I'm still in the planning stage of a new wheelset. Is there a reason to stick with 32h hubs on carbon rims these days?

Im 95% sure I'll go 28 up front and 75% sure ill do 32 rear, but am open to suggestions. I'm interested in Berd spokes (they're local) and each spoke is like 8 bucks, so fewer is cheaper.

I'm 195ish with a damn near Rivendell saddle to bar drop. My left leg is considerably stronger than my right (zombie cartilage situation) which puts weird torque out back.

I've never had a problem with spokes other than wearing them out mountain biking - they seem to like to give way at the J-bend.

32 has a lot going for it, but mostly redundancy.  And its nice if I do break a spoke I can hardly tell with 32h.  Less than that and the wobble gets big.  Crashes do happen.  Fewer spokes to check with truing a 28H wheel.  ;-)  Cheaper and lighter with 28H too (not that I would need to save a couple of bucks on a carbon build though).  No real reason not to do 32 unless weight and Aero are a big deal.   I guess I could go either way...

Chas you're supposed to tell me what to do, not just agree that there's no right or wrong decision.  This isn't your first time on the internet.

While you did specify your weight, you didn't specify how aggressively you ride and what the roads or trails you'll be on are like. If you tend to be rough on wheels, 32 spokes may buy you some extra durability, but the rims probably make more difference in that regard. I'm not a big fan of carbon rims for rough use, mainly due to the replacement cost if you screw up and damage one, but that's a risk that you have to assess for yourself. I do have one set of carbon wheels that came on a bike, but I only use them for dirt road events that I know aren't particularly boney. I use aluminum for riding trails and dirt/gravel roads I don't know well.

Regarding different spoke counts for front and rear, I've built several sets of wheels that way and there aren't any issues with it per se. If you build and maintain your own wheels and you're using expensive or hard-to-find rims, it can advantageous to only need to keep a single spare rim on-hand for quick repairs, which is one advantage of the same spoke count at both ends. If you rely on some else for repairs, the spoke count probably doesn't make much difference.

Having worked with Specta/Dyneema, Kevlar and Vectran in another industry, I'm not convinced that fiber spokes are a good idea at all, especially off-road. They seem like an expensive problem waiting for a really inconvenient place to happen. The idea of spending $500 on spokes alone seems insane to me, as I can build two complete sets of nice wheels with alloy rims for that price. But hey, it's not my money. [wink]

I'm a fan of run what ya brung one bike type riding, so I use my gravel bike at events that sometimes include single track or ATV trails and also curb hopping commuting. The only time I've broken a rim it was a WTB aluminum frequency team rim that they used too soft of an aluminum on and it developed a bunch of cracks. I'm way harder on hubs.

Interesting viewpoint on the spokes. They SEEM good, but most of the 'reviews' are really just press releases.

It might all be a moot point though. White Industries is warrantying my hub shell and if that fixes my wobble issue I might keep my current setup.

Not that anyone asked, but spending $8 per spoke seems a bit crazy, especially given that it is a pretty new technology - has not been time-tested.

DT Competitions are a little over a buck apiece, and are bombproof. Hell, you can get some pretty fancy Sapim spokes for a couple bucks apiece, and they are also very well-regarded.

$8 a spoke is a bargain compared to Mavic R-SYS Carbon Fiber Spokes which were $20 each and you had to buy 4 minimum...

What's the wheel size?  Shorter spokes and closer together at the rim on 650b makes 28h effectively "same" as 32h on a bigger wheel.  

Not saying this would be appropriate for everyone, but I'm right about 200 lbs. and spent this gravel season on a 24/24h wheel set, both wheels built 2:1.  16 spokes on one side, 8 on the other.  This works because of how good some modern rims are, but would be a disaster on other rims.  I've done some test builds to confirm this.

I think a big factor is always that some people are just harder on stuff than others.

700c. I'm not going to make the switch to 650b until studded tires come out in that size. Minnesota problems.

I agree with you on rim quality improving. I can't imagine considering less than 32 on my old WTB aluminum rims that were as stiff as soggy spaghetti.
