    Just freed the pistons on my avid juicy 3s. Putting the pads back my brain was so absorbed with left right on an up turned bike that I trod on the rotor.

    A quick bend back sugests it'll never be flat again. Is this correct? Do I spend the afternoon flattening or looking for a new rotor(185mm). Ride set up for tomorrow….

    it'll be fine
    just use an adjustable spanner to tweak it

    I could never get my Magura rotor straight enough to work well again. See how it goes.

    It wont be perfect but as mentioned above you can tweak it back with an adjustable spanner, a rock must have hit mine at BBF as after a lap the I noticed the wheel would barely turn at one point when it was on the stand straightened it up in about 10mins and was good to go. Make sure you give the disc a spray with disc brake cleaner after otherwise you might end up getting oil or greese on your disc and ruin you pads as well!

    Are you based in Ampthill by any chance (going by your user name!)? If so I'm in Barton le Clay and have a 185 disc you could borrow until you get a new one…

    cheers Bullet yes I'm in Ampthill. I'm now on the road

    thanks for they very kind offer

    Everyone else thanks the spanner got my close enough

    I thought I'd knackered the pads but cleaning the disc and then round the block with loads of nraking on the hills has got my back to acceptable performance….

    Ampthill is all just golden hares, init.

    I think if you've stood on the disc, this is possibly quite a bit different from a rock strike – the sort of thing people recommend fixing with an adjustable spanner.

    I squashed my disc similarly, tried bending it back with the adjustable spanner technique and couldn't ever get it back in shape. I think with large width bends in discs – as opposed to sharper rock strikes – it's probably best just to gently bend it back with your fingers. Less likely to do more damage that way… 🙂

    Either that or I'm ham-fisted.

    rotors are cheap as chips from superstar and they seem to be tougher than avid ones which are either bent when they arrive in the post or bend soon after. I have 6 ss rotors and all are straight as.

    No worries, glad you're sorted. I'm on a blue Hustler so may see you out and about on the Barton Hills/Chicksands/Woburn sometime…

    Can you swap a 185 Avid disc for a 180 Supertsar without moving the caliper?

    I don't think so – I emailed SS and asked that and they reckon not. I have now managed to get my Hope floating disc to fit again after putting new Fox 32 TALAS forks on. Can't work out why the Hope disc feels so much better than the Avid disc, looks like they are made from the same grade of stainless steel? Whatever, the Hope is miles better so chuffed I can use it again…
