I’ve been really enjoying conquering hills lately on my fixed-gear commuter, and I’ve started entertaining an idea of building a second lightweight fixed-gear bike specifically for climbing big hills. Gearing aside, how should I size the frame for this? My current bike’s stated size is 56cm (redline 9-2-5 with drops and 10cm stem) and it fits well for riding in the drop or on hoods. I like to be out of the saddle a lot when climbing, and I was thinking perhaps a shorter top tube (53-54cm range) and time-trial bars instead of drops? Am I on the right track? Would a smaller frame be better for climbing out of the saddle? Thanks!
