What do you think...too tight? I have set it up with this clearance with 52:15, which is the largest chain ring/cog size I would use for all configurations. I can gear up to 100 inches by adding a 14t cog and everything in between with smaller chain rings, with plenty of clearance on my chain stay. But despite the aerodynamics of the tight clearance, are there dangers in it being that tight? I might be taken out by a small pebble. ;-)
