I just installed these and they look nice! This is the first bling item that I have owned on a bike so I feel like I need to get them dirty soon. I like the fact that it has an adaptor where the pedals screw in where you can run either 170/175 & 172.5. They came with 40/27 chainrings but I am old so I replaced with 32/22 for a hilly race this weekend.
I hope to ride tomorrow to break them in. I still need to install my KMC chain.
