12mm Thru Axle for Trainer: Mavic Speed Release Rear Thru Axle
$ 54.00
This rear thru axle is specific for using your Mavic Speed Release bike on a wheel-on trainer. The thread, a “double lead-in” thread, is proprietary to the Mavic Speed Release system only.
Purpose built to adapt your thru axle equipped bike with your wheel-on trainer, such as a 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo and many other trainers. Our goal is to fit the thru axle to your bike perfectly, so we minimize spacers and extra parts, providing a clean, high performance axle for your bike. Train, warm up and be race ready and fit for the season.
Yes, we have a Lightning Bolt-On Axle for your Mavic Speed Release bike – find it here!
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: BKool, 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.

For a third party part i was a little worried, but the quality is there as soon as you remove it from the package!

This is the only producer that offers axles for MAVIC Speed release systems. Two of the biggest trainer manufacturers (TACX and ELITE) don’t. Perfect!
v (verified owner) –
Fit was perfect for my Cannondale with the MAVIC speed release axle. There is plenty of room on the ends for my trainer to attach to, and it doesn’t scratch up my derailleur hanger. 10/10 recommend
Anton (verified owner) –
Bought for my Cannondale SuperSix EVO that has Speed Release 12mm axle threads. Could not find adapter for my Tacx basic trainer, by a chance found this Project. Great communication and fast shipment.
Gregg (verified owner) –
I purchased this for my 2020 SuperSix EVO for use on a KICKR SNAP after reading Anton’s review. It never even crossed my mind that the EVO had double-lead threads for the thru axles, and that the KICKR adapters Wahoo sells were only single-lead! I went from super frustrated – thinking I maybe had to return the SNAP and upgrade to the far more expensive wheel off trainer – to super relieved within minutes when I found this site. Build quality seems great, and it fits beautifully. 10/10 would recommend. Y’all saved me a lot of sleep and money

Problem solved! This nice and high quality axle allowed to fit a Cannondale supersix evo onto a Tacx Satori trainer. Top!

Like many other reviews here, I own a 2020 Cannondale SuperSix EVO. After some searching, I was glad that RAP had exactly what I needed (double-lead threads). It arrived quickly, and immediately I could tell it was high quality. It installed in seconds, and works perfectly. I’m also impressed that they thought through the design so well, that I can use this on outdoor rides as well just by removing the extra nut used for the trainer. So, I don’t have to swap skewers anymore; unless I want to. One less thing to remember on those days when the weather is good enough for an impromptu outdoor ride. Love it.

This axle was a perfect fit for my Cannondale SystemSix. I had previously tried all the Tacx thru-axles but because my hanger is a “double-lead”, none worked. Then, I found this website… The customer service is great, I had a question to make sure if this was the correct thru-axle, the reply was swift, and actually when you create the order you are asked to confirm the bike model etc… So they really want you to select the right one. Delivery was quick too, so it’s all positive from my side.

I have a 2020 Cannondale CAAD13 and it took me so long to find a thru-axle that fit my smart trainer and my bike. So thankful I found this product! Works like a charm!
Bas (verified owner) –
Bought an axle for my Cannondale Supersix Evo 2020 to use with my Wahoo Kickr Snap. Works like a charm! Perfect fit, good quality and I can leave the axle in my bike for outside use so no need to swap axles all the time. Also, very quick delivery (within 5 days) in the Netherlands. Perfect!

This axle was exactly what I needed to be able to put my CF bike up on my smart trainer, and it is also great to use on the street! It fit perfectly on my SuperSix EVO and into my Saris Smart Trainer.
Nick (verified owner) –
Works perfectly with the Kickr Snap and the CAAD 13! Much better than Wahoo’s trainer axle package. Great customer service, too.
Mike (verified owner) –
First off – fantastic customer service. Shipper (who shall remain unnamed) lost the first shipment, so shipped out a second order until the lost one was found. Axle works perfect on my Cannondale carbon for the use on the KICKR. High quality. Thanks guys.

Fits perfectly for my SuperSixEvo 2020 and Kickr Snap.
Big thanks to RobertAxleProjects for this.
Like many others I first ordered the Wahoo ThruAxle Adapter only to find out that it will not fit. Don’t look any further, get this one.
Ron (verified owner) –
Was a little worried that this purchase will be another fail. I tried few aftermarket axle for my Mavic double lead axle and nothing worked. I almost returned my bike. Then random guy in my bike community mentioned the Robert Axle Project. Ordered online and came in very fast! Fits like a glove. the BEST part is, you can use them outdoors! just unscrew the end cap fitting for the trainer and you’re good to race!

