Hey yall, I just got a sweet set of oversized (31.7 clamp diameter) Deda bars and want to put 'em on my ride. Of course I have a threaded headset and the only stems that fit these bars are threadless. I am planning on buying the adapter and a new stem but I was wondering first of all how do I find my steerer size? I think its 1 inch but I'm not sure if I'm even mesuring the right thing. Will a 1 1/8th inch stem fit a 1 inch adapter at all? Also my crappy wrenches dont even get "big" enough to remove my headset. What kind of wrenches (inexpensive a +) should I be getting? Thanks peops for any help.
