Bicycle Sprocket guard.To fit TY501 /48/38/28T
The mounting holes were off and didn’t fit like I thought it would.I did drill holes in the sprocket to make it fit. They are as close as I could find.Next time I will order the whole sprocket with guard.The cost is the same as just the 2 guards I ordered.

Incorrect size description
The chain ring that this guard was for measures 12 cm from one screw hole to another. The description for this guard says 12 cm. Even the pictures show that from one hole to another (not diagonal), it says 12. I opened up the package, and put it on my bike. I couldn’t secure it on the bike. The screw holes so not line up. I measure the guard itself, and the screw holes measure 13 cm apart. I double checked the chain ring on the bike. I returned it, and got a replacement. Even the replacement measured 13 cm.
