SunRace 10-speed cassettes are a great option for riders who want to get the most out of their 10-speed drivetrains. 

The CS-MS2 is the perfect upgrade for riders who want an affordable cassette without upgrading to an entirely new drivetrain.  The CS-MS2 offers a wider range than any stock SRAM or Shimano 10-speed cassette. The CS-MS2 is available in two different ranges: 11-42T and 11-40T.  

This cassette uses durable steel cogs which helps keep the cost low. The cassette will also fit on any splined freehub body and a few simple derailleur adjustments will have you enjoying the benefits of a wide range cassette. 

Please note: If you are going up in range with your cassette you will need a longer chain. 

Features:

• Compatible with all splined freehub bodies.  Will not work with SRAM XD drivers.
• Hi-Tensile steel cogs for the best durability. 
• 11-42 (494g), 11-40 (458g).
• 11-42t: 11-13-15-18-21-24-28-32-36-42. 
• 11-40t: 11-13-15-18-21-24-28-32-36-40

Please note: SRAM derailleurs should work without any issues. Shimano derailleurs may require a longer B-Tension bolt. If you are currently running the same cassette range now you shouldn't require a longer B-Tension bolt. 

A longer chain will also be needed!
