I’m looking for a small part for some Tiagra brakes…the nylon/black plastic cam that ‘closes’ the caliper after fitting the wheel.

Are they even available? I’ve tried Petra Cycles which from memory stocks lots of random stuff…any one else?

The caliper is £21 which doesn’t seem to bad…until it breaks again next year…

Or any bodges if its a common failure? The cam is held on with a torx bolt…

Is this like yours

I don’t think they are avaialbl separately.

Look up the Madison website.

On the tech doc the part is not labelled, its in front of where part 11 goes.

Will check Madisons site. Thanks

if its not labled on the tech doc with a part no then its not available.
