However, going down 15mm when out of the saddle will be a pretty big disadvantage due to the decrease in leverage. You'll probably fatigue a lot faster when climbing out of the saddle or sprinting. WebFWIW, I regularly go back and forth between 170mm and a 175mm without even thinking about it. The 175 is on more of a play bike than a miles bike, sits on a higher bottom bracket, sees more spurts while standing. The other two bikes (road and tour) get more cadence, have a lower center of gravity, get ridden for hours and hours straight. st. clair shores mi
