1" to 1 1/8" Threadless Stem - Do I Need a New Stem Top Cap?
Got a new stem coming from Velo Orange. It's 1 1/8". I'll be using the 1" to 1 1/8" stem shim Velo sells as my headset/fork size is 1" (Kilo TT).
My question is, since I'm switching from a 1" stem to 1 1/8" stem what size top cap should I be using? 1" or 1 1/8"?
