I wasn't too worried about what they look like. I just wanted to make them a little lighter and more portable than they are at present, and as no one could furnish a good reason to have a big rear wheel, I thought I might as well switch it/them out and see what negative difference it would make (if any). While I also thought about the convenience of having two tires and tubes the same size, I am very shortly going to buy a couple airless tires. After a couple flats so far, a python is not very "user friendly" with a flat. I'm going to get a couple from airfreetires.com, and then NO MORE FLATS! :) I'll let you know how they work when I get them installed. I finally got the movie(s) converted and made three. One with both pythons, my BHP and Marcel's. The movie links are at the top of the page. http://bikes.jkcc.com/python%20clone.htm There's no sound and the quality is reduced to reduce the file size. Fine details aren't really a requisite, IMO to tell how a python rides in the clips :) Lastly, our little track was finally cleaned up enough to put in some runs and Marcel and I did a couple 1K and 500m passes. He got a flat on his sidewall (??) on the warmup laps and so couldn't ride his. He rode mine instead. Anyway, we were hoping for a little better results but I guess 5 hours of shovelling and sweeping had more of a toll than we thought. We want to go back and use a little driveway patch to smooth out some of the expansion joints and a few other small details before the snow starts flying, but we're both pretty happy with the state and smoothness of the track so far. A few more tweaks and it'll be a prime venue. Our times are here: http://georgianbents.org/results.htm#500m, also scroll down a little for the 1K times. We'll be back to see if we can knock the times down and raise the speeds, hopefully this year too as it's been unusually warm. > > I'm > > still not sure why anyone would have a big rear wheel if they don't have > > to. > > From having two 26" wheels and going to a 26/20 and a 26/16 combination, > > if > > there's any disadvantage to a small rear wheel I have no idea what they > > would be.
