yeah, if i can recall off the top of my head, its not really that pursuit-ish. a think where the head tube meets the top tube on a 54cm affinity is around the same height as most other 54cm track frames that have level top tubes. basically, your stem is gonna be in the same position as any other frame, you just don't have to raise your seatpost up as high. its a longer seat tube.

but i'm not 100% on that. if you can email the guys over there, i'm certain they'd be pretty enthusiastic to talk to you about it.
