Would you mind sharing the link? Thanks.
Well I live in Norway where everything is more expensive than other countries full price $28 and I got 25% discount since I'm a member of their "club" so I doubt it is for any help to you.
I guess most webshops has this type of membership clubs so they can trick you into buy more than you really needs but this time I needed new pads.

Outbound lighting portal downhill package, Quad lock and all the accessories, and crank bros stamp 7 pedals. I picked it up Monday, so we are in the process of dressing her up a bit.
Have you ridden with the portal yet? I have the overhang and trying to decide if it’s worth the upgrade. Getting the lights over to the UK is a bit of a pain.

Going to give these a try, make my own mind up. Both Radial’s, I did check!

Ref the radial tyres:
They make a point that the new tyres have a bigger contact patch for the same tyre pressure.

But the area of contact patch x psi for each tyre adds up to the weight of the bike (or bike + rider if measured with the rider sat on it). So how can the same bike and rider with the same psi in each tyre have a larger contact patch?

Obviously, the tread pattern and the softness or otherwise of the ground it's sat on will make a large difference to the contact patch. If the tread pattern was the same and the ground was flat and hard, then I still don't see how you would get a larger contact patch radial vs normal. Even if the radial tyre wall was more compliant, the weight of the bike + rider would be shared over two tyres, each one pressing every square inch in contact with the ground at 20 pounds per square inch (for example).

If the radial tyre wall was more compliant (so they say), then the bike would feel as though it was on softer tyres. In response I would increase the tyre pressure to reduce the contact patch to one that felt right. Maybe that is all they mean. You can ride with a higher tyre pressure to get the same ride feel?
