I took a quick tally from a riders data file that I have and found a few nifty details.
It looks like there are 4 singlespeeders out there.
About 9 fully rigid bikes started.
Seven 26ers.
The rest are on 29ers with sus of some type...35+, approx.
About 20 bikes are custom or extra-small shop.
8 Fishers, 4 Giants.
(4 riders from the UK. 1 each from France, Germany and Canada.)
(Some riders didn't report very clearly and I was counting quickly...)
No fixie this year.
(Deanna Adams's cheapy homebrew fixie roadbike conversion from last year is my personal highwater mark for freakout bike culture.)
