I recommend this product
ProsLight and reliable
Very well designed and manufactured, the finish of the product is excellent.
It fit my bike perfectly and looks a lot cleaner than the big original axle.
I've had several rides with it and it shows no sign of coming loose or any other issue.
Lastly, it saved over 40g compared to the standard axle that came with the bike - just 29g!!!
Highly recommended.

Would this be suitable to replace a 124mm long thru axle?

Could you also tell me the thread length? The one I'm looking to replace is L:124mm TL:16m TP:M12x1.5
Hello & thank you for your enquiry.
To be further accurate with your thru axle question, i would ask for the following information that will then allow for input into The Robert Axle Project Axle Finder - front / rear, fork type, ebike - yes or no, bike brand, hub size. This will allow for an accurate axle identification.
Kind regards, pc 30/8/23.

I've just purchased a set of RobertProject thru axles off you for my Cervelo S3 disc choosing the ones recommended by the companies website. On arrival they are the correct length diameter and having matching thread pitch but the thread length is slightly longer. Before I fit them, I just wanted to check this is ok? I assume as long as they are torqued to the correct level the fact there is thread against hub body is ok? Many thanks
Hi there,

Yes this will be absolutely fine for you.
