This is a vintage used Sekai 4000 Professional road bike.  This bicycle was hand made in Osaka Japan and features quality chromed lugwork and Tange Champion butted tubes with Shimano drop outs. Unfortunately all of the decals are missing with the exception of the Tange Champion decal.  The 4000 Professional was Sekai second tier offering, surpassed only by the 5000 Ultralight.  The bike is equipped with a full Shimano 600 group that dates from 1980 (see component specifics below for further information).  There are some scratches in the paint but no major dings or dents.  This bicycle has been professionally tuned  by one of our shops mechanics and once reassembled from shipping is ready to ride.
