Mt Washington Fixed I ride a 20t chainring and a 21t cog. I spin ridiculously fast on the approach but once on the hill its just right. (1:43.57 this year)day after Ascutney)
Geared I ride a 20t chainring with a 9sp 14/25 ultagra cassette with the second cog removed so I could add a 26T. My four lowest are 21-23-25-26. No front derailer. (1:37:30 This year)
Fixed gear riders know how to spin so don't worry about spinning out.
