I went for a wildcard, Light Bicycle 29er all mountain Carbon rims on their Novatec hubs. These hubs are NOT light, 400g + for the rear, about 200g for the front, but they have a steel freehub body that should be more durable than the alloy equivalent (i can save 70g with an alloy version) a steel axle for strength and the weight saving is in the important place, the rims.
They are the same weight as crests, but 23mm wide internally, so running a lightweight 2.25 on it gives a lovely tyre profile and sidewall support. They are pretty quick to get up to speed and strong in the hub, while being as stiff laterally as you could want. They also feel less harsh than similar alu rims, but I dont know why and cant quantify it, so its likely “new wheels syndrome”. Way stiffer than my crest 29er rims, I’m not small so they were a little twangy. The carbon rims are responsive, stiff and as a bonus, look stealthy and subtly bling… 770g front, 980 rear. Could easily drop 250g with some lighter hubs, but I’m going to run the novatecs till they die. Or I get a rush of blood to the head and buy DT240s.
Anyone know of a good reliable light 12×142 rear hub? Those A2Z only seem to have the light ones in QR flavour…
