So ive been getting some serious sores whilst riding my fixed gear. I am getting them in cycling shorts, and I have never had problem with my multispeed bike. I assumed that the issue was the seat (nasty motobecane stock seat), so i swapped my seat from the road bike and got a new seat for the roadie. No luck! Im thinking the issue may just be I need to get used to my increased leg speed on the fixed gear. Has anyone else had problems?
