The crankset and seat back, plus a real front wheel

(55 days until the 2011 WHPSC) 

I originally used the old steel fork off my Motobecane 29er to hold the rear wheel in place on the mockup. The fork looks like it might be suitable for the actual fork on the streamliner, so I removed it, installing an old steel fork off my Schwinn Madison instead.  I also mocked up a seat back.

I found a used 650 tubular Zipp 870 wheel on eBay, and made a holder for it as well as the crankset. 

Then I took it for another test spin.
