My wife wants to get back into cycling after a few years off the bike. She's 5'5". I am looking for a good bike for her. I don't want to break the bank, but i want something with Ultegra SL/Rival level components. I've got a builder that will build me a custom Ti frame around Rival and Bonty wheels for ~3000. Any ideas as to what stock stuff is out there? I'd also like to get something light but also comfortable. Thanks for the help.
