to small-block cyclocross tires, for example. Personally, I enjoy the benefits of the 650b size; however, I am still patiently awaiting a small-block 38c in this size.
To this end, I am fine with either 650b or 700c for the rSogn, and leave this up for discussion.
