I have been riding SS for 4 years. Fixed and free. My front chainring is a 52 tooth and the cog is 17 tooth. Its perfect for L.A.
anyway, I have ridden to san Francisco on my bike(single speed) with a ton of weight for 500 miles. I'd like to think I have good form.
Long story short. I get my younger bro a bike (nice bike) i convert it into a fixed gear. a year and a half of riding and he already has mad endurance. I can't keep up.
what tips do you guys have? am I old or worn? crappy bike?
