I'm considering going to a taller 28" tire which brought up a question. With my current setup (4:10 gear and 26.5" tires) I cross the finish line in 4th gear @ 6100 rpm (100 rpm short of redline). What would be the ideal rpm for me to cross the finish line at? Since taller tires will reduce the rpm somewhat, will this help or hurt me? Thanks in advance for your input.
