Bent brake disk

irvs

I've managed to slightly bend my rear disk, not too bad but it's notice able. It's a standard tektro hydraulic disk on a giant revel 1, is the disk a direct replacement or do I have to change the whole wheel???

Thanks Neil

No you don't have to change the whole wheel, just replace the disc, cheap enough anyway, but if its not bent that bad you could try and sort it there is a thread in the faq about sorting out discs

EH_Rob

the disc can be replaced - try superstar components for cheap bits. be sure to order the size you've currently got, probably 160mm.

And whether it's 6 bolt (most likely) or splined fitting.

Disk can be replaced. 6 small bolts will be attaching it to the hub (centre of the wheel).

Check here or here for replacements.

If it is not bent too badly, you can bend them back with no ill effects. I'm sure somebody else will be along soon to tell you how to do this.

Only Shimano discs/hubs use the spline fitting I thought?

Nope, I have splined mavic wheels.

I've learnt something new today then

dt also use splines.... and some use other threaded sorts, never seen them about

Cheers for the help I'll have a look when I'm home from work.

Thanks neil

if the rotor is not too badly bent you can use pliers or an adjustable spanner to straighten it out

Just wondering would it be a good chance to upgrade the disks (is there an upgrade or are they all basically the same)???

Neil?

cooldad

They are all basically the same.

I have splined Fulcrum wheels. Annoyingly a standard splined to 6 bolt adapter won't fit neither

Try bending it back first. Adjustable spanner is a great disk fixer.

+1 gazzillion potatoes to OP for not calling it a rotor.

Nope, it's a rotor. I would try to straighten it, before buying new. You may bend it again, eventually you'll have to learn how to straighten it. Although it's not big deal if it's slightly out of true, it will never be perfect. Plus, it saves money. Just saying...

thanks everyone for the info on fixing the brame "ROTOR" lol

thanks neil.

Just use an adjustable spanner to straighten it out a bit, I don't think any of the rotors on either of my bikes are totally straight...
