I live in hilly hilly San Francisco and am new to fixed gear riding. For right now I'm only riding on the street but am aiming at getting back into shape and going down to the hellyer v-drome on Saturday mornings. I'm a heavy girl but super strong from 25 years of biking, skiing, and soccer (I'm only 29).
My set up is 46x16 (75.6 gear inches) and I'm having a real hard time stopping (skidding). I can control my speed fine but can't get enough back pressure on the pedal to skid. I want to swap out my cog for something larger, my questions is: how large should I go? Initially I was think 18, but I'm afraid that's still going to be too high. I'm afraid to go to 20 because I don't want to spinout and bounce all over the place. Again, my main objective is to be able to skid stop in hilly hilly San Francisco.
Please let me know what you think. Any advice is most welcome.
