sorted out last time by toeing the front brakes and it went away. On the way home this evening it was wet and the judder has come back. Pretty unnerving.

Any ideas how to sort it?

The pads have worn, do the toe-in again.

What's your current brake set up?

That never occurred to me.

Cheers.

brakes are Vs (Cables)

Is the front brake hanger mounted at the headset on yours ? If so then it's an "old" model and you'll continue to get brake judder over time. This can be fixed by fitting a replacement hanger (Kona/Spesh/Tektro) to the top of the fork.

any links to images of the differences?

You don't need the hanger if you've got V's though…but you'll never stop the judder I don't think (and I found you continually had to fettle to get any stopping power).

I'd get shot and get some canti's and an up hanger…although I don't get much judder with a headset mounted hanger mind.

Up hanger

headset hanger

Top one goes up from the mudguard mount in your forks, bottom hangs down as a replacement to one of the spacers in your headset stack.

mine only has the wire mounted at the headset and then it attaches to a wire staddling the brakes.

Now I'm confused as to whether you have V's or canti brakes! 😉

Get some Easton EC90 forks. I pissed around with mine for way to long before just giving up.

>mine only has the wire mounted at the headset and then it attaches to a wire staddling the brakes.

Same as mine. It's a design flaw which Spesh have now fixed on newer models. The "fix" is to fit a hanger at the top of the fork (through the mudguard mounting hole).

One of these http://www.petracycles.co.uk/product_info.php?language=en&currency=GBP&products_id=57966

or the Spesh part itself

And the reason why it happens on the headset mounted hanger

They fixed it last time by fitting Mini V's. Check them out!

That article could have been about 1/3 as long.

If Mr Zinn is correct, how come this was not widespread in canti equipped mountainbikes?

I'm with Singlespeed_shep on this. I've tried all sorts on mine; different cantis, 2 different types of cable hangers (hanging from above headset and up from fork crown) mini Vs and most recently normal Vs with V brake compatible road levers……and they still judder. I've given up on them. My LBS only recommends alternative forks now.

I thought it was an issue with the flexibility of the forks – with them fancy "zertz" bendy bits making it worse.

16 seconds too late!
