Can anyone recommend me a good strong light wheelset for city-ridden disc MTB?

factory built wheels are the best buy because being made in a machine that tightens and trues the wheel at the same time is far more precise and less expensive,hand builds aren't worth the money or the hle,you'll be forever getting into them with a spoke key,i have a road ready muddy fox with mavic crossride disc wheels,adjustable bearings and 24 bladed spokes front and rear,they are between �160 and �190 a pair,they'er very good,just what your needing
