Whether you are towing your kids, your dog, or a cooler full of refreshments, the Robert Axle Project has the thru axle solution. The Kid Trailer Thru Axles allow you to attach a “hitch mount” style trailer, to any thru-axle equipped bike.

Great customer support from SJS and fast email responses. Shipping was excellent.

Have only tried to mount the axle on my bike and it fitted perfect. Haven’t rode it yet due to lots of snow. Feels like good quality.

Cannondale Treadwell EQ
03 Sep 2019
Hi, have a Cannondale Treadwell EQ, rear axle is 12x169 with a 1mm thread (open to correction) & looking to pull a Burley kid trailer. Would this be the correct axle to buy? Many thanks!
This is going to be the closest available to 169mm so yes, this would be the best option.

Thanks - 03/09/19
Can I use this with a Lapierre Zesty 527 2014
21 May 2019
Hi I have a Lapierre Zesty 527 2014 and think that the rear axle is a 12x142mm. Looking at pulling a Thule trailer so was wondering which axle to buy? Many Thanks
Hi there,

Unfortunately, as we do not stock your bike or the trailer in question, we would have no idea as to what would be suitable I'm afraid.

Cube Stereo e-bike

I have a cube Stereo e-bike. The axle description when I remove my axle is
1712 QR50BEX -12-167-P1.0-16I
I am looking to fit my dog trailer to my bike, can you please advise me which axle I need. Many thanks
Hi there,

Yes, this in the 167mm seems like it would work but you can use the fitment guide to establish the exact axle measurements;
