Your cart is empty. Are you searching for a reliable bike trailer hitch thru axle adapters? Choose ODIER and you won’t go wrong.
There are two common bicycle axles, QR skewer axle and 12mm thru axle.
(In fact, neither of them carrying the weight of the bike, it just secure the hub, the hub is the load part.)
You may able to attach a trailer hitch to your QR system without a adapter,
but if your bike use 12mm Thru Axle, you need a Thru Axle Adapter to get the bike trailer attached.
How to choose the right Thru Axle Adapter?
Step 1: Check the thread pitch and axle length.
Shaft Length
Measure your stocked axle shaft length as we pictured. If your original axle shaft length is 171mm, you
should buy the 174mm one from us, you can shorten it to 171mm with the spacers included.
Thread Pitch
1.Check if there’s thread pitch marked on the axle body.
2.If the thread pitch was not marked on the axle, you can also measure it with a mm ruler.
Here’s how to do:
Align the first thread teeth to 0, if the No.11 teeth right align to the 10mm, it’s a 1.0 thread pitch.
Align the first thread teeth to 0, if the No.8 teeth right between the 10mm and 11mm, it’s a 1.5 thread pitch.
Align the first thread teeth to 0, if the No.7 teeth right between the 10mm and 11mm, it’s a 1.75 thread pitch.
If you still unsure about your thread type please consult with your bike brand’s after service line or go to local bike shop for help. You can also sontact us for help.
How to choose the right length and thread pitch?
For example:
If measured axle shaft length is 205mm, thread pitch is 1.5, you should choose the M12 x 1.5 209mm Thru Axle adapter, you can shorten it by using sapcers
How to install?
It would be better if you spread some grease on the thread before install it.
You can adjust the shaft length for 9mm with the spacers included.
If your original axle come with a conical spacer, you must use the conical too.
There's no harm If the thread come out a bit of the driven side, you don’t need to worry about it. (Do not over tighten.)
Hold the axle in place with the wrench while tighten the hitch, so that you won’t hurt the bike frame.
(We also have QR axle flat adapters, if you need that, just search it in our store.)
NOTE; We used copper as base material in the electroplating process, so you will find copper in the hex wrench hole, it’s not rusty.
