Description

  • This Trainer Axle is designed to adapt your high quality bike to your wheel-on trainer. These are compatible with all the popular brands: 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo and more.
  • Our first priority is building a precision thru-axle. Our axles fit into your bike as well or better than the stock thru axle.
  • The axle is installed with a simple 5 mm hex/allen key. The same tool that you carry on every ride.
  • The best part? When it’s time for your race or time to head outside, simply remove your bike from the trainer, remove the drive side axle end and go. Our axle is suitable for use on or off the trainer. Indoors or out.
  • Important: Before you order, make sure your specific trainer will accommodate the width of your modern thru-axle equipped bike. Measure your trainer at the widest setting and measure the outside width of your bike frame. The trainer axle ends will extend 15 mm past your frame on each side.

Specification

Robert Axle for Trainers replaces your stock 12 mm thru axle so you can use your bike on a trainer.

  • This axle is compatible with 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo and many other wheel-on resistance trainers.
  • The true length of the axle shaft is 167 mm, but can be shortened using the included spacers to 160 or 154 mm. Please note: Thru-axle lengths do not equal hub standards. An axle has to be longer than the hub to fit in the frame. A 12×142 hub does not equal a 142 mm long axle.
  • This axle has a 1.0 mm thread pitch.
  • The axle shaft and axle ends are precision CNC machined from 7075 aluminum, and hard anodized for rugged durability.
  • No special tools required. Design allows for installation or wheel removal using your standard 5 mm hex wrench.
  • Designed, built and quality tested in the USA. Proven around the world.

    This is one solid piece of beauty. At first it did not fit on my 2016 Santa Cruz Nomad so I talked to Chris and he understood the issue and he send a replacement part right away. Customer server is second to none. Thanks, Chris.

  2. Brian Brewer (verified owner)

    Perfect solution to mate my Specialized Diverge to my Cyclops Powerbeam Pro Trainer. After my weekend road rides I setup on trainer for midweek indoor workouts. No thru axel swaps needed. Love it!!!

  3. Michael Ybaben (verified owner)

    Great quality product. I’ve been in the manufacturing sector for 20 years and I know when something is machined properly. This is a well made piece and works perfectly. Let’s me put my 2016 Scott Scale onto a trainer so I can warm up before ‘cross races. I love that i don’t need to swap anything out.
    I recommend these highly!

  4. Justine (verified owner)

    This is just what I was needing to mount my 2018 Specialized CRUX on my classic (blue older model) CompuTrainer stand.

  5. Chris McCardell (verified owner)

    Perfect fit for my 2018 Cannondale Synapse and Tacx Smart trainer. I too leave it in all the time.

  6. Emily

    Fits my 2017 Specialized Roubaix. It’s maybe 1mm shorter than the thru axle that came with the bike, but fits fine, and works with my cycleops trainer.

  7. Colin Blackman (verified owner)

    Awesome product, allows me to put my Specialized Diverge on my Kickr Snap without any axle swaps, just screw on the end cap and good to go!

  8. Javier Morales (verified owner)

    Great Product, well design and build. This product allowed for me to use my Specialized Roubaix with My Cycleops fluid 2 trainer. Very easy and safe way to use a thru axle bike with a regular quick release trainer.

  9. BC (verified owner)

    Fits my 2017 Specialized Roubaix for use with my CycleOps trainer. But that’s not what makes the Robert Axle so great. Because, you can get a through-axle adapter from your trainer manufacturer that will do the job.

    The Robert Axle can stay on, off the trainer. You can ride with it, with full confidence.

    Quality is equal to or better than OEM axle. Really thoughtful product, thoughtfully made.

  10. Mark Torres (verified owner)

    So far so good. Fits my 2017 Specialized Roubaix on Wahoo Kickr Snap. Works on bike rides as well. Its a little short(maybe 1mm) compared to the OEM thru axle.

  11. Sendjaja

    Works perfectly with my cycleops trainer. Very high quality product.

  12. Em Lowing (verified owner)

    Fit like a glove!

