I returned to the Wheelworks in Belmont MA today to test-ride a 26x26 and 26x20 SWB. The Giro 20-TT and Strada were set up, both with the Euromesh seat, in the right frame size, so I rode 'em.
Compared with my test ride the other week on a Giro 26 in the large frame (which I barely fit on) the latest bikes were much more fun and easier to handle. I can see having more confidence on the 20" front wheel since the lower BB requires less athleticism to handle, particularly on frequent stops and starts. I also like the idea of converting Giro 20's to 26x24 to find a middle point between the styles. However, my riding is mostly on suburban roads, not urban ones so the start/stop issue doesn't bother me too much. The 26x26 would require my improving flexibility somewhat to make getting the 2nd foot onto the pedals after a stop a smoother process.
My conclusion is that I'd prefer the smaller front wheel for now but can live with the larger. I am still lurking in the classifieds and I hope my Trek bike sells ASAP so I can shop in earnest. I wish I could own one of each, the smaller front wheel for commuting and the highracer for fun rides.
