CXP-33 Rim

Anyone have any experience removing flat spots from the CXP-33 rims?
Have one with a single spoke 1.5mm dip which translates to about 56kg rather then 90kg so it should be bumped-out somehow...

If you have any experience with bumping-out the CXP-33 please advise... (28-hole rim)

Thanks

All other spokes are about 90kg but because of the slight dip, one spoke is about 56kg... We just tightened up another round and got the dip down to about .75mm which is o.k... But of course that single spoke is still about 56kg which is way loose... So we figure we'd try and bump out the dip using wooden blocks etc. but are not so sure how the CXP-33's will react to such...

I don't know what happened to my earlier post.
You're going to need to hammer the flat spot out from the inside using a rubber mallet and wooden blocks placed on either side of the flat spot.
This means removing several spokes and loosening the others. It may be easier just to rebuild the wheel.
