1987 Miyata Competition 512

This is an old-school triathlon bike by Miyata (made in Japan), likely from 1987.

Everything on the bike―from the frame and fork, down to the brake pads and tires―was in great shape when I bought it, but it did need a thorough cleaning and a tune-up. It also has new bar tape.

Note that the front wheel is smaller than the rear, which was standard for triathlon bikes at the time.