Fits great and works great in my Canondale Topstone carbon with Saris Fluid trainer.

This axle saved me from changing my Tacx Blue Motion Trainer for a more expensive one that I dont really need. Great product + fast shipping. If you have a promo code, do not use it : This axle worth its full price
Chris (verified owner) –
Perfect fit, exactly as described. Been looking for ages for something to fit to a Cannondale 2019 Super 6, thrilled to have found it! Very fast delivery, arrived in New Zealand in about 5 days. The order system double checks a couple of times that you’ve got the right part. Very impressed!

It’s true, I couldn’t find an axle with a double lead anywhere. Somehow I fell upon this website. At first I wasn’t sure, but once it arrived it proved itself worth it !
Many thanks guys, you have saved a lot of people who even the “trainer” companies haven’t thought about ..
Well done
Alex (verified owner) –
Saved me just like everyone else said it would. Worked perfectly for the Mavic double lead axle. Thanks very much
Dan (verified owner) –
My third RAP axle. Needed the chat support folks to confirm I did indeed need a new one for new bike, Canondale Topstone Lefty 3. But they are solid and I wouldn’t be able to use my trainer without these. Life saver probably isn’t too strong praise. I wish RAP a long and successful business!!

Fit was perfect to attach my CAAD13 to a Lifeline (wiggles own brand) TT-02 fluid trainer to my bike. Quality axel, quick shipping!

Fits on my Cannondale topstone to install on home traîner. Perfect to perform positionning on new bike.
Easy to find the appropriate axle with the chart, and good tips from the team for installation.

Got this axle to attach my 2020 Cannondale Supersix Evo to a Kurt Kinetic wheel-on trainer. Kinetic’s through axle adapters are only available as a single-lead, not the double-lead used on the Supersix. I initially thought I was going to have to resort to the clunky solution of using a (single lead) Synapse derailleur with the trainer axle and the Supersix (double lead) derailleur with the stock speed release axle, but then discovered the Robert Axle solution. This axle is well designed, high quality, and a great solution to using bikes with the double lead system with a wheel-on trainer.
Mario (verified owner) –
Fits perfectly! I’ve got a Cannondale CAAD13 with a double lead Speed Thru Axle and no other company was able to give a Trainer Thru Axle that could work. Great service and very professional. Would definitely recommend.

Excellent customer service- answered a question about this product I submitted with the order before confirming the order and shipping the product. High quality, works perfectly on 2020 Cannondale SuperSix EVO.

Finally, after purchasing the wrong thru axle for using on my trainer, I found The Robert Axle project. I supplied the specs for my Cannondale Supersix Evo and got the thru axle that works perfectly. The fit and finish are top notch and equal to the standard thru axle that I use when riding outside.
Tim –
Machined just right, fits the bike and the trainer well. Looks nice on the bike so I’m leaving it on full time for now. I will recommend to friends and buy axels from here again for sure.

Bought for my fiancée who purchased an Orbea Avant H30-D with a 12x142mm rear thru axle with double-lead threads. We were a bit worried she wasn’t going to be able to use it with our wheel-on Tacx Flow Smart Trainer. Luckily our local bike shop recommended The Robert Axle Project, and thankfully we were able to find the thru axle we needed very easily. It arrived earlier than expected as well. I definitely recommend this product and company. 10/10

Works perfectly on my 22 Orbea Orca M30 for training on a Wahoo Kickr Snap. Fit and finish is excellent and feels just like an OEM part. Well packaged, delivered across the country two days earlier than expected. After purchasing the thru axle adapter kit by Wahoo that did not work with my Orca as it did not utilize dual-lead threads, I found this solution easily using the axle finder on this site. I am so happy with this product and recommend this to anyone in need of an axle, you will not be disappointed. Absolutely wonderful!
Jacob Hamblin –
I have an old trainer that doesn’t fit any of my modern bikes. I was going to give up on trying to use it again, until I found this site. I ordered the through axle for my Cannondale System 6, and it fit perfectly, and I’m back on my indoor trainer again, very happy!
