I'm pretty much on my 200m gear for a keirin.
It depends.
52x15 is a 93.6" gear. I've seen plenty of elites that ride the hell out of that gear as their race gear for the day.
Gearing is
relative. There are so many factors.
- Track dimensions.
- Crank length.
- Rider ability (age, fitness, strength, muscle fiber type ratio, etc...).
Real talk: Anything 88" or higher is fair game in local and regional racing.
Marty Nothstein rode a 94" in the Olympics. I'm pretty sure no one here can beat Nothstein (or his times) when he was in Olympic form
Yes, if Nothstein were in his 20's now, he'd probably race larger gears. My point is that a human can use such gears to go really fast on the track.
