    I needed a trainer axle for my Giant Defy Advanced Pro 1 road bike. Giant plans to offer a trainer axle, but my LBS couldn’t say when it would be available. The Robert Axle website made it easy to determine which of their axles would fit. They shipped it promptly, it’s a beautiful piece of craftsmanship, the included installation instructions were clear and simple, it fit perfectly, and I’ve been riding my trainer while the snow piles up outside. Truly a quality product from quality people – highly recommended!

    I needed a trainer axle for my daughter’s Giant/Liv Avail Advanced 2 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 an axle for my Domane 4.5 Disc bike to replace the one that I purchased from a different source earlier. The axles are perfect fits. Great group with whom to do business. I have no reservations recommending the company or product.

    I moved to a new bike (TCX-SL2) which has 12mm thru axle rear. Tried several other places to find the right axle to allow me to use my CycleOps trainer with no luck. These folks sent exactly the right part, it’s well made and it came quickly. I would recommend them without reservation. Thanks!!!

    Bike: Merida Scultura Disc
    Trainer: Wahoo KICKR Snap
    Sizing: CHECK using the chart they have; if in doubt email them, they are very helpful and prompt in replying

    I love riding both indoors and outdoors, and this axle allows me to do just that without the headaches of switching axles etc. There is nothing worse than having to unscrew the axle, replace it, keep the bike from wobbling, align the hub/frame,…. all to make a 4 minute commute to the shops to get that one zucchini my wife needs, and then reverse to process to get back on the trainer. Now, I just the leave the axle in and forget about it.

    From a pure-training point of view, when the weather does a get a bit chillier, it means that I can warm up on my trainer at home and all I have to do is take the bike out of the KICKR Snap and I start my outdoor training nice and warm.

    Wahoo sells a similar product for mounting a bike on the trainer but it is a rip off, not nearly as functional and they do not encourage it to be used outside.

    I checked sizes with the comparison table and after that I was very confident on which axle to order. The axle attached beautifully to a Giant Defy Advanced 2 (2017) running on a Tacx Bushido Smart trainer. As a matter of fact the axle contact with the trainer arms is way more precise now as compared with my previous experiences with quick release axles (less jiggling). Fast delivery. No trouble. Recommend 100%.

    Hello, I own an outdoor store in northern Michigan which includes a bike and ski shop. I recently ordered a Giant Avail Advanced Pro for my wife and upon bringing it home to put on the trainer, quickly realized it had a rear through axle. After looking through our shop catalogs including QBP and J and B importers, I came to the conclusion I had to look online. I came across these guys and after sending an email and getting a quick response I ordered and received my axle in two days from California… Incredible. Though we are a Brick and Mortar shop, we ship skis all over the country and our customers love our personal service and that’s what I love about the Robertaxleproject!

    I’m using this axle with my 2017 Giant Defy. Works great in my trainer. Best of all, it was reasonably priced AND actually available when nothing else was.

    I haven’t used it on the road since I like my wheel to be removalble without tools when I’m out but it’s good to know that it would t be the end of the world if I forgot!

    I recently purchased an in door bicycle trainer to use it on my Scott Solace bike; just to find out that the universal axle that came with the trainer did not fit. Then I went to the local bicycle shop to purchase the right piece. That shop didn’t carry the piece, however they did the research for me and they recommended me The Robert Axle Project (TRAP). I went ahead and provided the right information to TRAP. In a matter of days, I had the part. Everything is working perfect. I am pleased with the product and the quality of the service. Highly recommended!

    This model has proven to work with my Giant TCR Disc combined with my Wahoo trainer. Ordering a second axle for my wife’s Avail.

    Perfect!!! Giant still doesn’t have trainer axles for their Defy Advanced bikes, so I had to turn to Robert Axle. Fast shipping and the axle works perfectly!!

    Works great with my Giant TCX Advanced SX and Tacx trainer! Feels nice and solid in the trainer, and shipped fast to Canada. The bike shop said it might be weeks before I could get a trainer axle from Giant so I sourced this one.

    Axle worked perfectly for my new Look 765 Disc on an older Minoura trainer. Used the measurement guide, and with the confirmation from the Robert Axle team – the axle arrived 3 days later and worked splendidly. Fits really well on trainer and the bike feels stable and secure.

    Ordered for a Pinarello Gan, fit perfectly with my bike and my CycleOps Jet Fluid 2 trainer. Much different size than what was imprinted on the factory axle, so definitely check out the sizing worksheet. I didn’t think there were axles available sized for my bike, but fortunately that was wrong.

    I bought the manufacturers (CycleOps) trainer axle for my Scott Addict Gravel 30 and it just didn’t work. It came with a bunch of spacers to supposedly make it fit but it was too long even with the new trainer adapter I bought with it. I was ready to give up on it when I found The Robert Axle Project and decided to give it one more try. The axle fits perfectly with no changes to the trainer and is simply a superior design.

    Purchased a Cyclops trainer and the rep there suggested this site to purchase the necessary axle to fit the trainer for my Liv Avail Advanced bike. The website was easy to use and helpful in choosing the correct size for my bike. Would recommend.

    Wonderful product. I bought this for my 2018 Giant Defy Advanced 2 to fit my indoor fluid trainer and the product performs better than I expected. The ordering process was easy and straightforward, and the shipping was quick. If I ever need another axle adapter The Robert Axle Project will be the first place I look.

    I needed an axle for my Orbea Terra so that I could use it with my indoor trainer. My local bike shop said that I would need to buy a new trainer because no one made an axle that would work. I was surprised when I found that Robert Axle made one that exactly fit my bike. Easy to install and I did not need to buy a new trainer. It is a great product specifically designed for my bike and trainer. I highly recommend Robert Axle Project
