24 spoke rear wheel - 2x both side, 2x + half radial, triplet?

I currently ride an HED C2 Belgium (23mm wide, 24mm deep) 24 spoke rear wheel. At 155 lbs, the wheel has been very solid and hasn't required any truing since the initial build (about 3000 miles ago).

I'm thinking of building a really light set of "race day only" clinchers around either a Kinlin XR-200 (19mm wide, 22mm deep) or a Kinlin XR-19W (20mm wide, 21mm deep). The 19W is a stiffer rim from what I've read and I think I'd be able to get away with a 24 spoke rear. Given the success I've had with 2x on both sides, I'm tempted to go that route, but am also intrigued by half radial and triplet lacing. All of the races I'm doing are uphill time trials, so they'll (mostly) see steady power output on good roads.

I've read a lot of good things about triplet, but only 8 NDS spokes sounds a bit iffy.

Feedback appreciated.

Thanks,
Bob

I do not think those hoops are really suitable for a rear wheel maybe someone will chime in about that better, but I do have an Easton EA90 SLX that is spoked that way and its a nice wheel 24 spoke 2x DS and radial NDS.

If the hub is drilled 16/8, ok.

I would use at least a 27/30mm+ rim.

I can get the hub in either 16:8 or 12:12.

Thanks,
Bob

If you want a good solid wheel, a straight forward 2x pattern R+L will serve you very well. OTOH- if you want something cool and trendy go ahead and build a triplet + radial. Either will serve well if built well.

BTW- another consideration is who you ride or race with. In my old circle, no one cares about how you ride if you're riding plain vanilla, but the fancier your equipment, the more likely you are to get some ribbing if you can't keep up.

Of course, those who are always off the front can ride anything they want even if it's odd, retro, or uncool, since no one criticizes folks who ride faster than they do.

I recently built up a set for myself - 20/24 spokes using Kinlin XR-300 rims. I did the rear 2x + half radial. I'm really happy with the set so far, I've beat up on them already and they seem completely solid. The XR-300 is a heavier rim at 495g on my scale, but even using a heavy (370g) Shimano rear hub the set still comes in at 1696g.

If you did that same build with XR-200s and a ~250g rear hub you'd be looking at a sub-1400g set that should still be strong enough. Or go with an XR-270 in the rear for a little insurance. (BTW I weigh 135lb.)

The OP is only doing time trials so, unless he is really slow, no one will be near him to make any derogatory (or complimentary) comments.

Thanks for the input. Forgot to add that my current 24h rear is laced 2x on both sides, so I'm partial to that since it has been very reliable. The XR19w is center drilled and has eyelets, so triplet would be pretty "easy" to do. With triplet, I've seen both 3x DS + 1x NDS and 3x DS + Radial NDS. Any reason to prefer radial over 1x?

HillRider: Your comment encourages me to ride faster so I can pass people and tell them to check out my sweet lacing pattern.

Bob
