    Works perfectly. I had some issues with my stock QR thru-axles, so the upgrade to these axles has worked out great. Lightweight, low profile, exceptionally well-made. Highly recommended.

  2. Alan Floyd (verified owner)

    A precision high quality thru axle that is a direct replacement for the front stock axle on my Giant TCX-CX.

  3. Adam Clement (verified owner)

    First set worked flawlessly and quality of construction is reassuring. Just bought a second set for another bike and imagine will get more. Just need to buy another bike 😉

  4. ronell mallari (verified owner)

  5. Pat B (verified owner)

    Awesome quality, very light. Allows for repeatable torque every time compared to the clamp style axles. Highly recommend.

  6. Josef I (verified owner)

    Love these axles! Lightweight and Uber high quality axles that look great too. Plan on buying another pair for my Cervelo R5 disk bike.

  7. Chevil (verified owner)

    I was having issues with rotor scraping and frame flex but that was solved with RAP thu axles. So stoked to have my bike finally rides the way it should.
    Thank You RAP.

  8. Peter (verified owner)

    Love them! Thanks!

  9. Gary (verified owner)

    Fantastic company with great support. I bought a front and back axle for my 2020 Giant Defy. Fit perfectly. Love em! Thanks

  10. Martin Taylor

    Maybe I’m imagining it because I’m trying to justify having spent over $40 on a bolt, and maybe the issue will come back, but at this moment this current fixed issues I didn’t think had anything to do with my wheel attachment. Basically when I got out of the saddle the front end of my bike creaked like an old wooden staircase, I figured it was because it was a flexy endurance bike and not hi-mod carbon. I bought this because I thought a poor axle/fork interface was negatively impacting my brake rotor alignment. I installed this, my assumption was correct-ish, the rotor/caliper alignment was about 50% better, but then I went for a ride and I got my fat almost-clydesdale butt out of the saddle and sprinted and I heard…nothing. My bike was quiet when I was sprinting for the first time ever. Maybe it’ll come back, probably, but right now I’m attributing it to these axles since that’s all I changed. Also, I’m a nerd so I love anything I can use a torque wrench on. (which cost a bit more than this axle, hehe.)

  11. tony Sells (verified owner)

    Great product, the machining is exquisite and great low profile. Robert Axle helped me thru the selection process without a hitch.

  12. Aaron (verified owner)

    Fantastic service and top quality machining! Will definitely buy again.

  13. Jose (verified owner)

    Amazing product! And even better customer service.
    I placed an order on a Saturday and received the axles on Wednesday (shipped to Canada) despite the fact one of the axles was out of stock.
    I’ll definitely buy more products from them when needed.

  14. Marcus Chard (verified owner)

    Nice product, good quality, put them on mine and my sons CX bikes.

  15. Joe Fahey (verified owner)

    Perfect match for my 2020 Lynskey GR300 with standard carbon fork. Looks fantastic, and more importantly, it works flawlessly. Shipping was fast and easy.

  16. KrikkeSteen (verified owner)

    Dankzij de goede uitleg de juiste keuze van produkt gemaakt.
    Made the right choice of product thanks to the good explanation.

  17. Bill Dister (verified owner)

    High quality, exactly what I needed and shipped very quickly.

  18. Dean Kathron (verified owner)

    Fantastic fit and finish. Saved 28g on front axle alone over stock thru axles. Weight saving, aero saving and look amazing.

  19. Frank watters (verified owner)

    Very well made and much lighter than the stock ones

  20. Mark Smith (verified owner)

    Fast and above better than the standard Lynskey QR Style axles that came on my PRO-GR

  21. Allan Nicholson (verified owner)

    Purchased a set to replace my stock 2021 Bianchi Infinito CV thru axel with the integrated lever that had developed an annoying rattle after 8 months. Worked like a charm – bike is whisper quiet again on the bumper downhills. Only point to raise is that I feel the rear one could be 3-4 mm longer.

  22. Jamie (verified owner)

    Not only a superb product, but backed with superb service. (1) I was ordering from overseas, and after taking the order they wrote back to offer me a cheaper way to do it via another country (I still stuck with the US office). (2) I accidentally received a slightly different size from the one I ordered, but the super clear instructions made that obvious right away before I assembled, and so when I asked them about it, they shipped the correct one immediately without question or cost. I was just so impressed and thankful.
    Further, it fits my bike precisely. The original thru-axle that came with my bike relied on hand tightening, which is convenient to be sure, but the fact is I essentially never take the thru-axle out, but now I can use my torque wrench to dial in the axle without worrying I’m over tightening and ruining the thread in my frame (something I’ve done before). In the event I’d take the axle out on the road, I’d have my hex key with me anyway. The only issue I can think of is when I’m tossing the bike on the race stand, since it requires me to unscrew the front wheel, and that’s more of an issue than the hand tightening method, but mildly more involved at worst.

