Fortunately for me, Scott Mackey, the Owner of Pedal Play Bicycles in Baton Rouge, just happens to be a rider/collector of C&V racing bikes (which are hung up in his shop for all to admire when he's not out riding them). I know that if I need some wrenching done on my Ciocc that I'm not up for that Scott and his bunch can handle the job. I don't know about 27" tires, but Pedal Play sure has a fine selection of tubulars.
