I'm sorry if this topic has been discussed before. I searched and read through three pages of threads and couldn't find what I was looking for. I have some brand new 10 speed zipps for my DA 10 bike, but I was wondering if I could put those 10 speed wheels on my Ultegra 9 speed bike. I tried putting them on and it seems like the 9 speed chain is not too wide but I was just wondering before I go ride it. Thanks for the help.
