FAQs
Will this fit a 10-speed drivetrain?
No, this cassette is specifically engineered for 11-speed systems.
Do I need a special tool to install it?
Yes, you will need a standard HG cassette lockring tool and a chain whip.
Is this cassette compatible with electronic shifting?
The cassette is compatible with most 11-speed electronic road groupsets that support an 11-34T range.
What is the weight of the cassette?
The weight is approximately 278g to 291g depending on specific manufacturing tolerances.
Can I use this on a mountain bike?
This is designed for road/gravel spacing. While it may fit, mountain bike derailleurs often perform better with wide-range MTB-specific cassettes.
Troubleshooting
Difficulty shifting into the largest 34T cog
Adjust the B-tension screw on your rear derailleur to increase the gap between the upper pulley and the cassette.
Excessive noise while pedaling
Check that the cassette lockring is tightened correctly and ensure the chain is properly lubricated.
Cassette feels loose on the freehub body
Verify that all spacers are included and the lockring is fully torqued to 40Nm.
Pros and Cons
Pros
- Wide 11-34T gear range offers great versatility for mixed terrain
- Super Fluid Drive technology provides noticeably smooth shifting
- Lightweight design weighing under 300g
- Compatible with standard HG freehub systems
- Durable construction suitable for daily city or gravel use
Cons
- Requires a medium or long cage rear derailleur for the 34T cog

- Silver finish requires regular cleaning to maintain aesthetic appeal
Setup, Compatibility & Care
Installation
- Ensure your freehub body is clean and free of debris.
- Slide the cassette onto the HG splines, aligning the wide spline with the corresponding groove.
- Install the lockring and tighten to the manufacturer-specified torque (typically 40Nm).
- Check your B-tension screw on the rear derailleur to ensure the pulley wheel clears the 34T cog.
Compatibility
This cassette is strictly for 11-speed Shimano/SRAM HG compatible systems. It is not compatible with XD or Microspline driver bodies. Always verify that your rear derailleur has the capacity to wrap the chain for an 11-34T range.
Maintenance
Clean the cassette using a degreaser and a stiff brush every 200-500 kilometers, depending on riding conditions. Applying a high-quality chain lubricant will help maintain the performance of the shifting ramps.
