I'm just a wee lightweight these days, but I'm using some homebuilt wheels for a non-standard application. I've got IRO rims and hubs (unbadged Velocity Fusion rim, as best I can tell) that I use for singlespeed CX racing and light MTB trail riding. I beat the snot out of these things and they're still in good shape. 32h rims laced 3-cross with 1.8mm straight gauge spokes.
I'm looking to lighten up for next season and thinking about building a pair of 24/28 race wheels. I'm not too worried about the structural integrity of them, even under the pounding they'll get.
