Vintage tandem wheelset, 27" rims for 27 x 1/4" tires, 48 spokes front and rear, Wienmann concave rims, 100mm front 140mm rear steel shelled Phil Wood hubs. Custom wheels off of a 1980s Kuwahara Adventurer T.K. Please note that the rear spacing is wider than you would find on any non-tandem bike from the early 1980s. I am putting up this ad in case someone has a vintage tandem and needs replacement wheels. Located in Chevy Chase, DC.
