My BH Speedrom is a 53cm/ 21" frame that should fit most riders 5'1 -5'5". It is equipped with Shimano Ultegra components and has upgraded HED Bastogne wheels. It currently has a wide range derailleur fitted to it, but the originalinal tighter range Shimano Ultegra derailleur and cassette is included. I can also include the originally supplied Shimano R20 wheel set.
