Hi!
I've just gotten a very nice deal for a carbon spinnergy rev-x wheelset plus a 7800 Dura Ace groupset. I'm planning on putting everything on a frame I have.
But first move, first problem. I've struggled like a madman to put tires on the wheels. I found it nearly impossible. I made it for the front wheel with a used tire. But then, big mistake, I tried with a new tire on the back wheel. Doing that I've punctured the inner tube and can't take anything off now.
Are the rims diameter notabley bigger than normal? Or is it just me… Now I'm afraid i might damage the rim because of the forces i need to remove the tire. Might just cut it

Thanks!