  13. Filip Kaurin (verified owner)

    Good quality product. Perfectly fit with my Cube Attain Pro bike. No issues during delivery. All in all satisfied with my purchase.

  14. John Tran (verified owner)

    Perfect for my Cannondale Slate and STAC Zero Halcyon trainer. No issues with ordering, shipping, nor receipt.

  15. Lou Patterson

    This was perfect for getting a Specialized Diverge onto a trainer. High quality is obvious, I’m considering buying a set to replace my existing axles.

  16. Wolfgang (verified owner)

    Clear configurator, good shop, quick support, reliable delivery, accurate invoice, fitting axle :-).

    I strongly recommend this shop with its products.

    Thanks from Austria!

  17. Kevin (verified owner)

    Recently I bought the 12mm Thru Axle for Trainer: 154 to 167mm with 1.0mm Thread, for my new bike 2018 Canyon Aeroad, with disc brakes/ DT Swiss Thru Axle, so that I can use it with my wind trainers. I ordered it online from NZ and it arrived 10 days later. Great Axle, simple to install and best of all I can leave the axle in place go for ride knowing that I can use a standard bike tool kit to remove the axle to change a flat tire. It would be pain to carry another tool to be able to remove the axle on the road OR remembering changing the axle after riding on the wind trainers (Minoura b60 and Kurt Kinetic Wind Trainer Rock n Roll). Thanks team for a great product, highly recommended

  18. Joel Armstrong (verified owner)

    I needed a through axle to put my Canyon Aero Road on a trainer, a friend suggested to me Robert Axle Project and I’m glad he did! Fast shipping, correct part and perfect fitment, exceptional build quality

  19. Mike G. Minichiello (verified owner)

    I bought this trainer axle to use on my 2019 Felt FR in conjunction with a computrainer. The fit was perfect and the quality of the axle was top notch. I am very satisfied with this purchase.

  20. Sarah (verified owner)

    Worked perfectly with my Canyon Ultimate and Cycleops M2 trainer. Love that I can just take it off my trainer and go out for a ride without needing to swap or adjust anything, and it’s sleek enough that I feel ok leaving it on my bike. Highly recommended!

  21. Herbert Woodard (verified owner)

    Top quality axles for my trainer.

  22. Kevin (verified owner)

    This is my second purchase of the 12mm Thru Axle for Trainer, for my Canyon Aeroad. I took my bike to a bike store for a bike fit in Auckland NZ, the technician doing the bike fit thought it was the best axle he has seen it is solid, simple and hassle free to use and install.
    Thanks again team

  23. Iss

    Perfect for Canyon Ultimate, did not fit Canyon Speedmaster.

  24. Roberto Quinones (verified owner)

    Beautifully machined and it fit perfectly. These guys make great products.

  25. Kyle F. (verified owner)

    The axle finder helped me find the axle that I needed for my BMC. Once I received it, the instructions for installation were clear and the end result was a perfect product for me to fit the BMC to a trainer.

    I highly recommend this product.

  26. Mike Marlow (verified owner)

    Quality product! The Thru Axle Finder feature really helped me locate the correct part. Fits my 2017 Specialized Roubaix Expert great on the Blacburn Fluid Trainer.

  27. Gabe (verified owner)

    Well built product fit just right. Great communication from the company and fast shipping. This fit my 2020 Cannondale Supersix Evo with SRAM Force to a Cyclops Fluid 2 trainer.

  28. Victor (verified owner)

    Fits perfectly on my Canyon Endurace on the Wahoo Kickr Snap trainer using one of the included spacers. I picked this axle specifically because it was noted that I don’t have to swap out the axles when going outdoors. Also appreciate the upgraded shipping. Thanks!

  29. Michael (verified owner)

    This is exactly the piece I needed, it fit perfectly, and it is high quality. I was recently given a bike trainer. I didn’t realize when I received it that my bike, which has a through axle, would not work with the trainer. Then I found the Robert Axle Project. They have a tool on the website that lets you find the exact part/right fit for your bike. Ordered the part they recommended. Fits perfectly and is high quality. Now I can bike the bike on the trainer or go for ride outdoors with the same axle. Highly recommend!

