Will this Thru-axle adapter fit my Surly Disc trucker ok?
 

Just want to be certain, as I am terrible with mechanics. Was gifted a Saris Fluid 2 indoor trainer, but it came with a standard quick release axle to use with the stand.

My Surly has a rear thru-axle. The adapter options on the Saris site to purchase is either:

And the specs for my Surly are:

So based on this, I would need the last option of the three to match the thread pitch of 1.5, and the 148 can work with the 142?

Thanks for any help!

Looks like you want 9733T

142x12 1.5 thread pitch

It looks like the adapter comes with a set of washers/spacers that allow you to adapt to the correct width so long as your within their parameters. The only thing that is important beyond that is that you match the correct thread pitch.

Also looks like that is the only option. If the thread pitch is not the same, it won't thread into your bike (at least in a way that will not destroy the frame).
