I tried to reduce the reach of the levers but turned the hex the wrong way and snapped the hex screw. looks like a specialist part.
where can I buy a replacement?
will my brakes still work the same with this broken (and now removed)?

Get a bolt that fits and cut a groove in it for the circlip??? or speak to LBS
does this part do anything else than adjust the reach? will I be able to use the brakes as normal (but at full reach)?
Try it!
Just had a look at
Does not seem to be available as a spare but I have replaced one before from a donor lever and it is a pain in the arse if it's under warranty try and get it fixed.
it looks like the parts available on the red levers (I'm presuming that it will fit the rival)? If Ii can remove the lever blade then would it not be an easy fix?
