please..

ton, massive hijack. You mentioned today a source of XTR copy pedals. Can you supply a link?

(Apologies for hijack)

🙄 what have you done to it?

got too much air….

i have done nothing to it.
i just want to ask a couple of ventanaesque questions.
you lot wouldnt understand…. 😉

i’ve got a ventana

is it about the “bottoming out” issue? 😉

I think Vortex racing has one

oh come on, what was the question?

very noisy back brake.
seems to be resonating through the rear triangle, but only when i freewheel.
like tooooo noisy.

We want to be Ventana owners.

😉

bastid 😡

had the mount aligned?

Who me?

That’s not nice ton.

sounds like your back wheel might not be seated properly? could it be that there’s more paint on one side of the drop out than the other?

stu, thought it was one of these 😉 😳

disc mount is aligned, frame is bare alloy.
only does it when not pedaling.

I think we need to save a bit of cash first though……. 😥

Maybe by this time next year.

You got another wheel you can try in there?

stu, you serious..
i was gonna try another wheel. thinking it might be flexing??
wheel is vert robust custom jobbie tho.

I’ve had 2 never had that problem,

It obviously can’t be the paint as there is non Mrnutt!

Build quality is usually spot on with these bikes, so i would be surprised if it was the alignment of the brake tabs or rear triangle.

Have you tried the brake on another bike, it might be worth a try to eliminate one thing or’tuder.

Seems wierd that it does it when you freewheel.

almost as though the pull of the chain is straightening the alignment?

Is it a Hope hub?

Vortexracing
brake is off my hoss, worked perfect on there
when i loosen the mount and recenter when loose it stops for a while then starts again.

hub is a dmr.

I’d try another wheel first as it’s easy to do and will at least eliminate one thing.

will try a wheel 1st, then a differant brake.
have slx on it at the moment, pretty well cooked on a descent of garburn today.
gonna put bb7 with 200mm disc on it.
power to burn. 8)

Try the Ventana forum on Mtbr.

If this is a fairly old frame it could be that the bearings are worn!

Ventana solo or ECdM tandem? When we built Nancy the tandem I took the Hope Ti6 brake and Hope/Mavic back wheel from the cannondale and swapped them onto the ECdM. Only change was going up to 203mm disc, but we now get a howling from the back brake that was never there on the ‘dale. Only when braking though, no problem freewheeling.
Have read via the Double Forte tandem forum that this is a common problem, seems to be a harmonic issue in Ventana rear triangles.
