Overall Product Rating 5 / 5

A good replacement for OEM thru axle

I recommend this product

ConsPrice is too high

ProsFitted my bike, seems well made

I bought this for my 2021 Surly Disc Tourer, after the aluminium washers on the original axles disintegrated. I contacted Surly who said they don't sell replacement axles, and these were the only option I could find available in the UK. The price stung, considering it's basically a long M12 bolt, but they've done the job which is pretty much all you can say of an axle. Probably a particular quick of the Surly Disc Tourer dropouts, but I decided to use some nordlock washers on the non-threaded side to make sure they don't slip. This arrangement is working great so far, although I didn't test the axles without these.

Hi, my current through bolt has no spec on it. It is M12 and 1.5 pitch according to the sheet provided. 106mm unthreaded and 13mm threaded, will this bolt be ok? Thanks, Mark

Can you tell me what the thread length is on this?

By Mark Watson

My current through axle is marked "12.0 *106.0L*M12(P1.5)*14.0L" - which I guess means 12mm diameter, 106mm unthreaded, M12 bolt with 1.5 thread pitch and 14mm thread length (making a total of 120mm length from the axle head). So will this bolt fit as a replacement? Thanks, Mark

SJS Customer Service:

This bolt is most likely to be the replacement you need based on your proved specifications. Thread length on this is approx 16mm.
