    Hi, I recently ordered a pair of your Lightning Bolt-On Axles for my Specialized Diverge and was very pleased at how soon they arrived at my delivery address in the UK. The axles are now on the bike and are a huge visual improvement on the nasty looking stock axles. With a small amount of copper assembly grease they torqued straight up to 12 Nm without any binding.
    Great product and a fantastically prompt service, thanks to everyone involved. USPS must get a mention here too.
    Kind Regards – John

    Absolutely perfect fit for my new my Moots Routt RSL. Super high finish quality with an understated appearance. What is not to love about that! I now recommend these to all my friends and will order more for my other bikes. Nice work.

  3. Joe T (verified owner)

    I recently replaced my axle on my DB Haanjo EXP and was very pleased with the results. Perfectly tight fit and easy to install. I would definitely recommend this and your other products to my friends and family.

    I can confirm the LIGHTNING BOLT-ON AXLE – FRONT 12 MM X 125 MM X 1.5 THREAD works with Dedacciai F-56DB Gravel Fork.

    Threads are a nice tight fit, very well made. Definitely will purchase again.
    Thanks!!!

    I ordered a set of Lightning Bolt-On Axles for my Cervelo C3 to replace the poor quality ones that came with the bike.

    Perfectly fits my Diamondback Century 5, looks very clean and easy to use.

  7. Adam Clement

    Bought two sets of these for two bikes to make wheel removal a little harder to lower chance of wheel theft when doing lock ups for coffee/beer stops etc. Was surprised how much LIGHTER THAN STOCK these are – really nice bonus! Quality and finish are top notch and I am happy to recommend these to my fellow riders.

  8. Harris (verified owner)

    Ordered this, with a couple other axles for my Devinci Hatchet Carbon to replace the stock axles, which were a little clunky. The front axle fit super clean, and with the measuring advice was a perfect, especially given that the bike has a closed end on the right side of the fork. That, and it’s less than half the weight of the stock axles. Great product and I recommend to everyone!

  9. David (verified owner)

    I purchased a front axle to get rid of the ugly Mavic axle and I LOVE this axle. The shipping was super fast, it’s MADE IN AMERICA, and they look awesome on the bike. Great products and I recommended to a friend who has purchased 2 already.

  10. Tom (verified owner)

    They’re wonderful! They’re half the wait of my Cervelo C3 axles. Thanks so much!

  11. Sam (verified owner)

    Ordered for my 2017 DB HAANJO. Shimano thruaxle was noisy as hell ! really annoying. Installed the lighting bolts, love em’ , simple, expertly engineered and machined piece. Cleans up the appearance, totally quiet and bombproof. I’ll be ordering a trainer specific thru axle this fall.

  12. Jim Ratliff (verified owner)

    In addition to selling top quality product, Robert Axle’s website was the only source I child find that put together all of the various combinations for thru axles.
    5 stars for product quality, another 5 fur website completeness.

    The Lightning Bolt really made my day! Only a week after I ordered , it came in the mail (in Canada). I installed it right away on my 2019 Synapse and went for a 3 hour ride. Excellent product!

  14. Cindy Fleming (verified owner)

    My Lightning Bolt-On Axles fit perfectly, installed easily, and look great! I bought a second set for my husband.

    Hi, recently ordered a pair of Lightning Bolt-On Axles for my Cannondale Synapse. Very quick delivery to the UK and got lucky through customs with no additional charges.
    Quick application of grease and the axles fitted in a couple of minutes. Look far better than the stock axles.
    Highly recommended and great service from the staff at Robert Axle Project.

  16. Marc St-Jean (verified owner)

    Perfect fit and nice and light.

  17. Chris Chester (verified owner)

    My original stock front axle got left on the toolbox of my truck. I did find it but it had been run over. Had to chase the threads, but decided to order a new one. I had already purchased a rear axle to go on my Wahoo trainer so I knew what to expect. You can’t go wrong with their axles. Quality!

  18. Fabian (verified owner)

    As advertised: Light, low profile, more secure, great quality. The team at RAP guided me to the right axles for my Lynskey Sportive and they look great.

  19. Petro (verified owner)

    Ordered front axle in 125mm M12x1.5 size, fitted perfectly to my 2019 CAADX fork! Light, nice-looking, quality product! Also, very fast shipping is nice! Will order Robert Axle TA bolts again:) My best recommendation!

  20. Bill R (verified owner)

    Ordered the new Lighting Bolt-On Axles for my new gravel bike to get rid of the quick release axles that came on it and the Robert Axle Project ones work perfect. It was easy to determine which axle to order using their Axle Finder web page. They also shipped them fast so I had them very quickly which was greatly appreciated. I would definitely buy from them again.

  21. Dennis (verified owner)

    Perfect fit-and well machined.

  22. Andrew E (verified owner)

    The bike matching system worked a treat . Purchased front and rear Axles- they substantially lighter than the stock set and a perfect match for the bike . Excellent customer service , product arrived within days to NZ.

  23. Aaron (verified owner)

    Perfect! Fit better than the original axle.

  24. John (verified owner)

    I replaced my OEM levered thru axles on my 2019 Synapse with this selection as recommended by the on line drop down Q&A and it fit perfectly. I could not be happier.

  25. Will (verified owner)

    Thru axle looks clean and feels light compared to the stock axle. Measurement was spot on with the axle finder for my Cannondale Topstone. More than that, the service from robertaxleproject is very good. I ordered a hexlox and they followed up with an email to make sure I meant to order just a piece of that set. After finding out I had my own hexlox products, the refunded the hexlox and sent out just the adapter to make my own products work with the thru axle. Thanks a bunch!

  26. nixon (verified owner)

    after scouring the internet for “actual” dimensions for front and rear axles- i stumbled upon ROBERT AXLE PROJECT. they had easy to find answers, product in stock, and pro delivery! thanks y’all!

  27. Lukas L

    Perfect fit for my 2019 Caadx SE. Much cleaner looking than the stock axle with lever, and lighter too!
