Here's what I can garner from the bike. 27" x 1-1/4" tires, Shimano Altus LT shifter and deraileurs (front and rear), Shimano "Selecta" cranks, Shimano "DL" hubs maybe, frame is Araya 1435 tubes (so says the sticker anyway), unsure of the brake manufacturer, rims are Araya, can't find a serial number on the frame anywhere, seat post and handlebar neck have "SR" stamped on them. Then there's this little sticker at the bottom of the frame stating "Made exclusively in Japan for NIDA". What does that mean?
This bikes is a real pleasure to ride but it needs some cleanup work (regrease the bearing, repaint the frame, etc). Pictures are forthcoming. Was this bicycle of any real value when it was made? It's a GREAT bike now.
