Shimano 6/7/8 Speed 10T Upper/Lower Derailleur Tension & Guide Pulley Set Assembly.
These will work with most 6 to 8 speed Shimano Derailleurs that use a ten tooth pulleys. Count one of your existing pulleys. Most later Shimano derailleurs use an 11T pulley and this item would not fit those derailleurs. Most early 6-8 speed ones use 10 tooth pulleys.
