Jumpy Chain
Single Speed, chain jumps off rear gear, other than the obvious about chain being loose, any thoughts on adjusting? Its a 54 - 16 ratio. - Ta.

54X16 seems a bit of a jump ... may need more chain wrap on the rear cog. Have you considered perhaps dropping down up front a bit? Seems like a huge gear anyway. 1/8th or 3/32 DT?

I didn't read the ridiculously high ratio before, that could definitely be the problem.

Im using 52 x16 and with my chainline out it jumped. So it can be that factor.
