Determining nipple length for DT Swiss RR465

I am wanting to build my first set of wheels. I think I am going to go with Ultegra hubs and DT Swiss RR465 700c rims. After doing research on the internet I am not finding any info on which size nipples to order. Does anyone have any recommendations for this combo?

size is by what the end of the spoke is. 14 or 15 gage.
since thread is rolled around the wire, it's smaller in 15 ga.

Yea, I got that part. I was talking about the total length. I want to use DT 2.0/1.8 Competition Spokes. The DT Swiss spoke calculator has 12, 14, and 16 mm long 2.0 nipples. I am unsure which size is right for these rims, am I correct in thinking 12mm are the right ones?

If you use 12mm or 14mm with boxed spokes, use an ERD that aims for the screwdriver flat of the nipple when calculating spoke length.

If you use 16mm with boxed spokes (which I don't really like) use an ERD that aims 1-1.5mm below the screwdriver flat of the nipple.

...else you run the risk of running out of threads before proper tension has been achieved.

10mm nipples if usable with this rim give you a lot more overhead - aim somewhere between the flat and top in that case.

For 16mm nipples, its a lot easier if you hit an LBS with a Phil Wood spoke machine...assuming they know how to do the 12mm threading operation they can eliminate the need to short the spokes with 16mm nipples.

if it's your first build use the standard sized nipples that come with the spokes. it won't lead you wrong.

Do you understand:

1. The effect nipple sizes in general have on "effective rim diameter"?
2. The effect factory boxed threaded versus manual spoke machine threaded spokes have upon "effective rim diameter"?

If you dance around the DT site you can find the nipple length. It is 12mm. You find it by using their spoke calc.

yes, do you understand that if you use the DT Swiss spoke calculator you can input the nipple size and it will calculate accordingly?

Are you aware that the DT calculator has not been the most reliable - hence why many folks use SpokeCalc, or my own and other online caluculators?

Are you sure they correct for nipple sizes?


(Hint: There's a reason I paid 'em a visit at Interbike....)

how about i ask some questions? Are you aware that this is the OP's FIRST WHEELBUILD? do you think someone who has never built wheels understands "For 16mm nipples, its a lot easier if you hit an LBS with a Phil Wood spoke machine...assuming they know how to do the 12mm threading operation they can eliminate the need to short the spokes with 16mm nipples.
"?

I built a new rear wheel for myself last fall. I used the RR 465 rim, DT 240 S hub, DT 2.0-1.8-2.0 spokes on the drive side and DT Revolution 2.0-1.5-2.0 spokes on the non-drive side. Used 12 mm aluminum alloy nipples (black). The DT calculator gave me the correct lengths. Really like the wheel.