  30. Elizabeth Wierchowski (verified owner)

    I love this! I bought a new road bike and was in dire need of a way to put this on my trainer. I was helped by someone who knows bikes inside and out and he recommended this company. The axle shipped quickly and fit perfectly. The best part? I can ride outdoors with this and don’t have to change it out (some manufacturers make thru axle converters that are not meant to be rode outdoors). 10/10 recommend this company and their product.

  31. Nobody Jones (verified owner)

    Axle finder worked like a charm for my squirrely 2015 Specialized Diverge. Am now able to use my bike on the road or with my trainer effortlessly. Great to see the instructions come with obvious torque settings for each component.

  32. Mitch (verified owner)

    Exceptional service and product. Easy mechanism to determine which axle I needed for my Specialized Diverge. Received it way quicker than expected (especially under COVID constraints). Highly recommend!

  33. Michelle Haag (verified owner)

    Received fast and it fit perfectly. Most difficult part was getting the original thru axle out. I can use my cyclops trainer again! Very happy customer!

  34. Ulysse Meersseman (verified owner)

    Great axle ! I purchased it to use it on my Wahoo Kickr snap and it fits just perfectly my disc brakes bike.

  35. D

    I was a bit skeptical, but this site is great at assessing the right axel for your bike and situation! 100% perfect

  36. Sam Auld (verified owner)

    This is an amazing product. Works so well and easy to install, took me maybe 3 mins and i’m far from being mechanically inclined. In addition, the customer service I received was second to none. I highly recommend this company

  37. Joshua Dinwiddie (verified owner)

    Very well made, clever design. Fits a 2020 Canyon Ultimate disc perfectly with one of the included spacers. I really appreciated the “axle finder” tool, and the recycled/recyclable packaging was a nice touch.

  38. Vassilis Aligeorgas (verified owner)

    Perfect solution for my Cannondale Synapse to my Vortex trainer. Easy application. You take off the cap and free to go outdoors in a minute

  39. MegaSlippers (verified owner)

    I needed an axle to put my Canyon Grail on a turbo trainer. The Wahoo adaptor is a faff but The Robert Axle Project fits perfectly with zero faff. The axle finder is great and the support staff are really helpful. Delivery is also really fast.

  40. Ron W (verified owner)

    I ordered a Robert Axle so I could use my mountain bike with a new fluid trainer. It arrived within days in the mail and fit perfectly. The quality of the material and finish is very good. I could use it as my main axle for riding as well, but it requires a 5mm wrench to remove it if needed instead of having the lever on my original DT Swiss axle, which is only a minor inconvenience.

  41. Doan D (verified owner)

    Very solid axle. Works perfectly on my old Cycleops trainer. I appreciate the fact that I can use this axle for outdoor rides, too, and can remove the endcap on the drivetrain side if desired.

    If I had one piece of suggestion, it would be to have a handle/lever on the non-drivetrain side like a regular thru axle, so that on outdoor rides I can quickly fix a flat without having to carry a hex key.

  42. jay harrison (verified owner)

    Worked perfectly on my Santa Cruz Chamleon. Thanks for you assistance. I can now use my bike trainer that was a xmas persent.

  43. Jon Frye (verified owner)

    Bought this axle to fit my bike to an old Cycleops resistance trainer…if you have a newer bike with a rear thru axle (mine’s a 2018 Canyon Ultimate CF, disc brakes) it won’t fit a basic cycleops trainer (like a cycleops saris fluid 2). This axle solved the problem with no issues whatsoever…you can aIso ride this axle on the road without swapping in the original factory axle. I hope this post helps someone who is having a similar problem.

  44. Matthew Girard (verified owner)

    Used this for my Cube Nuroad. Fit perfectly! Great product.

  45. Jim Corcoran (verified owner)

    Needed an axel to sit my new bike on a trainer. Ordered one from Robert Axle, it came very fast, a few day, and is a perfect fit. Robert Axle is now on my go to list for bike axle’s.

  46. Igor (verified owner)

    Helped me perfectly with my 2017 Cube Litening attachment to Wahoo Kickr Snap.
