Jumping chain

[Reden]

The chain on my SS seems to jump.

Just finished the build. I used a FireEye rear sprocket and spacers, FireEye springed tensioner, half link chain and a Race Face Turbine chain ring mounted onto LX cranks.

Checked the chain line a couple of times to get it right.

Due to the limited spacers in kit I had to move the BB spacers to the left side.

While pedaling lightly the chain seems to jump.

the chain run centre on rear sprocket but seems to be running to the left of chain ring.

Any advice?

I'm almost at the point of ditching the chain and chain ring and going for a DartMoor setup.

 

Race Face chain ring is 10 speed though!

It's undoubtedly the chain line. Also, it's recommended to use a chainring designed for SS use. Is the chain itself new or old? A stiff link could make things worse.

Everything is brand new and no stiff link also. Checked that.

Did the stick test and everything ties up.

My only opinion is that it might be the chainring itself.

Where do I get SS specific chain rings in JHB or Pretoria?

Jumping chain is most definitely chain line slightly out.

 

Rush sports have the e13 chainrings.

You can also shorten the chain by a link or 2.....

my 2c. Check your chan rings are bolted in straight, take a link out and check the drop out is straight.

 

You can also swop the rear spacers around, thus moving the rear cog.

The chain is currently made to suit a 18T sprocket. 16T installed.

Will see if I can remove one link but first I'm going to replace the chain ring and get better spacers for better setup.

Definitly take a link out.

An SS specific chainring and Cog helps alot. As it has wider and higher teeth and there are no ramps.
