I own an early 1990s road bike with Shimano 105 (7 speed) components.
I'd like to upgrade some of the components (lighter wheels, 9 speeds).
What components will I need to fully upgrade the bike to 9 speed
Ultegra specs? Is it even possible to upgrade a 7 speed to 9 speed
specs?
Thanks in advance--
