Ok, so I had been riding on borrowed cheapo factory built 36 spoke 622x19mm (Matrix 750 on HB/FH-RM40 hubs; 700x28c tires) with on a bike that was temporary until I get my old one back from the dead.

Well the old bike really can't handle that rim/tire size, so I've had to examine my options of two other wheelsets to choose from both 32: CXP22 on cheapo HB-2200 and kind of old but not ridden much Velocity Aerohead on HB-6500.

Thinking I should hold of on the Velocity wheels until I'm a bit smaller less. . lets say I'm at 240 now.

Don't think I understand what the problem was with the 36-spoke wheels: the rim size, or the tire size? The CXP22 and the Velocity Aerohead are similar in size to the 36-spoke wheels, so if the rim is the problem you're going to be out of luck either way. If the tire is the problem, then you can swap it out and any of the wheels might work.

In terms of the two choices you present, the CXP22 is the stronger rim while the Ultegra HB-6500 is the better hub. At 240lbs, you'd probably be fine on either wheelset if they're well built. If you're in doubt, use the CXP22 wheel, but keep a close eye on the bottom-of-the-bucket HB2200 hub.

Rim width. Less than 28c just didn't work.
