I am thinking about using my K2 zed comp for my build to save money and ultimately use a better quality bike than if I went to walmart and bought one. I can only find one instance of someone using a k2 on the site. Anyone have any thoughts? I am worried the frame might be too small. Its a 26in with a medium frame. I think It would be a pretty quality bike to use for my build, and it would allow me to go off the beaten path a little bit.
