deep v radial truing

seems to be a 1mm flat spot on my deeps Vs local to the join.
doesnt want to go away even though i have releived quite a bit of tension. either side of the joint.
anybody else noticed/have this problem?

Not uncommon, especially with pinned rims like velocities. For that matter I’ve never had a Mavic rim that didn’t have a small flat spot or hump at the join. If a rim is out of radial true by a mil or two you won’t feel it with a tyre on, but you’ll drive yourself barking trying to iron it out. Just put a tyre on and ride.

thats reasuring advice, iv’e got some 35s on and you really don’t notice anything, but that woudn’t stop me going crazy trying. thanks
