I have looked at them side by side and at the geometry details on the Specialized website. Can't see any differences, Enduro looks to have more going on with the tubes, hydroforming, etc.
This months MBR says they ride like different bikes, the pitch being far better. Why and how? Is it just down to the differences in the shocks; Enduro – own brand shock versus Pitch – Fox. Are the pivots in slightly different locations.
It doesn't sound like MBR tested them back to back and they don't really expand upon their comments other than to say the Pitch felt better.
Any views or ideas appreciated.

The main difference is weight.

I've tried both, and own the cheaper pitch pro, abet with a few mods to get it around the 30lbs mark.

The enduro I rode was an s-works, so I felt light, and fairly quick up the climbs, just as fast as my pitch on the way down.

Hope this helps.

The Enduro has a custom shock length.

The Pitch uses an off the shelf Fox Float and has a rocker link specifically designed for this.
