I'm having a surprisingly hard time finding a definitive answer on this (maybe that's a sign of a definitive "No"), but is it possible to buy handlebar grips that fit a road bike sized handlebar?

Everything I see for grips is made for 7/8" bars, but I am a newb and bought (and already put on) 15/16" road bars even though I planned on adding grips all along. Is it possible to just slide on 7/8" grips over the 15/16" bars if I can't find any for sale?

Thanks.
