Description
- This Trainer Axle is designed to adapt your high quality bike to your on-wheel 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 5mm 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. Our the trainer axle ends will extend 15mm past your frame on each side.

Ever so impressed with your company and this product! The axle was shipped to Canada and installed on the bike within 4 days of making our online order. The axle was easy to install, fit perfectly, and is compatible with our elite trainer. The accompanying instructions were very clear and detailed. You website is very user friendly. The brand-specific dropdown menu is very useful and inspires confidence that your product is well-designed. Thanks for saving the day!!!!

Bought a 12X142mm for my indoor training on my Cycleops Jetfluid Pro. The website fitting guide said it fit: it is a very close call…You’ll need to “stretch” the trainer arms by hands while pushing on the saddle.
Once seated, it work fine and is very sturdy.
I won’t put back the formula axle next summer; I’ll simply remove the conic ends of this better axle.

I needed a trainer axle for my daughter’s bike but couldn’t find one until I found The Robert Axle Project. Their customer service and support was excellent in making sure that I ordered and received the correct axle. The product is excellent, so much so that I ordered another axle for my Domane bike to replace the one that I purchased from a different company earlier. The axles are perfect fits. Great group with whom to do business. I have no reservations recommending the company or product.

Well designed and manufactured to perform a basic function which it does impeccably. Not much else to say
Eric (verified owner) –
I have a 2017 Norco Threshold C and a Whaoo Kickr Snap trainer. The 174 x 1.75 axle work perfectly as a replacement for the stock axle. Saved my about $25 over Wahoo’s. Very happy with the axle.

Excellent product. Robert Axle Project helped me figure out which axle I needed to put my cyclecross bike on an indoor trainer. It works perfectly, and the product was shipped in a day or two. Very good product and service!

Bought the 12mm Thru Axle for Trainer: 174mm x 1.75mm thread. This fit both my ’17 Niner RLT and my ’14 Trek Stache 7. Awesome that I can use it for both bikes. Makes it so that either can fit in my 12 year old trainer.

Installed on Santa Cruz Stigmata 2018 without issue. Looks great and works wonderful!
I didn’t need the washer that it came with, but glad to have it just in case.
Kirk –
Well made. Great fit. Works.
Charlie (verified owner) –
Fits my Stigmata and Kinetic trainer perfectly. Highly recommended.
Alexander K (verified owner) –
Exactly what was needed. Originally used a cycleops trainer thru axle, but it didn’t quite fit my Blackburn trainer and wasn’t quite as stable as I’d like.
This axle has the same exact same shape ends as a standard trainer skewer, and doesn’t need any fighting with spacers, or hoping the trainer is wide enough to fit the unnecessarily enormous axle.
Ken Cox (verified owner) –
This axle is perfect in every way for attaching my RLT to my old Trek trainer. I really appreciate that I can use this same axle outdoors (instead of having to swap back and forth like lesser products) because this winter’s fickle weather has me popping the bike on or off the trainer every other day. I asked a question by email about the washer that came with the axle and received a quick answer that it wasn’t needed for my bike. It’s really satisfying to see a company solve a specific need so thoroughly and perfectly.

Axle Finder database provided me with the correct axle for my bike trainer. The fit is spot on. And it arrived within a few days of placing my order.
Chad (verified owner) –
Works perfectly. Very happy with purchase.

Bought the 12mm trainer axle 174×1.75mm thread (TRA201) to be able to use my Trek Checkpoint bike with a 12 year old Computrainer. The website fitting guide was great to help me figure out which axle I needed for my bike. The axle was shipped fast and the installation instructions were very clear and easy to follow. The axle fits like a glove with no spacers or adapters needed. Communications with the company was great. The only improvement I would want would be a longer than one year warranty since this is after all just a metal axle! I would definitely do business with The Robert Axle Project Company again and will highly recommend them.

