It looks like the seat tube angle has been relaxed quite a bit to compensate for the pushed-foward pivot joint/shorter top tube.
Nice track drops.
yep, there are 3 wheel sizes: 406, 451 and 501 (wheelchair 22inch and bmx 24inch). Peter tried out 501's for track racing since minimum wheel dia allowed is 22 inch. Here is what he said - <sic> "Just be sure to be clear- the 501s were a nobel experiment, and it's not practical to replicate for production, given parts availability. The new frame is intended for use with 406 and 451 rims."
I think there is limited tire choice for 501 (like 2 or 3 tires, from wheelchair stores).
I thought the seattube looked funky, but it has grown on me. The 2 tubes that connect hinge to bottom bracket appear veritcal almost.
