I can't find a weight for the 14/15 version of the AC Sprint 350. I've read anywhere from 1270-1360g with the CX-Rays. That's a fairly big spread when trying to compare them against others.

add about 2g per spoke IMHO... dunno what the spoke count on those wheels are.. i think its 32 rear and 28 front... so figure at least 100g extra

IMHO skip those wheels... u'd have more joy on nio27s on WI hubs w/ cx-rays... better quality, more aero and around 1400g depending on the spoke count u end up settling on... functionally i think its the best all-rounder out there...

350 per rim, rear hub 205, front hub 58, the rest of the numbers comes from a spoke calculator, use 5.37g per spoke to get in the ball park. just a WAG +/-100g

The most recent AC350 rims that I weighed was 365g, 14/15's usually weigh around 6.5g with a alloy nipple, front hub is 58g and rear is 205g. That puts the weight at 1383g but I would say that could be +/- 15g either way.

Was it you looking for the sub-1400 gram wheelset a few days ago? Man, doing your research! good!
You can always test the 350s out before you buy them through us. I, personally, think they're a great crit and climbing wheel thats pretty under rated. I think we also have a previously rented set in our used marketplace. 24-32 laced, I think, but I'd have to check.
