I’ve had all 3
Got for sale a bargain set of 240s wheels ;} on classifieds
240s and 350 are essentially the same, 240s are about 30grams lighter and the end caps are different on the front, the 240s being easier to pull on and off.. Need a socket to install the 350 caps which is mildly annoying, other than that I can’t physically see any difference other than the decals
They are both lighter than pro4
Hope pro4 are louder and have had them crack around the spoke holes in the hub, my mates also had a lot of problems with the freehub pawls but more than likely down to lack of maintenance… With dt it’s just fit and forget imo and the sealings far superior
I’d have dt all day long if I had the choice, I’d have the 350 over the pro4…
