I ended up not putting a 14 on the front after all - The shop mistakenly ordered a 15.. So I put the 48 that I had back on the rear. I would have been at 14/51 but am now at 13/48 - the two are pretty close to each other. The 15/48 might be too tall. And I need a new chain to run the 15/51.
The gearing at 55 is noticeably taller now, but not great- I do wish it was a little taller. For now, it needs to stay at this since I leave Thursday and dont have time to mess with it more. I'll revisit after the trip.
