The SRAM PG-720 DH cassette embodies the pure philosophy of downhill: a 7-speed gravity-optimized drivetrain system designed to exploit every meter of negative elevation, lap after lap, without compromise. With its 224 grams only and its perfectly calibrated 11-25 tooth range, this cassette is an integral part of the SRAM 1x DH ecosystem and represents one of the most accessible and high-performance dedicated downhill cassettes on the market.

Technical Summary

This downhill-optimized cassette stands out with its 7-speed architecture that promotes ultra-fast transition from the starting sprocket to the top sprocket, enabling explosive accelerations out of turns or at the start of a run. The 11-13-15-17-19-22-25 range offers balanced gear jumps that give tactical sense to each shift. Compatible with SRAM 11-speed chains, it integrates 11-speed type sprocket spacing to guarantee precise and silent shifting.

Technical Highlights

• Two variants for all freehub bodies: The CS-PG-720-A2 model (EAN 710845919374) is supplied with a removable spacer that allows adaptation to both standard HG freehub bodies and new slim DH 7-speed freehub bodies. Simply remove the spacer to mount the cassette on a slim body.
• Lightweight and compact architecture: With only 7 sprockets, this cassette frees up valuable space around the spokes, improving rear wheel clearance and reducing interference risks.
• Integrated spoke guard: A specific protection prevents the derailleur from coming into contact with the spokes, securing your wheel during impacts and violent compressions on descents.
• Compatible with SRAM X01 DH and GX DH drivetrains: This cassette integrates perfectly with SRAM DH Type 3 X-HORIZON rear derailleurs and GX DH or X01 DH shifters, guaranteeing reliability and shifting precision under extreme stress.
• Pure gravity design: Fewer sprockets = less time wasted shifting up through gears, more reactivity and maximum efficiency on timed sections.

Available Variants

• Variant A1 (CS-PG-720-A1): For standard HG freehub body only, without spacer. Ideal for classic setups.
• Variant A2 (CS-PG-720-A2): EAN 710845919374, manufacturer reference 00.2418.155.000. Supplied with removable spacer for compatibility with standard HG and slim DH 7-speed bodies. Maximum versatility.

Installation and Compatibility

The PG-720 cassette mounts on a Shimano/SRAM HG splined freehub body. Installation is simple: use the supplied spacer for standard bodies, remove it for slim DH 7-speed bodies. It works with all SRAM 11-speed chains, guaranteeing uniform wear and clean shifting even after hours of intensive downhill. Locking is done with a standard lockring.

For Whom?

This cassette is intended for bike park riders, downhill racing pilots and all those who favor gravity: shuttle, pure DH, committed freeride. If you're looking for a reliable, lightweight, affordable cassette designed for long downhill sessions, the SRAM PG-720 DH is the obvious choice. It allows you to optimize your drivetrain while keeping budget for your lift passes.
