Decathlon Rockrider EST-900 Thru Axle size

[Derelict Detective]

Hi I need a thru axle to put a trailer on my bike. Does anybody know which thru axle adapter I need to get. I have no idea what the numbers mean.
I have put a photo of my thru axle and a screenshot of an adapter i found on amazon. Is this right?

Many thanks

Look at yours and compare -
Your axle has a TP (Thread/ pitch) of 15mm diameter and the thread pitch (or coarseness) is 1.5mm, and you'll need to match those so it screws into your frame.

I'm guessing your rear wheel hub will be 148mm, hence your axle has an extra 10mm to fit into the frame either side.