  23. Michael R. (verified owner)

    Great axles. Wonderful support team. Ingenious drop-down menu.
    Highly recommended.

  24. David Collazo (verified owner)

    Lost over 80 grams by replacing my stock axles. Less drag with the absence of levers. Axles are smooth and machined beautifully. Top notch products and service!

  25. Pete Freeman (verified owner)

    The Mavic speed release is a pain to pull out so swapping my 700c and 650b wheelsets on my Look 765 was a pain. Problem solved.

  26. Reinaldo Santiago (verified owner)

    Excellent axles and they look great on my bike. Perfect measuring system with printable scales to get the perfect match.

  27. Kellin Stein (verified owner)

    Lightning! Lightning! Lightning! This TA is a definite, lightweight upgrade for my 2019 Bombtrack Hook EXT-C and fits perfectly without any fitment issues. Absolutely recommend this TA to others, especially if you live in Bend or Oregon – what a better way to support a local company!

  28. Joe Drumsta (verified owner)

    I purchased a Lynskey GR300 gravel bike and the front and rear thru axles/quick releases that came stock with the HED Emporium gravel wheels were just poorly designed IMO. An absolute nightmare to work. Nothing “quick” about them. I found The Robert Axle Project on youtube when another lynskey owner had the same issue. I purchased the front and rear replacement axles for my wheelset and I am extremely pleased with the quality and simplicity of these axles. I don’t care about the need for an allen key since I ride a gravel bike and carry a multi tool anyway. These are perfection and they look really cool! Thank You!

  29. George D Barry (verified owner)

    My front wheel axle “fell out” while driving to a location for a weekly ride. Thank goodness I bungee strap my wheel to keep it from spinning. Three bike shops could not locate an OEM replacement. Found Robert Axle Project and had my replacement in 3-days. Perfect fit. Would recommend to everyone.

  30. Michael Kellman (verified owner)

    Works perfectly, bomb proof, sexy as hell!

  31. Justin Tonel

    I’ve ridden my stock axles for less than a year and they’ve not lasted until I bought these. I love my Lynskey Pro GR more with your product. Thanks!

  32. Art

    Excellent of course. Dims, weight, finish all as advertised. Install was easy with perfect fit.

    Go Team Bob!

  33. Ben

    works perfectly with my Lynskey r500. Thanks you.

  34. RL

    Very light and über strong. Works fantastic on my Lynskey GR300.

  35. Jeff N

    Worked perfectly and paired beautifully with my 6mm Hexlox. No more brining the heavy cable loop for my front wheel while commuting or locking up my bike at the gym etc. Would 100% recommend to anyone on the fence about buying an axle from RAP.

  36. Mark Schenkel (verified owner)

    I bought a pair of RAP axles to replace the stock QR thru axles on my new Lynskey PRO GR and couldn’t be happier. The stock thru axles had different mechanisms, front and rear, and we’re very difficult to get properly adjusted. Consequently, I was always dealing with creaking and disc brake rub. Not anymore! Thank you, Robert Axle Project!

  37. D. Victor (verified owner)

    I too purchased a Lynskey GR300 and agree that the supplied Lynskey OEM QR axels are maddening to use. I love the frame but these had to go. I already carry a multi tool when I ride so the need for a 6mm hex to remove and reinstall the axel is a non issue. Significant weight savings for those weight weenies out there. Perfect fit and shipped quick. Get some.

  38. Ron Connolly (verified owner)

    Like others, I replaced the axles on 4 of my Lynskeys. The design allows for more precise disc brake alignment than the stock lever type. Highly recommend.

  39. Pete (verified owner)

    Like so many here, I bought RAP axles to replace the garbage stock QR style thru axles that came on my Lynskey GR300. Bonus: they cleared up what I though was a creaking bottom bracket.

  40. Eric (verified owner)

    Perfect fit. No more massive “QR” lever hanging off the side of the fork. Thank you!

  41. Kris K (verified owner)

    Perfect replacement for the stock QR thru-axle on my Lynskey R300 fork. Very light and stiff. Completely satisfied.

  42. David Stanley (verified owner)

    Fantastic upgrade for my 2021 Lynskey GR300. They are so good that Lynskey iss now specing them on their bikes.

    It’s kind of hard to believe a thru axel could make much of a change in the ride. But, the difference is tangible. The bike just feels more solid, more connected. It corners better and inspires confidence.

  43. Terry Jackson (verified owner)

    So much better than the stock Lynskeys. Worth noting my last Lynskey came with RAP as stock units. So I ordered them for my other 2 Lynskeys. Love them!!

  44. Keith (verified owner)

    Great customer service. Quality is top notch. Looks great on the bike as well!
