It doesn't have interrupter levers. I think the biggest problem with those levers, whether with cantilevers or discs is that they are a possible source of cable friction if you don't get the cable routing right. I took them off of my CX race bike, along with switching to Ripcord housing, and the difference in performance, using Shimano CX70 cantilevers, is astounding (probably mostly the Ripcord though).
