You could be the proud owner of this vintage Sekai 400 road bicycle. Made in Japan in 1979. The Sekai company itself was a small family owned importer with Japanese roots and connections of Japanese goods and Sekai bikes and frames. It grew out of a store called Velocipede in Seattle which still exists and is owned by the same family. This lugged Tange steel road bicycle is ready for a new home. Comes with brand new Bontrager T-1 tires.


This bicycle is in good overall shape, with only minor scratches in the paint and some peeling of the decals but is free of major damage including bends and cracks.

This bike has been fully tuned by a shop mechanic with many years of experience. Then the bike was given a thorough inspection by the owner. Finally the owner rides the bicycle in every gear checking steering, braking, and shifting. After you receive this bicycle minimal adjustments and assembly will be needed to be ready to ride.

This bike is being sold as is, please see photographs for details.
