Straight from Cleveland website! Question remains how many more are yet to come….

“Cleveland Golf has determined that, due to a variance in our manufacturing process, a limited number of HiBORE XL 10.5 degree drivers may not conform to the Characteristic Time test standard established by the USGA. It is only the right-handed HiBORE XL 10.5 degree model that is in question. All other right handed lofts (7.5, 8.5, 9.5, 11.5, 16) and all left-handed HiBORE XL drivers, as well as all other models, including the HiBORE, HiBORE XL Tour and W-Series HiBORE XL (For women), have been tested and are determined to conform to USGA standards.

Therefore, effective May 28, 2007, Cleveland Golf is implementing a voluntary product conformance test for the right handed Cleveland HiBORE XL 10.5 degree driver.”

Nike leads the way to disaster ??? :)

How weird that it’s only 10.5°, wonder why ?

Wasn’t there a school of thought that with current equipment 10.5 is actually a more optimal launch loft now? Perhaps that’s related.

Then again, I may have read that in Golf Digest, which the last time I was looking was suggesting a weird reverse pivot might be the key to swing nirvana…

Anything from 12* upwards doesn’t have to comply, in any brand. COR rating only applies to lofts under 12*. Jon…

Actually Callaway’s Big Bertha 460 13HT (13 degree driver) has been deemed non conforming also.

Try 15 degs lads

Sorry mate that 10.5 launch angle is OEM marketing people blowing hot air out of there ass. Optimal launch angle depends on swing speed.
