Grooved discs rotation - which way?

[Damoegan]

Right before I fit my new discs I've got a quick question.

Which war should they rotate? I thought they should go clockwise (from the pic bellow) but I seen a advertisment for black dimond discs and it said the rotation should go anti clockwise (from the pic bellow).

What way is right??

Anyone?

grooves on this style would normally lean backwards. that picture shows the same handed disk tho both sides so one of them will lean fwds = wrong

the top left disk in that picture would go onto the left wheel

The pic is one front and one rear dics of the same side mate.
So what way should they rotate from that pic? Anti clockwise?

Pagid discs are meant to go 'out to in' as the wheel rotates

So would that be clockwise from the pic then mark?

Yup

Though they did have a sticker on one of them confirming this

Most will sweep the dust outwards so as first said, leaning backwards. I'd fit them like this unless stated otherwise. Other thing to look at is if there are directional vents in the centre of the disk.

Fitting instructions on Galfer grooved discs gave the option of fitting them 'aggressive' or 'Passive'.

I've fitted my 341mm grooved discs aggressive since the ventilation slots in the disc weren't oriented in any direction. No sign of any build up of dust in the grooves.
