DT does make some nice rims. They build up straight and round. Velocity does also. Velocity doesn't have any rims with ferruls, so they aren't as sexy as DT, but they do offer offset rims and those buildup with heavy riders well. Those are my two favorite brands to build. Fir was making a comeback and I built some tandem and clydesdale rims for a few bikes. But I can't find a supplier for them anymore. I never did like to actually build with Mavic rims. Although they had some real pretty rims and the ceramic sidewall rims do work good for braking quality. Their aluminum alloy was just too brittle and cracked too easily. As for their ceramic sidewall rims, I don't like the sound of braking hard on aluminum rims when you get junk in the brake pads. I only build Sun rims on mountain bikes. I find their rim diameters too small for road bike tires.
