I've built several wheelsets now and have always used thicker drive side spokes (Sapim Race) and thinner non-drive/front spokes (Sapim Laser).

I'm thinking about doing a triplet rear lacing on a 24h Kinlin XC-279 hoop.

Since there are 16 DS spokes and 8 NDS spokes, should I continue the practice of thicker DS spokes? Would it better to reverse things and use Sapim race on the NDS/Laser on the NDS since those 8 NDS spokes will be doing a lot more 'work'?

Thanks,
Bob

Use Race on both sides. What hub is it?

Note that the XC279 rim is slightly offset drilled, which will result in some DS spokes being in the wrong holes. I don't think it will be a problem, but make sure the NDS spokes are in the right holes.

Thanks, rruff.

It'd be one of the BHS hubs...either the SL210 or SL190.

Hmm...I thought that the XC-279 was center-drilled. My first choice would be the XR19W since it is (I believe) center-drilled and has eyelets, but I think at 160 lbs, a 24h rear would be pushing it with that hoop.

The offset is only very slight on the XC279. I think it will work fine.

Lace the NDS 1x heads in.

Is there a particular reason you want to lace triplet?

Far be it from me to question Ron, but the vast majority of people who use this drilling lace it radial on the DS and 3x on the NDS. I agree that the off-set on the XC279 is very slight, and no one has yet mentioned it was a problem with the 16:8 (not so the Archetype, where the offset does cause some issues).

 

[rruff]

People are really lacing your hubs radial DS and 3x NDS?

With triplet lacing the tension will be fairly even left and right so you can use the spoke of your choice as they will all have decent tension.

I think that's backwards, no? 3x DS and radial NDS? I was planning on doing 3x DS and 1x NDS. As for why, I think it'd be fun to try and see what kind of wheel it yields.

Lateral *stiffness* is greatly influenced by the NDS bracing angle, and triplet removes half those spokes.

I had understood that it was standard practice to go radial-elbows out NDS on a triplet lacing - no? 3X DS works well because it is the same lacing as a traditional 32 spoke wheel. IMO that makes for a clean, easy, and symmetrical pattern.

Please correct me if my thinking is off, especially since I've never personally done a triplet build. I'd be curious to know how much it "actually" does equalize the DS/NDS tensions.

Lace the NDS 1x heads in.

The hub has a small diameter on NDS so the spokes will cross and contact each other at their thick end near the head. Which means they get bent heavily on a short lenght. I wouldn't be comfortable with that.
So I would go with radial if the flange can take it and heads out if the offset is big enough. The latter because it seems easier on the flange.

I did a triplet with a Shimano FH-6600 hub, all CXRay, 1x heads in. The flange diameter (45mm) was big enough for the spokes to cross at their flat parts so they didn't bent at all.

Spoke hole orientation:
I tried a triplet with a Kinlin XR-380 which has a slight orientation that is still too big for triplet.

You can do 1x on the NDS which will lessen the stress on the hub flange. DS lacing will not be the same as a 32h wheel, though there will be the same number of spokes.

The tension on the NDS will end up twice as high as it would be with conventional lacing.

The hub has a small diameter on NDS so the spokes will cross and contact each other at their thick end near the head.

It won't be *that* near... the spoke angle is 45 deg and there are only 8 of them. There are many here who have laced 1x on front hubs and the situation is much more extreme.
