Hub Bolt Size to Attach Thule Bike Trailer??
« on: April 05, 2021, 10:30:55 PM »
Hello, fellow WagonHeads!

I have a 2019 RadWagon and would like to attach my Thule Chariot 2 jogging stroller.  I have ordered a replacement bike adaptor ezHitch cup (https://www.thule.com/en-ca/accessories/axle-mounted-hitch-cup---main-body-_-1662756) for the stroller bike attachment arm to lock into (ball and cup joint). 

However, without a hub adaptor, I do not believe the ezHitch cup will provide enough clearance from the bike frame for the stroller bike attachment arm to connect.

Unfortunately, I do not know the hub bolt thread diameter or thread count to make sure I get a correctly sized hub adaptor.  I came across the adaptors linked below which I believe will do the trick.  I just don't know what size to get - or if there is a better option.

Any assistance would be greatly appreciated.  Thanks so much!

Cheers
Dave
