How long is your axle?

I have a boost frame and it wasn’t until I got a 12mm axle for my non-boost frame that I compared them and discovered they are the same length. This means there’s not a lot of thread on the boost one doing anything useful. The axle was supplied by Scott with the frameset so wondering if this needs changing or if it’s fine.
Can a few people with Boost rear measure their lengths please? Just the insertable bit please, mine is 167mm
thanks

It generally varies from frame to frame, depending on the thickness of the dropouts. You should end up with near full thread engagement without bottoming out before the hub is clamped tight, if it’s too short then take it back to your dealer for their opinion.

Sounds about right to me…….

@Andy R my non-boost is 167 too which is the worrying part.

To follow up on this, the LBS confirmed the supplied axle is dangerous and is shorter than a boost one should be so are contacting Scott for replacement.

Could you specify the model of bike so that other folk might check theirs too?

Cheers

It was a Scott Genius 700 plus tuned frameset. I get the impression that this may happen a lot though so everyone with boost ought to check. Just look at the dropout by the rear mech, your axle should be fully engaged to the end of the threads, not have a 5mm gap 🙂
