Wrenching on bikes for eight hours a day in 1987, we used to imagine what the future would hold for bikes. Every year, with Shimano's new releases, we didn't think it was possible for them to improve shifting. Yet somehow, the next year, year after year, they did. The owner of the shop, Bob, often wondered why the ancient chain hadn't yet given way to some kind of belt drive, with individual gears giving way to infinitely-variable drives. We did imagine electronic shifting--and I'm glad people enjoy it today--the dream of us kids back in the day.
