Antonio's 54.5cm Roaduno. 74cm saddle height

Antonio rides this bike far more than his other ones, even on rides were having a couple more gears would make things a lot easier. 

I think there's a gallery somewhere on the website of this bike right after he put it together, but it looks way better now that it's all beat up and stickered. 

He uses a 42x19, which is just low enough to grunt up major hills, but not so low that you spin out instantly on slight downhills. It's a good choice for the Bay Area.

It's not the worst tire name, but it's still weird. With this tire, Antonio enjoys Pure unadulterated Contact. I also think "Urban Contact", another Conti tire, is pretty good, as in, "I'll check in with my Urban Contact and see what's going down".

Here's Antonio and Roman, discussing the merits and shortcomings of different single speed gears.

good bike! We're out of 54.5s, but there are still some 58s, 61s, and 64s.
