Any preference between 6-bolt and center lock rotor for polo? Is one better than the other in terms of robustness, weight, set up?
I read somewhere 6-bolt is better because it doesn’t require a cassette lockring tool and big wrench.
What about the unused disc mount on the rear hub? Is 6-bolt or CL better or worse for polo in terms of weight or getting damaged being on the bike without a rotor mounted?
