When I last talked with Gilbert Anderson more than five years ago he had just relocated his eclectic North Road Bicycle Imports from downtown Raleigh to Yanceyville and was just getting unpacked. When we dropped by his downtown Yanceyville shop Saturday he was … still getting unpacked. The reason wouldn’t surprise anyone who knows the affable Anderson: Distract him with his favorite topic — bikes, especially unusual ones — and he’ll stop what he’s doing and embark on a discourse that may bounce from internal hubs to belt drives to ultralight steel frames of the ‘70s, to why road racing was banned in England to the latest cycling sensation. All, seemingly, in the same breath.
