i just happen to be holding a set of naked 26mm origin8 bullhorns in my hands that i am about to put on in place of my rb-002s. i am sure everybody will think i am crazy & i really wanted to like the nittos, but they are just too short.
anyway, be careful hj.paul7...
using an admittedly low-rent analog micrometer i just got 16mm for inside diameter of the o8s
