It looks like something bolts on to it but I can't think what it would be. I know it's stopping me from fitting a bigger rotor though. Any ideas?

what frame is it?

fitting your bike prop stand 😆

it's a Scott Aspect 20 hardtail.

What he said ^^^^ a mount for Scott's own kickstand!

I was half joking but couldn't think of anything else that would go there .Strange to see that on a reasonable bike though.I know they are more common on the continent

I can't remember which brand of bike but some one did make a bash guard for disc rotors, it could be for that.

Believe me, its a kickstand mount!!!

A kickstand mount. That does make sense. Thanks.

shame, a bash guard for the rotor would have been so much cooler.

the obvious fail is that the chains on the wrong way around

No it isn't.

Umm…don't Rohloff hubs have some sort of arm that would bolt onto something like that?

is it a dedicated mount for scott's own Engerlund flag ?

or something to do with rohloffs

or maybe a vase for flowers

or a cadence sensor

(or anything else, to make twohats cross 😉 )

its a useless flat welded plate with two rubber grommets, would have thought that much was obvious
its otherwiswe known as a 'B-DUB' or bigger disc upgrade buggerer

That's the best explanation so far iain1775.

Good to see one manufacturer specifying locating holes for the torque arm of a Sturmey-Archer drum brake 🙂
