Through my family I have just had a Cube Litening bike passed down to me. It seems to have frame. forks,stem,handlebars and seat tube in carbon fibre along with Shimano Ultegra gears and brakes and Fulcrum wheels. Apart from 'Litening' and 'Cube' there are no other markings on the bike to identify it.Does anyong know what it is likely to be and how old it might be. Thanks, Allen
