as above, should be okay if you are not too heavy.
I have recently gone for kinlin xr31 28h 28h for a rim brake cx / off-road build, seem fine. spoke pattern is also an important factor.
as a reference i have been riding 24h 24h disc wheels (hope / stans type) for ages, never a problem
Quick SSCX wheel question...
Should a 24h front 28h rear wheelset with Kinlin XR22 rims be ok for some off-road riding, mainly bridleway type stuff, and possibly the odd CX race?
