I'm planning on taking a trip from Boston to D.C. on a track bike over my spring break. I'm going to be riding an olmo gara pista and I've guaged that a 58/17 ratio would be good for flats, easy with some kick to it and not a lot of spin. I've also determined that 58/20 would be a good climbing gear. This now raises the question of what kinds of hubs do I need to get to do this. I know Phil Wood makes some nice ones, and that Suzue Pro Max also makes a double fixed as well as Surly (which I hope to avoid). Does anyone else make a similar hub or are these the only three?
