I got my road/touring bike today and put 10 miles on it. The 175mm crank with the gearing and how the bike rides fits really well. The combination gives me more available torque, but seems to be a bit of a loss in the cadence department - 61 before to 58 on my ride now, though I picked up several mph. So with all the factors together I am not sure I can really tell a difference strictly due to the crank size change, but it appears to be a non-issue. All together it is a pretty big improvement over what I was riding so I'm happy.
