Bottom bracket confusion
I just bought a frame off Ebay. The frame is a Rocky Mountain Solo 50ac. The frame is bare it doesn't come with anything on it. I want to build it up with pretty nice components. I decided to start with the bottom bracket. Bottom brackets seem very confusing to me. Can anyone tell me which one I need. I think it is a 68mm english thread. Will a gxp or bb30 work or am I totally off track? I have no idea what the different types are. Thanks.
