What is the width of the skewer itself?

Hi, The Width of the Skewer is 0.74".

Will this work with a sunlite F2 trainer?

I have a F@ Mag trainer and that is very similar and it works fine.

Can I use it on nut bolted attached wheel?

If you can run in through your wheel hub I think it will work

Can I keep this on bike for when riding outdoors or do i need to switch back to the original skewer beforehand?

Yes, the skewer can remain on your bicycle at all times, whether you're using a bike trainer or riding outdoors. No need to revert to the original skewer.

Not compatible with Kinetic trainer

I got this for a kinetic and it wasn't right. Kinetic requires their own brand. The skewer itself seemed nice.

It gets the job done

I bought this for a cheap indoor trainer, and it works as advertised. The metal is not as high-quality as I would expect, but it hasn't broken yet, so I have no complaints. It does the deed.
