Hi all, 

I had to replace the tires of my TC due to a piece off glas in the front tire within 1000km. 

I ordered pirelli angel city in original front wheel size and 120/70-17 rear tire (It does fit) 

Now it came clear that al sizes of these pirelli's are front/rear tires! 

So when you order the 110/70-17 front tire it is also a rear tire, just depends on the rotation marked on the side. 

Good luck changing the tires, it becomes a complete other (better) bike 🙂
