Yeah, I need the real estate up high. There are a few hills I bomb down. On one bike, I have a 52 - 11 on a 175mm crank for 127 gear inches. The other one has a 52 - 14, 175 mm cranks for 97 gear inches. If I had about 110 gear inches on the bike with the freewheel, I would be OK. Anything above 120 gear inches covers the riding I do.
