Plastic Bicycle Chainring Guard — Five Models

A plastic bicycle chainring cover offered in five supplier model shapes. Choose the model that matches your existing guard and fixing arrangement; each option has its own original supplier-labelled diagram.

Available models

• G4QA48
• G4RB42 1
• G4RB44
• G4RB48 B
• G4XD 48

The model names follow the linked supplier options. They are not a verified promise of chainring tooth-count or bicycle-brand compatibility.

Check the diagram

Compare the complete outline, fixing tabs and the marked reference lines with the guard being replaced. The diagrams label different line measurements for different models; those markings are not presented here as a verified bolt-circle diameter.

The supplier's general written size does not reliably distinguish all five models. A full crankset compatibility list and fitting-hardware specification are not supplied, so confirm the required fit before ordering.

One selected plastic guard is supplied. Crankset, chainring and bicycle are not included; fixing screws are not confirmed as included. Fit according to your component manufacturer's instructions and check clearance from the chain and moving parts.
