SUNRACE cassette 12S 10-44T XD

Sunrace 12-Speed ULT XD Cassette 10-44T

The Sunrace ULT cassette features a hybrid architecture optimized for Gravel and Allroad 1x configurations. High-strength steel is used for the primary cogs to ensure resistance against abrasion, while the largest cog and spider are machined from 7075-T6 aluminum to maintain a total weight of 272 grams. This construction addresses the need for reduced unsprung mass without compromising drivetrain longevity.

The 10-44T gear progression offers a versatile range, maintaining optimal chain line and fluid shifting under load during technical climbs or fast descents.

Key Points

12-speed architecture optimized for XD and XDR standards. Bi-material construction combining hardened steel and 7075-T6 aluminum. High-precision CNC machining for consistent indexing. Verified weight of 272g for a superior strength-to-weight ratio. Silver finish for easier wear inspection.

Compatibility

This cassette is designed for SRAM XD driver bodies. It is also compatible with XDR drivers using a 1.85mm spacer. The tooth profile is optimized for SRAM (Eagle/Road) and Shimano 12-speed chains.

For optimal performance, we recommend verifying derailleur tension during installation for the 10-44T range. Technical support is available for specific configuration inquiries.
