1980s UNIVEGA with Tange bottom bracket Shimano 68/116 ,52. FB Spindle

Cold weather riding (Central Texas 50s) gave a fleeting klunk like spoken tunk like sound when climbing hills - Checked rear wheel alinement, seat, seat post, wheel, spokes, crank and freewheel, derailleur pulleys, then gave the bike a very good detailing (sometimes just a good cleaning can eliminate a strange sound) - Great no klunk tunk sounds - Then a few rides latter a faint return... OK - Now for the bottom bracket... These erosion's are more shallow then they look in the picture - Sure hope this is it but I won't know till I replace the spindle - We'll see...



Oddly the bearings and cups are in perfect shape even after examining with high magnification...
