On my new road bike, I had to use centerlock adapters, because fun. I grabbed some generic taiwan/American Classic ones that fit 15/20mm external BB type lockrings. I thought everything was good ( a little play when rocking back and forth, but hey) but that turns out not to be the case- my front adapter lockring was rubbing on my fork. I need to switch to either a centerlock rotor, which MIGHT work (it works for a shimano rotor) or a new adapter. Luckily, I found a shimano lockring in my box-o-parts, but unfortunately it's a bit smaller than the other one.
Long story short- how dead am I if I run this lockring on my front rotor:
Front-
Rear-
I am slightly concerned as the smaller lockring doesn't cover the same amount of rotor as the original, however it does cover the bottom of the tabs so everything is locked in place. I figure with the alloy carrier, good contact with the tabs, and only slightly reduced coverage, I should be OK. I probably trust this setup more than a weird chinese ASHIMA adapter, which may be the second choice....or a shimano RTAD10, if I can find one.
