On Velocity Deep V rims, if you look on the tire/tube/rim tape side of the rim, the spoke holes are staggered to the left and right, but on the other side (i.e. hub side), they all emerge in the center (i.e. at the point of the "V"). Does this mean the holes are drilled at an angle so that a spoke hole on the right actually angles inward to the left (and thus that spoke should go to the left hub flange), or should the "usual" rule apply (i.e. holes on the right go to the right hub flange).
I recently built a wheel using a Deep V, and so far it has been great, but I used the "usual" rule (holes on right->flange on right). But I recently read about how some deep section rims are drilled the opposite way, so now I'm worried I did it backwards and may have reliability problems in the future due to the nipple not being seated properly.
Does anyone know which way the Deep V's are drilled?

Holes offset in the bead channel to the right but centered where they show up at the inside of the rim should go to the left flange. That way the spoke and nipple are more inline with the forces.
I'm afraid you did it backwards on the wheel you built up if your description is accurate.

Holly Crap! Didn't u notice the nipples were angled a certain way and u had to force it to meet with the spokes?
By your description, they are backwards.

Yeah, it was pretty dumb (and late that night). The nipples actually didn't seem like they were angling the wrong way, but rather just pointed straight down towards the center, though I'm sure it's putting extra stress on the spoke where it enters the nipple. Oh well, live and learn. I'll just redo the wheel, and probably replace the spokes to be safe.
Thanks for the confirmation.

When they are loose they probably will just hang from gravity. But pull on then from inside the rim and it should become clear very fast which way the spoke and nipple want to seat and go from there.
If they aren't bent near the threading I'd be happy re-using them myself. If they did bend or kink right at the first thread then that first thread is acting now as a nasty stress riser and I would not trust them to carry my own backside. Spin them in your fingers while watching the threaded portion. If they are straight then no harm done. If they wobble then junk 'em.
i just did exactly the same thing. i was following sb's wheel building guide and made the mistake of assuming that the key spoke was next to the valve hole - it's one hole away. so i rebuilt [with same spokes - but they weren't tensioned] late night/beer were to blame.

Imagine an arrow extending from the hub flange to the spoke holes near the middle of the rim. Such a path would exit the outside circumference on the opposite side. Your spokes should follow the arrow's path.

I actually laced a Velocity Deep V backwards this same way, rode on it for 1 week before figuring out what I'd done. I mistakenly assumed the sticker near the valve hole was on the same side on different rims. They weren't.
I corrected the problem and all is good a few thousand miles later.
