i dont think so, my friend have piranha with try all tyre and comparing to my bike ( ozonys xs 26 with der kaiser) i would say it wont fit. we didnt try, just compared so i am not 100% sure i have been using der kaiser for 10 mounths, and all i can say--> great tyre. so stycky compound that it wont slip ewen on wet, but yet it is so tought that is still 50% of the thread alive. sidewalls are wery strong and i didnt have so many snake bites since i started to use it. it is wery big tyre ( comparing to try all rear on the same rim echo urban, it looks like it is 2,8 wide). i think you cant go wrong with this tyre, only "bad" thing is that is heavy comparing to some other tyres ( schwalble) i hope i could help even a bit
