question on tension
Hey guys,
I've just started commuting on my first singlespeeder/fixie (flip flop)- so this is the first time I've really belted it. At multiple times in the commute - I got some loud, concerning noises from the drive train - like the chain came off - i figure its the chain slipping - mostly at times when I was putting in the hard pedalling. I thought chain slippage was pretty impossible with how tight the chain is and how high the teeth are on both ends.
When I got to work, I checked it all out... the chain was tons looser - almost to the point that I could take the chain off without moving the wheel forward on the dropouts.
Is this a case of the wheel gradually moving forward (I couldn't tell if it had moved really) or something sinister happening with the chain?
On a side note - and blast me if you must - I have washers on the outside of the frame, inbetween the frame and the nut on the back wheel. Should these washers sit on the inside of the frame up against the cone nut?
Any advice?
