I'm riding a 24''. Currently I'm using a DM24 for the rear, and I find it quite narrow. (My 4-bolt mounts are spaced too wide too) I'm stuck on which rim to get, either a DX32 (plenty in my country ) or some trials-specific 46mm rim, like the viz rim. I ride more of street than trials, and so I wonder if a 46mm rim would too wide? DX32 is just 39mm, and I reckon that width is quite good. I don't really mind the width, but I would like to hear your opinions.
