I took a picture of the broken, but i can't find the exact same one. I found another one on the Trek site that has pretty similar parameters. One bike shop says it's fine, but the other says i need the exact same one as the broken one
Original part number: 12×122,5 M12-1.75×22-W565811 (the broken)
The one i found on Trek site: 12×122,5 M12-1.75×10,5-W584102
On the official Trek site I could not find a part matching the original front thru axle

I got a few of AliExpress for my domane al2. Can’t post Ali links here. Search, bicycle through axel skewer.

Assuming [this ](https://www.trekbikes.com/us/en_US/bikes/road-bikes/performance-road-bikes/domane/domane-al/domane-al-2-gen-3/p/33083/)is your bike. going down to the Service section of the page suggests either will work.

The original (linked [here](https://www.trekbikes.com/p/W565811/)) should still be available though that may depend on your region.
W565811 or W584102 both will work and in-stock
