I love these clip-ons. The only problem I have with them is, standard bar inserts, either screw in or rubber expansion bar end DO NOT FIT. The hole opening is smaller on the graves than all stock handle bars. I don't know if it's just graves that does this or other manufacture's do this. But I thought it was standard. Graves needs to offer bar ends for there clip-ons if there not gonna use a standard opening. Oh well. Besides that one rant, I'm very happy with my clip-ons.
