+maybe. i’m not sure what sizes they’re available in, but that seems good, or a flip flop hub. though dingle cog would be cheaper than a whole rear wheel, so worth looking into. as i remember, though, they have weird combinations–like being a 17t and 21t, that sort of thing.
edit: just googled, 17/19 is available. try sheldon brown’s gear calculator to find a chainring to give a you a gearing equivalent to what you’d be getting otherwise.

They’re available in 17/19, 17/20, n’ 17/21. I’ve got the 17/19 and like it quite a lot.
Ever ride your bike into a headwind? I have a hard time believing anyone is mashing around at 24mph all the time. Optimal cadence is 90-100RPM which is 24-27mph. I don’t really know anyone that can sustain 24mph for greater than a few minutes.[/quote]
There’s always a headwind here, I guess I’m not always in optimal rpms, especially when just riding around. I’m almost positive I’m going with the 15t, a few of my friends run 14t and have no problem. Most of the rides here are straight and pace lined and fast as fuck.[/quote]
i vouch for this.
24-27mph is definitely reasonable for miami group rides… we are flat for sure. and, the group i ride with in the morning, pulls 24 sustained for and hour to an hour and a half. and bump up to 28 for about 10 minutes of that and then low 30’s for the sprint at the end.
edit: 98% of us ride geared bikes.
i run 48 x17 or 18 if i’m training solely on the bridge (the only thing more than a bump in the rode in miami)
