    Product did not come with the bolt action slider tuber, does not fit my Saris M2 trainer without it. Do not buy!!

    Very well made and looks solid but threads are not compatible with 2020 Trek Madone. It was returned.

    I used this to mount my 2015 trek domane to a saris m2 trainer, and it works perfectly. It took a couple tries to get the spacers adjusted properly, but it’s solid and it works well for indoor cycling.

    Unfortunately I need an M12 x1.0 as shown in the picture for this product and what was shipped is an M12 x 1.5 which is too course a thread for my bike. I cannot use this part.

    Seems to work, directions are not very helpful though.

    Saris immediately made it right and shipped out the missing part.

    Does NOT include “ shorter bolt action slider tube“ as specified in description. Thru axel works on my bike but the trainer doesn’t. Now I have to track down a shorter bolt action slider tube.

    The thru axle worked great but didn’t come with the shorter slider bolt. I called Saris customer support and they did a supper job and sent me the slider.
