Re:
Raul Alcala and Sean Kelly in the 1990 Tour of Switzerland. Alcala is on a steel bike, Kelly is on a carbon TVT, the rear brake cable exiting the frame is the giveaway, along with the band on front deraileur and carbon forks. The head tube is one piece - not like the 89 bikes.
Sorry messed that one up, this is Kelly sitting on a TVT bike at the 1990 tour, you can see the distinctive TVT seat cluster clearly. It is just painted black not shiny aluminium as you would see on most TVT frames
