SRAM Derailleur Sprockets: 3D Models and STL Files

This collection gathers STL files for SRAM derailleur sprockets and related drivetrain parts. You will find pulley wheels, chain gap tools, guards, covers, and adapters for bike repairs and experiments. It helps you locate a model for the part you want to recreate or modify on a 3D printer. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

How this collection is put together

Polyzon assembles this collection from search results on the connected platforms. Repeats and models without a preview are removed, weak matches go to the end, and the rest keeps the search order. Models belong to their authors — check the terms on each model's page.

«SRAM Derailleur Sprockets: 3D Models and STL Files»

The models range from small pulley wheels and sprockets to larger guards, covers, and adjustment tools. Some pieces are simple rotating parts, while others are brackets or spacers that hold or protect drivetrain components. Toy gears and fidget items also appear, and they differ from repair parts in size, tolerances, and how they are assembled.

Before printing, read the author’s page for the intended scale, the number of separate pieces, and whether supports are needed. Check the listed material and slicer settings, because small sprockets and pulleys often need different layer heights or infill than larger covers. Look at photos of real prints to judge surface finish and how the part sits on the bike.

To narrow the results, try related terms such as derailleur pulley, jockey wheel, chain guide, cassette sprocket, or drivetrain adapter. You can also search for the type of repair or upgrade you have in mind, like chain gap adjustment, derailleur protection, or brake piston spacing. Combining a part name with a bike style or drivetrain layout usually brings more relevant models.

FAQ

Frequently asked questions

What is a derailleur sprocket in this context?
It usually refers to the small toothed pulley wheel that guides the chain at the rear derailleur, though the term can also cover other sprockets in the drivetrain. Models may represent a single pulley or a set of related parts.
Can I use these models to replace a broken SRAM part?
The collection contains files that resemble SRAM-style parts, but you should compare dimensions and mounting details on the author’s page with your own component. The final decision depends on your printer, material, and the loads the part will see.
What should I check before printing a pulley or sprocket?
Check tooth profile, bore diameter, width, and any bearing or bushing recess shown in the model. Also review the author’s recommended material and print orientation.
How do I find chain gap tools or derailleur guards?
Search for chain gap adjustment, derailleur alignment, or derailleur guard, and add the drivetrain type if you know it. Related terms like jockey wheel and pulley wheel can also lead to useful files.