Super easy way to get your TA bike on a “dumb” trainer. Even with the supplied washer, it fit with room to spare on a Cylceops Fluid 2. If you have any weight weenie aspirations, I would use another axle while out on the road/trail.
Sarah (verified owner) –
Currently using it on my trek crockett 5 disc (2018) and it fits perfectly. Was also easy to install!
Craig Trevillyan (verified owner) –
I’m so impressed with 1. how easy it was to find the perfect axle for my bike and 2. how excellent shipping was. I received a recommendation for The Robert Axle Project from a friend over at The Bike Shop @ Woodward Park in Fresno, CA. I needed it shipped all the way to Nanjing, China where I am currently living. A few clicks on their website and just days later, the axle arrived! I rarely get packages successfully shipped from the US. This was the easiest transaction. The axle feels like more of an upgrade to the stock one that came out of my 2018 Niner RLT 9. Now, on “bad air days” I can just toss the bike on a trainer and ride, or enjoy a nice grind outside using the same axle. I would highly recommend The Robert Axle Project for their products and customer service.

Bought this for my Tacx Bushido. Fits great, works as it should. No complaints here:)
Bob (verified owner) –
Ordering was very efficient, arrived quickly, quality very high, seamless installation in under five minutes. In many ways it’s better than what I had on my Niner RLT 9 Steel. It now works on my trainer. What’s not to like!
Andy (verified owner) –
I purchased this axle to fit my Trek Checkpoint to my Kickr Snap trainer. It is a well-built, quality axle. Glad to add a bike component that’s still made in the USA!

Spot on for my 2017 Trek Crockett! Easy to install and works great on my fluid trainer.
Easy to order, fast shipping, and great communication!

This was exactly what I needed for my Trek SL 5. Thank you!!
Allen Day (verified owner) –
Listing was accurate for the application. The axle is nice. No one really wants to pay a bunch for an axle just to chase the lack of standards on how to attach a wheel to a bike so they can use a trainer. At least Robert Axle.gets it right and the product is nice.
Steven Kennedy –
Perfect fit. Works great.
LARRY L ROGERS (verified owner) –
My bike shop recommended Roberts Axel Project to me. I ordered the wrong size but Troy in Customer Service was great in getting the correct axel to me. It fit my Trek AL 3 disk bike perfect for those rainy days when I need my bike Sportneer Bike trainer.

The axle I bought for my Lauf gravel bike is high quality and fit perfectly without the included spacers. I could never have ordered the correct size without the helpful bike lookup on the website. Thank you!
Bruce (verified owner) –
Perfect fit. The guide for sizing was the most helpful I could find online. Order came quick and was a good price point compared to competition.
Mounted bike onto indoor trainer and it is working great and easy enough to just unscrew the drive side and you are good to hit the road.

We bought axle for my trek checkpoint SL5 ..and it fits well and we like it.

Excellent replacement for my standard thru-axle. Where I live, the current season will do some wacky things to the weather. Now I don’t have to go through so much prep to ride inside vs outside when the forecast suddenly changes!
Leslie McIntire (verified owner) –
The Axlerod Project allowed me to select the right thru axle for my bike. The thru axle I purchased worked well with my stationary bike trainer. I found the thru axle easy to install and to remove.

Super easy solution to attaching my gravel bike w/ disc brakes to my Saris fluid trainer. The order shipped quickly and the axle adapter works perfectly.
Hannah (verified owner) –
Perfect fit and effortless install for my turbo trainer. Happy to be able to get this well manufactured part from a small business.
Jason Sewell (verified owner) –
I searched for a skewer and bought several for my new bike and none of them worked. The local bike shop recommended you guys so I ordered the axel from you guys. Honestly I was sticker shocked but when I got the axel it fit perfect and ended a frustrating shopping experience. Thanks for offering premium axels that are guaranteed to fit!

I needed a rear axle to put on my bike for indoor turbo trainer use and outdoor riding. The selector tool on this site was so easy to use to find the correct axle for my bike. The axle fit perfectly and the end pieces fit great in my turbo trainer. I highly recommend these axles!
