I bought a 12.9 Revo and it came in slightly under 12.7. Has anyone else had this problem?
Predator Revo Shaft

Sounds strange, as these shafts aren`t turned down like regular shaft, but rather being molded. So there really is no way you can get a 12.7mm shaft, unless you have gotten some sort of prototype. Right now Predator only makes the Revo in 12.9mm and 12.4mm
Are you sure your calipers are correct?
This is incorrect. They use something shaped like the foam core as a mold and lay fiber (likely pre-impregnated with epoxy) over it in different directions and layers. The final product may or may not be baked in a pressurized oven upon completion. After they put some kind of finish layer on it and likely do spin it to smooth the final coating.

Yes so they are molded. It`s alternate layers of graphite sheets and epoxy over a foam core, then baked in an autoclave under vacuum to set the epoxy.
The might spin the shafts afterwards to add some sort of coating, but the shafts aren`t turned down like a maple shaft. So the mold spits out the same shaft over and over, and a 0.3mm shrinkage seems highly unlikely.
The Revos I have....
12.9...measures 12.9 about 1" from top of tip and increases above 13.mm when moving away from tip toward end of shaft.
12.4 ....measures 12.4 about 1" from tip and increases above 13.mm when moving away from tip.
The Revo's are advertised as....REVO Low-rise taper with 8% rise over the first 14 inches
12.9...measures 12.9 about 1" from top of tip and increases above 13.mm when moving away from tip toward end of shaft.
12.4 ....measures 12.4 about 1" from tip and increases above 13.mm when moving away from tip.

That is definitely strange as I've had 2 Revos before they released the shafts as a stand alone purchase and both measured 12.9 at the tip and then it was gradually thicker as I moved towards the middle section of the shaft.
Makes no sense.
Are you 100% sure your caliber was set on zero before you measured?
Mine is exactly 12.9. Love that thing by the way.
The 12.9 is 5% rise over the first 14 inches.
The 12.4 is 8% rise over the first 14 inches.
Yes, lol of course the shafts are going to go over 13 mm as you move away from the tip......lol
Every shaft does that.
Never seen one that had a joint that was under 13mm for example.
Both of mine are 12.4 at the tip.
OK..so I'm a knucklehead....forgot the word rapidly INCREASES. Definitely not a pro taper. The measurement seems to be accurate at the tip.

Just curious if you like the shaft or not and if you have any thoughts on it? Thanks!
I have both the 12.9 and 12.4mm Revo shafts. They both measure exactly what they're supposed to.

Do you have a preference... I'm sure you enjoy good success with either.
Frank...I like the 12.4 better, although I can play equally well with either size shaft.

Is the deflection the same? What shaft did you play with before you played with the revo? What tip are you using? Thanks!
So, this is the replacement shaft:
I notice there is a light mark underneath the number '0'. Which looks more apparent at certain angles. Does this look right?

If you are still not happy/OK with the replacement I would just send it back, get a refund & then order from another authorized dealer - this is if you really want this shaft.
Seems like you keep getting used shafts. I recommend ordering from Seyberts, bought both of mine from there, fast shipping & flawless
