I have some dt swiss tk series built with 32 spokes that has several thousand miles on had to be trued once. What really impressed me about these rims. When the rd and a stick broke several spokes spokes on the drive side it was still rideable. Eventually I wore out the braking surface on the rims before replacing with same rims. I have taken several curbs out and mtb trail with these wheels my mechanic has them on his mtb and his cross bike.
