    I have a Focus Cayo Disc 3.0 with RAT thru axles and wanted to attach a Smart Trainer (Wahoo Kickr Snap) to train indoors. After grinding to a halt with Wahoo support – they said this was not a possible combination (even with their thru axle adapter) I decided to buy this axle. Since delivery; I’ve been using it daily & it works a treat. The kickr attaches perfectly & I can also leave the RAP axle in place (use as default during the Winter) if the horrendous Scottish weather abates & want to use my racing bike outside as normal. Very quick delivery (until it reached the UK!) with tracking & great support. Thoroughly recommend this product. Wahoo should really take note as the RAT thru axle is not a dead-end with their (or similar axle-connection eg Tacx, Kinetic etc) trainers !

    I have a Focus Mares CX with RAT and using this axle with a Wahoo Kickr Snap and a 700 x 28mm Vittoria Rubino. Axle works great and was easy to install with a nice instruction sheet included. It came with an extra 4mm thick washer that I installed on the drive side assuming it was just to protect the “special nut”. I have taken this out as I was concerned at the force needed to close the Snap on the axle. Flexed the Snap a good to close. But the Snap is BEEFIE! The bike tire does ride left of center or the trainer roller, but I think its fine. I don’t dare adjust the left side of the Snap to move the wheel to the center as this will just flex the Snap more upon closing. Looking at a potential mod to the Snap right side part that mates up with the Robert Axle piece. All good. Thanks

    Really nice Axle, very well made with nice tolerances (lovely fit and minimal play.) Very fast delivery to the uk too! My only negative is I fitted this to a Focus Cayo Ultegra disk 2016. The small Allen bolt that you remove from the RAT Axel nut and use to fit the Robert Axel Project adapter is too long and touches the rear cassette with the adapter in place. I got around this by sourcing another bolt and shortening it. Not really a big issue in the grand scheme of things! I would definitely recommend this axel to any RAT owner.

    Gorgeous product and GREAT support!
    Like Robert, I had an issue with the Focus Cayo stock bolt being too long. Chris was super responsive and worked with me to find a solution to the issue. As a note – I replaced the stock bolt (which is an M3x18) with an M3x16 bolt (M3x15 might be even better).
    So, while not perfect, I couldn’t be happier with the support! Great product & great people!

    A perfect and elegant solution. I’ve got a 2017 FOCUS Mares 105 AL and this works beautifully with the CycleOps Magnus Trainer. FYI, the CycleOps bolt adapter is not needed here because the length of the Robert axle fits perfectly. Thanks Robert Axle Project for being incredibly responsive and allowing me to mount my CX bike on my trainer for some dedicated indoor training.

    Had to make small modification to nut as didn’t require bolt hold moulding attached to nut! Apart from this it’s great!!!

    I have the Focus ax Apex and the rap axle for Tacx and to use the Focus with our Leggero enzo children Buggy. I can mix the Leggero Thrue axle with the rap axle. Perfect. Shipping to Germany was fast as described. Super Product

    I purchased this axle for my Focus Mares AL 105. I placed the order in the middle of the week, I received the shipping info the very next day and got my axle at the start of the next week. I’d say this was a very speedy and effortless order and delivery all the way to Finland.

    The axle itself was a breeze to install and it fits my bike and my Cycleops Fluid 2 trainer perfectly. I haven’t had the chance to try it outside yet but I’m more than confident it will handle outside conditions as well.

    Bought a thru axle for my focus cayo disc from these guys when I was told there was nothing available for a static trainer. Communication was top draw even with a slight mistake with the initial order. This was rectified straight away and the axle is currently on my bike now ready for some winter training.

    Would highly recommend to anyone needing these.

    Worked great for setting up my Focus Paralane. The quality of the machining is top notch.

    Hy, my girlfriend and I have a Focus Mares AX 2016 (Cycloscross) with RAT thru axles. We bought a Tacx Bushido Smart T2800 to use it with our bikes. Unsuspecting that we can’t use our bikes out of the box with the trainer. We thought that every bike can be used with the indoor trainer. Unsuspecting that there are a lot of different axels. We contacted the Tacx support, which sent us the link to the Axle Project. We ordered two axles. Now we are happy. After a few rides we can say, good axles! We do not change the axles any time we ride outside. You can also use the axles from the axle project outside.

    The shipping takes a time, but this was just a problem of the customer support in germany.

    Also the support from the axel project was very good.

    Great!

    I have Focus Paralane and Tacx Satori. Your 12mm Thru Axle for Resistance Trainer saved me. I love my new bike but R.A.T. system forced me to stop using trainer. Thanks to your Thru Axle I’m again on my bike since November working on my form for the next season.
    12mm Thru Axle works great, is easy to assembly and does the job! I recommend it!

    Perfectly fits to my Focus Cayo disc 2017. And it is the only answer to the question – how to connect Focus with Elite Qubo smart trainer )))
    Thanks

    Excellent! Very fast shipping and the package included axle ends for the different years that Focus has been changing them around. Very easy to install and fit on my Cycleops Fluid II perfectly. The best part is when the weather clears you just remove the axle end cap and go ride! I haven’t used my Focus axle since I started using this one and actually think its a bit stiffer than the stock. Just don’t forget to ring a multi tool on your ride.

    Product looks good and does what it is supposed to do. However, the customer service is outstanding. The axle got lost in transit with the carrier and in no time Chris send me a new one. Thanks so much

    Works great on Focus Mares and Kickr Snap. The instructions sound like they writte by a team of lawyers other than that it is all good!

    Fast delivery. Proper packaging. Lightweight and cool looking thru axle. Recommend specially to those who have FOCUS bikes because it is the best solution in order to use a indoor trainer.

    I have a Focus Paralane with R.A.T thru axles wanting to attach to a Wahoo Kickr Snap. I was told by Wahoo support that my bike was not compatible with this trainer, and tried to upsell me to their more expensive ones.
    I found this axle and decided to order it. Delivery was fast (1 week to NZ).
    The axle was easy to fit, and works perfectly with the trainer.
    I am very happy with this product.

    This is the only way you have to ride with your focus on a trainer period. The product is great I had an initial issue with assembling the parts but is because I did not get how to set it up. My suggestion would be to post a video on youtube with instructions cos on paper is not that clear. Anyway an excellent product that has saved my winter training. Thanks

    I have a Focus Cayo Disc with RAT thru axles and wanted to use an indoor trainer during the winter. This was the only option that I could find. Very high quality product that fits and works perfectly. It is easy to switch between trainer and outdoor riding without removing the axle. I just leave the axle on all the time. Would definitely recommend this product. It is actually a significant upgrade from the stock axle system.
