Product Information
Full details
The SunRace MX3 10-Speed Cassette is an ideal upgrade for mountain bikers utilizing a 1x10 drivetrain who require an expansive gear range without the complexity or cost of aftermarket expander sprockets. By offering a wide 11-46T range in a single unit, it provides excellent climbing capabilities and smooth gear transitions; however, users must ensure their existing rear derailleur has the necessary cage length and capacity to accommodate the 46T cog.

FAQs
Will this fit on a standard Shimano HG freehub?
Yes, this cassette is designed to fit on standard 8, 9, and 10-speed Shimano-compatible mountain bike freehub bodies.
Do I need a new chain for this cassette?
When upgrading to a larger cassette, you generally need a longer chain. It is recommended to size your chain using the 'big-to-big' method plus two links.
Can I use this with an 11-speed derailleur?
No, you must use a 10-speed shifter and a 10-speed derailleur to maintain proper pull ratios and indexing.
What is the weight of the cassette?
The MX3 11-46T is designed to be lightweight, typically weighing around 465 grams depending on the production batch.
Is the largest sprocket replaceable?
The sprockets are generally riveted to the spider carriers, so individual sprocket replacement is not standard; the unit is replaced as a whole.
Is the alloy lockring included?
Yes, the package includes the matching alloy lockring required for installation.
Troubleshooting
Derailleur hitting the largest cog
Adjust the B-tension screw on your rear derailleur to increase the clearance between the upper pulley wheel and the 46T sprocket.
Hesitant shifting between gears
Check your derailleur hanger alignment and ensure your shift cable tension is properly indexed.
Cassette feels loose on freehub
Verify that all provided spacers are installed correctly and that the alloy lockring is tightened to the recommended torque specification.
Pros and Cons
Pros
- Eliminates the need for external expander cogs
- Lightweight construction via alloy spiders
- Excellent value for 1x10 drivetrain conversions
- Durable A7075 aluminum largest sprocket
- Smooth shifting performance with Fluid Drive technology
Cons
- Requires derailleur with sufficient capacity
- May require a derailleur hanger extension on some frames
- Heavier than high-end 11 or 12-speed systems
- Requires 10-speed specific shifters and derailleurs
Setup, Compatibility & Care
Installation follows standard cassette removal and installation procedures using a Shimano-style lockring tool. Ensure your freehub body is clean and lightly greased before sliding the cassette into place. Because of the large 46T cog, you must verify that your rear derailleur can handle the maximum sprocket size; if it cannot, a 'RoadLink' or similar derailleur hanger extender may be required.
Chain length will likely need to be increased compared to your previous smaller cassette to prevent damage in the largest gear. Regularly clean the cassette with a degreaser and a stiff brush to maintain the integrity of the Fluid Drive teeth and prevent premature wear from grit accumulation.
