    Absolutely perfect. I purchased the thru-axle to use with Hexlox on my Scott Solace. Still waiting on the Hexlox to arrive, but the axle worked perfectly.

  2. John P. (verified owner)

    Perfect fit/function on my Giant TCX advanced.

  3. Sam W. (verified owner)

    High quality axles with precise threads and clean labeling. Lightweight. Good looking. An excellent product.

    Originally bought one of the trainer specific axles for my Giant TCX. Got a message back before the product shipped that I probably didn’t need it, as my stock axle should work fine with my trainer. However, the rear axle that came with my Giant TCX cannot be securely fastened on my CycleOps Hammer due to the length of the handle on the stock thru axle. So, I was recommended this product instead and it shipped fast. As expected, it works great. The only wish I have is that the washer, a single one (6mm I believe), would instead have been two washers of 3mm each. Using just on washer would’ve made for a perfectly flush fit on my Giant TCX (although this doesn’t matter much on a trainer). Excellent customer service!

    Perfect fit on my Liv Langma. Beautifully low profile and light.

    Superb product, light and strong. Service was excellent even when I messed up my order was corrected very quickly and politely. Quick post to the UK too.
    I’m very pleased and have already recommended.

    This axle was a direct replacement for the bulky stock rear thru axle. Cleans up the look of my Giant TCX-CX. Thanks for making a high quality axle!

    Fantastic fit for my Devinci Hatchet. Roughly half the weight of the stock thru axle and way easier to install and remove! Have bought one for my trainer, as well as a set for my road bike!

  9. Brian (verified owner)

    Purchased to use with Hexlox and replace the quick release axles on my All-City Cosmic Stallion. Lightweight, well-made, and easy to install. I now have greater peace of mind when locking my bike away from home. The cleaner look is an added bonus. Very satisfied.

    I have used RAP axles for both front replacement and rear replacement of the QR15 and QR rear axles that come with the frame and forks. I’m only buying custom build bikes so each part is important to me. My latest build is a gravel bike and the ENVE fork has a 100×12 through axle that sits nice and flush to the fork. I can’t imagine leaving the rear axle as a QR with a big handle sticking out. The RAP Lightning Bolt is great upgrade and gives it a clean look. I’m going to carry a multi-tool anyway and prefer my bikes to not have handles sticking out.

    Great company and support. Fast shipping, quality product. Love it! Thanks

    Great product, the machining is exquisite and great low profile. Robert Axle helped me thru the selection process without a hitch. My application required the use of a small spacer, i was nervous about that but it worked out great and they even supplied black ones to match.

  13. Manny (verified owner)

    Contacted them with a question for correct assistance with correct axle for my Bianchi Sprint disc. Received quick reply with exact part number. Shipped immediately and received within a few days. Product is of great quality. Fit and finish is great. Bike looks so clean….

  14. Jack Preijers (verified owner)

    Company – very responsive to questions and exchanging out my axle for a different size.

    Product – these axles should be standard on all thru axle bikes. The stock version doesn’t hold up. I have a lot more confidence these won’t break mid-ride.

  15. Johan Malkoski (verified owner)

    Great customer service except for getting charged a restocking fee on the axle that I was told was needed from the photo and sizing of my existing axle I sent them. Not sure how I get charged for their sizing mistake? Regardless, it was handled and replaced and the new axle works like a charm. Looks great too.

  16. GerryD (verified owner)

    Rear is to short, front is to long. Finish is like a thread, not good on a stressed part or for precision fit. Should have sent them back.

      Gerry,
      We are sorry to hear this. Can you send us an email at info[at]robertaxleproject.com so we can get more details on why you are unhappy with the product? Thanks.

    Hated the thru axle that came with my Jamis Xenith pro, it would come loose often and never feel secure. These fit perfectly and more securely.

  18. Aaron (verified owner)

    Incredible service and support. Part is machined and made to a super high quality

    2. Add at least one key to install and remove your Hexlox system. You will receive a key which matches the Hexlox you order. Order multiple keys if you want a spare.
    3. For other all other components, check your bike for what you want to secure. Options include Hexlox’s that fit in 4mm, 5mm and 6mm bolts, so check your bike and purchase what you need!
