The MicroShift Advent CS-H093 9-speed 11-42T cassette embodies the philosophy of accessible and high-performance cycling: an economical single-chainring drivetrain offering a gear range wide enough to tackle all types of terrain, from pavement to technical singletrack. Designed for mountain bikers, bikepackers and gravel cyclists seeking durability, simplicity and unbeatable value, this cassette combines optimized gearing (11-42T) with continuously forged chromoly steel construction, guaranteeing shifting precision and longevity even under the extreme demands of eBikes.

Technical highlights of the Advent 9-speed cassette

• Perfectly calibrated "Wide Enough" gearing: The 11-42T range offers an ideal balance between small gears for steep climbs and large gears for powering down descents. The 9 cogs (11-13-15-18-21-24-28-34-42T) are progressively spaced to minimize double-shifting and immediately find the right gear.
• Continuously forged chromoly steel construction: Unlike stamped or assembled cogs, each sprocket is forged as a single piece, guaranteeing increased flatness and strength. Ramps and chamfers are precision-machined for fast and smooth gear changes.
• Enhanced heat treatment and ED Black finish: The improved heat treatment process gives the cassette exceptional hardness, making it compatible with eBikes and high-load drivetrains. The black electrodeposition finish protects against corrosion and wear.
• Shimano HG standard compatibility: Instant mounting on any Shimano/SRAM 8/9/10-speed freehub body without need for a specific hub. Uses a standard 9-speed chain (no expensive exotic chain).

Available variants

• 11-42T (EAN 4710495438320 / Ref. CS-H093 11-42): Balanced 450 g version, fully hardened chromoly steel cogs. Ideal for trail MTB, gravel and bikepacking.
• 11-46T (EAN 4710495438436 / Ref. CS-H093 11-46): "Super range" 595 g all-steel version, offering a 46T for the steepest climbs. Gearing: 11-13-15-18-21-24-30-37-46T.
• 11-38T (Ref. CS-H093 11-38): "Super Short" version designed for small-wheeled bikes or short cage installation. Gearing: 11-13-15-18-21-24-28-32-38T.

These three variants share the same philosophy of compatibility, durability and accessibility, while adapting to varied configurations and needs (wheel size, terrain difficulty level, target weight).

Compatibility and Advent system integration

The CS-H093 cassette is an integral part of the MicroShift Advent H-Series group, a 1×9-speed single-chainring system. It absolutely requires a MicroShift Advent derailleur (long cage or super short cage depending on variant) and an Advent shifter (Trail Trigger Pro, twist shifters, bar-end or integrated road levers). Warning: incompatible with Shimano and SRAM derailleurs due to a specific MicroShift cable pull ratio.

Durability, maintenance and eBike use

Thanks to enhanced heat treatment and forged one-piece construction, this cassette withstands the high torque of electric motors and the intense mechanical stress of aggressive MTB riding. The 450 g weight (11-42T version) makes it a competitive option compared to more expensive 10 or 11-speed cassettes. Maintenance is limited to regular cleaning and replacement of the standard 9-speed chain (economical and easy to find).

Origin and manufacturing quality

MicroShift, a Taiwanese brand founded in 1999, benefits from decades of expertise in bicycle drivetrain manufacturing. With facilities in Taiwan and China, the brand focuses on accessible innovation, rigorous quality control and cross-system compatibility. The Advent range, launched in 2019, quickly won over fans of simple, reliable and affordable drivetrains.
