But if you took a 925 and put a bigger ring and smaller cog on it, you would be faster on it than you would be on a geared road bike with the same geometry.
I've tested my theory. My best average speeds on my perfectly flat commute with no wind have been on my fixed gear. Also, one summer I did several 10 mile out and back time trials. My personal best was the time I did the course on my fixed gear.
