Garbaruk 12 speed GEN2.0 cassette Shimano Microspline

Lightweight, Smooth and Trail-Ready

The Garbaruk 12-speed GEN2.0 cassette is the latest evolution of their Micro Spline MTB cassettes. It blends cutting-edge CNC machining, ultra-lightweight materials and a wide gear range to tackle climbing, sprinting and technical descents with ease.

Unlike mass-produced cassettes, Garbaruk machines the GEN2.0 with tight tolerances and precision-made tooth profiling to improve chain engagement, reduce drivetrain drag, and deliver crisp, predictable shifting under load. This cassette doesn’t just save weight: it improves how your whole drivetrain feels when you're out on the trail.

🚴 Why Upgrade to the GEN2.0?

If you loved the original 12-speed Micro Spline cassette, the GEN2.0 takes what you love and refines it even further:

• Optimised Gear Steps: Revised spacing provides smoother cadence transitions and more efficient power transfer on steep or rolling terrain
• Reduced Rotational Weight: CNC-machined chromoly steel paired with 7075-T6 aluminium for the largest cog keeps weight low
• Enhanced Durability: Nickel-plated steel improves corrosion resistance, and the monoblock design ensures reliability under high torque
• Improved Shift Feel: Refined tooth shaping and chamfering promote faster chain pickup and more controlled shifting under power
• Broader Use Case: Strong enough for aggressive trail riding and suitable for e-MTB torque loads while remaining one of the lightest options in its class

🧠 Why Riders Choose Garbaruk Over Other Brands

Garbaruk cassettes are built for riders who value performance, not just numbers on a scale.

The monoblock steel construction (11 cogs from a single block) increases stiffness and alignment accuracy compared to pinned or riveted stacks. That means less flex under load, more precise indexing, and longer-lasting performance. 

In real riding terms, that means smoother shifting on steep climbs, better transitions under pressure, and a bike that responds instantly when you put power down.

👤 Who This Cassette Is For

• Riders upgrading from heavy OEM Shimano cassettes
• Performance-focused trail and marathon MTB riders
• Weight-conscious builds where rotating mass matters
• Riders wanting smoother shift transitions across a wide range
• e-MTB riders needing strength without huge weight penalties

If you're happy with a performance that's perfectly adequate, a stock cassette is fine. If you want your drivetrain to feel sharper, faster and more precise, however... well, you want Garbaruk.
