It could be just two different riding positions, but I have 180's on my Bianchi Muss, 17.5 frame, that I bought used to try out a rigid bike. I hit roots/ rocks all the time when pedaling uphill over rough terrain. I also have a Bianchi Wuss, 17.5 frame, with 175's on it, which are what fit me for that bike, and I still have pedal strikes occasionally but with less frequency it seems. Could be alot of other factors but that's just my experience with the two sizes.
