top-level sprinters might hit 60mph.
I still contend that the current road sprocket ranges are for posers, or very serious racers.
Freewheels used to commonly be 14-28. 14-23 was a 'racing' freewheel for fast club riders.
13-25 is a range suited for racing, but not for general riding.
Now, it would be fine if the mtb world offered a 14-28, but it doesn't. 11-30, 12-32, sure.
The old 14-28 is a range suited to general cycling that just doesn't exist anymore.
