So what is the best way of mounting exposure bar lights to Jones bars?

Ideally I think I'd want to mount on the outer sweep but that is too narrow I think.

Mount on the back bar and the front casts a shadow.

Hang it upside down on the back bar then bar bags are in the way.

Front loop is fine. Exposure mounts with the shims

This.
It is however possible to mount a Revo (and other Exposure depending on size) to your fork crown (where this is possible) using a SON/ B&M/Supernova mount and an Exposure action camera adapter.
Your light can then sit under your bar roll on bikes with a tall enough head tube.

Dounle check to be sure, but i think its the 12 x 22.2 for the front loop. Just need to add something to stop it slipping..

A wrap of old inner tube for the northerners among us.

As Taylor says, old inner tube works just fine.

Thx all.
Now where did I put those shims.

I'll go digging.

I find inner tube too floppy for this use case.

If you can’t find shims try inner tube pulled really tight with a big wrap of half or third width duct tape

Self-amalgamating rubber tape is what you want.

I don't use Jones bars (I tried them and don't get on with them) but I do have Redshift Kitchen Sink bars on my gravel bike which throw up the same issue. I initially tried using various tape and diy packing options but found that the light would tend to move on bumpy terrain so I googled 22.2mm-31.8mm bar spacers and managed to get some dedicated widgets. These have worked well and the droopy light issue hasn't returned so I'd deem them a success. A quick search reveals these which look similar to the ones that I got. https://www.amazon.co.uk/dp/B077KS2RTZ/ ... WH7GWC4MQZ

I use the exposure mount that clips on with zip ties to the front loop. Works well.
