Z Rims

Lawrie:
I sit here, pondering the mysteries of Z-Rims and suddenly my brain has an idea, which doesn't happen too often.

As Z-Rims aren't a very rigid rim, would they act as a sort of suspension by flexing on landings, thereby taking some of the shock out of the hit? I don't suppose they'd make that much difference but I thought that at least some of the shock would be dissipated in the flex of the rim instead of being transmitted to the frame.

And another thing, after a big flex, surely the rim wouldn't return to perfect shape? I bought a set NOS and the back rim has a pretty bad buckle in it, so i'm sure after use they would never be perfect again.

ORB:
storage is a bugger for twisting them

Lace em up, get em trued and they will be mint

Jazzchimp:
Has anyone ever flexed z-rims cos I always thought they felt stiffer than traditional rims. As for the famous Z-rim advert how does it 'ping' back to shape when the spokes don't flex. Think they must have had Paul Zennon on that one!!

They look great though!

theRuler:
a friend of mine had z-rims, and we used bend the back wheel double by flicking the back end out.
the same with the front, but by doing cowboys.
they do return to normal, but if you bend them too much, the spokes bend and hold the rim in it's buckled form.

acorn magnums were also really bendy.

get alloy rims and learn to land smoother!!!

retrorider.u.k:
z rims are shite ! in fact most of the acs stuff was rank  ;)
