I picked this bike up on the side of the road yesterday. I’ve become the bike saver! I’d much rather see this bike being ridden by someone rather than being flattened at the tip.
Geo ain’t too bad!
Fancy lugs and headbadge.
Shimano Thunderbird II!
Oxford stamped saddle.
Shimano Positron! Check the cabling, 2 cables feed all the way from the shifter to the derailleur. One cable for up, one for down. Unusual! Best thing is it’s perfectly in tune!!!
After some research I’ve found out that it’s most likely a Japanese bike, brought over then assembled in Australia. The date of manufacture is stamped in the rear stays as June 1977 and the Shimano Positron gear dates back to 1975. It’s pretty special gear as it’s Shimano’s first mass manufactured “index” gearing. That’s SIS today, clicking into gears as opossed to old style friction gearing.
“The whole system represented a serious attempt to take indexing mainstream. The chain and freewheel were especially good. A heroic failure, but lots of the incidental details – shaped chain links, shaped teeth, incompressible cable outer – lived to become integral parts of SIS”.
A bit of elbow grease, a new chain, and she’s now ready for a new home.
