This may sound like a bad idea, but I wanna learn how to ride my 43-pound all-steel beach cruiser uphill in the San Diego area. I was thinking, I have a decent deal of endurance (as your typical 3-mile jogger), took out the chrome fenders and switched to a smaller [36T-32T] chainring I could change my gear ratio to better suit the climbs. The flats could very well drive me nuts as I spin out but there is only so much of it in my local topography. Bad idea? What are the other factors for me to consider?
