    Brilliant bit of kit that fits perfectly and does the job it was designed for without any fuss. Just follow the instructions on the website to select the correct axle and place your order. Delivered to the UK in two weeks as promised and the guys at the Robert Axle Project couldn’t be more helpful. In fact it was so straightforward I ordered another axle for my Bob trailer and with a couple of quick modifications to the Bob yoke to open it up to the the width of my boost rear (see the Robert Axle Project YouTube instructions) the axle dropped in to perfection.
    Sweet as, thanks guys!

    Works a treat with my budget Nashbar trailer and my new Raleigh Willard 2. Fit and finish are excellent, took maybe 5 minutes to install.

    It´s a very good product.

    I ordered my axel and the day it came I got an email from Chris at the project and let me know they might have sent the wrong axel by mistake. I checked and indeed it was wrong one, they sent new one right away. I was extremely happy with their service and their outreach to me even before I opened my package. Top service let me say!
    The new axel arrived very quick and worked great. My daughter loves going on rides and now she can go with me with my new BMC. Quality is great and everything was perfect!

    Quick shipping easy installation perfect fit and function what more could anyone want.

    Great product and support here.

    This is fantastic! I’m not highly mechanical at all. I read the directions and watched the YouTube video. Took no time to replace the old axle. Been riding around with the toddler in tow ever since.

  8. Andy (verified owner)

    It’s a thru-axle. It installs easily (watching the install video helps) and it does the job I need it to. Nothing fancy other than the price tag, but it’s the only way to pull our dog trailer on my new bike.

  9. Garrett M Frampton

    Works great for my 2018 Raleigh Redux iE electric bike. Took 2 minutes to install. On day #1 I forgot to tighten the nylon washer and lost it. Robert Axle sent me another for free. Thanks! I did buy a T-shirt.

    Expensive but well made product. Superfast shipment. Fit my 2018 Salsa Cutthroat perfectly. Pulls the Burley Bee nicely.

  11. Braf (verified owner)

    Works great. Fast shipping. Easy website.

    Only issue is that another spacer would have been nice. Installed the threaded portion protrudes significantly out the other side. I probably could have just asked for one and they’d have sent it, so it really isn’t their bad.

  12. Robert E Martinez (verified owner)

    Great product. Easy to follow instructions to order the right axel. Easy to install. Now when my wife and I ride the dog goes with us. We’re a happy family. And I will be order an axel for my wife’s bike. She wants to be able to tow our Charlie as well.
    Had a few questions when I placed my order. Questions were answered ASAP.
    Excellent customer service!!

  14. Brandon (verified owner)

    Man, I wish I found this sooner… thanks so much for the excellent service and product. Axle works perfect for my Thule chariot on my Haanjo. Keep it up!

  15. DW (verified owner)

    This product is great and is built solid! I wish I had found it years ago and I’m almost embarrassed at my own attempts to figure out how to make something to pull my kid’s trailer that worked, was safe and wouldn’t damage the bike or trailer hitch.

    I’m riding a 2016 Giant Reign and now I can pull my kid and ride my preferred bike instead of my old hardtail from back in the day. I ended up using the online axle finder, not the paper one and everything fit perfect. I’m a happy customer and have already been telling others about this great product : )

  16. Yannick Labrecque (verified owner)

    This product is exactly WHAT I needed for my Octane GRIDD 2020. The shipping was fast and customer service helped me find the right part.

    Excellent company, excellent products.

    Am riding a Rocky Mountain 2017 950 RSL with a SUNringle SRC 12x148mm thru axle.

    The axle fits perfectly well and is super solid. Rode first time today with the kid carrier and works awesome. Am really happy with the product

  18. Richard Mannino (verified owner)

    This is a well made product. I used my existing Burley hitch for the old style axles and tightened the nyloc nut just snug. The hitch is still adjustable in rotation but does not rattle. Thank you for providing this product for a secure, simple trailer mount.

  19. Joshua Axelrod (verified owner)

    Super simple to install and glad I finally ordered directly from RobertAxle, as they were able to confirm which axle fits my bike. And very happy to be hauling two kiddos behind my thru-axle bike finally.

  20. Kjetil Reve (verified owner)

    Probably the best customer service ever!!

  21. Davide (verified owner)

    Perfect product, service and delivery even to Italy.

  22. Nick (verified owner)

    Doing tons of rides towing the trailer on the ‘cross bike. loving the axel so far.

  23. Devon Schmidt (verified owner)

    Fantastic product, couldn’t be happier with the fit and finish. It also showed up a week before the estimated delivery so we were able to get out riding sooner than we hoped for. I would suggest this axle to anyone who is looking for a durable axle for their mountain bike that still wants to go on family bike rides when they’re not shredding the trails.
