Been test riding relaxed geo road bikes. I get stange looks when I ask about Cyclocross bikes... None in stock. So I've ridden Cannondale Synapse,Trek 2.3, ect. I'm concerned about My 215 lbs on 23mm tires. I asked a salesman that was a heavier, old guy like myself about this and he said "When you wear these out go to 25mm tires." I said "What about 28's?" He replied "There isn't any advantage for them over 25's."
Speed is secondary to comfort for me. The roads I ride are rough textured oil and chip.Would the lower pressure of wider tires benefit me?
