SHIMANO 200 GS REAR MECH DERAILLEUR VINTAGE OLD 7s SPEED RD-M200 LONG CAGE OLD | eBay
retrobikefranken - Shimano 200 GS brake lever MTB set
The large chainring looks oblong when it's spinning. Is this expected? It's a simple Shimano 200GS off a 90's Trek 820. The rings are not warped when viewed from above. : r/bikewrench
