Well, it's been a while since I've built a MA-2, but I have recently
built a few CR-18s, onto fixie hubs and they aren't bad. Not
particularly flat and rund outta the box and they seem rather 'soft'
while building but all in all, not a bad $40 or so rim with double
eyelets. Their width can make for some difficulty seating narrow tires
tho. Much easier with 28+ width tires.

you don't "need" double eyelets. it's jobstian myth and lore that they
provide any significant support.

look how thin that upper web is compared to the main rim bed.

btw, there's nothing particularly great about ma2's either. their low
profile makes them prone to flat-spotting. if you're looking for
alternative rims, and insisting on "traditional" but non-mavic, go with
something like ambrosio.
