I own a Madison that I absolutely love riding but so far I've only ridden it as a SS. I'd like to flip the hub and try riding fixed but I have one major concern...How do you stop efficiently? (Insert laughter and ridicule.) Yes, I have brakes but it seems that with the momentum of the spinning wheels that the efficiency of the brakes would be greatly diminished. Do you simply need to go a bit slower and try to anticipate better? Are you supposed to try to stop the pedals by slowing your legs and fighting the forward momentum? (That just doesn't sound too good for the knees.) I'm too old (old dog new tricks thing) to skid to a stop and I'd like to use the bike for group rides occasionally so even if I did choose to skid, it probably won't be very popular while surrounded by others.
