• So I've got a chance to get CK r45 disc hubs on dt swiss RR 411 disc rims.
    The rims are 18mm internal width and I'll be using them mostly on my road bike as sort of lightweight pseudo climbing wheels.

    I'm wondering about putting wider tyres on them to use on light mixed terrain rides on another bike. Would 38c-42ish be alright on the an 18mm rim?
