Need Help: Something is "Slipping" on my newly built Fixed Gear
I recently converted my old 12 speed General into a fixed-gear. I did the "real" conversion with new cranks and a set of cheap track wheels with a flip-flop hub. I just road the bike for the first time yesterday and when I go to attempt a skid-stop or am standing to climb large hills something occasionally "slips." It is the weirdest feeling and I am not sure what is causing it. I am almost certain it is not my crank arm on the bottom bracket spindle. I am wondering however if the "slipping" is not caused by my rear wheel moving slightly when the axle is really being pulled hard. Funny though, you think I would notice a difference in the chain tension if this was happening, it does seem that my chain tension is any different though after the "slipping" occurs. Anyway, I don't want to die and this slipping thing makes me feel pretty unsafe.
Any thought??? Thanks for the help, I have searched the forums for some kind of answer but found nothing.
