This is my '07 Marin Larkspur.

Original parts: frame, headset, handlebars.

What a fun project it was to upgrade the rest. I never imagined I'd be able to install a BB or an FD. I'm surprised how easily all the parts went together. It's now quite a nice ride. I'm grateful to all the info I got on these forums. It's that which gave me the courage to begin the upgrade project and do it all myself.
