I just purchased a langster today from the local lbs and they took it in back i assumed to check to make sure everything was tight. and put it on the fixed side for me.
i get home I recheck the allen keys. and i realize that seatpost doesnt have assembly lube on it. I figure I will get some tomorrow and recheck everything that gets it.
either way I am excited about having bike so i take it for a ride. I get it somewhat adjusted. the second turn from my house is a downhill I back pedal to stop with one foot clipped in to track stand at the bottom, and my cog and chain came off. and I suddenly have no back pressure so I slip off.
I get up rotafix the cog but I cant do much about the lock ring and I put it on the freewheel side and go home
