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

The CS-MX3 is the perfect upgrade for riders who want to reap the benefits of wide-range cassettes without upgrading to a completely new drivetrain. The CS-MX3 offers a wider range than any stock SRAM or Shimano 10-speed cassette. The CS-MX3 is available in two different ranges: 11-42T and 11-40T.

The largest cog is 7075 Aluminium to keep weight down while the remaining cogs are constructed from durable steel. The largest 6 cogs are also split onto two aluminium spiders for further weight savings and to help prevent freehub wear. This cassette will 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, due to the increase in range, a longer chain is likely required.

Features:

• Compatible with all splined freehub bodies. Will not work with SRAM XD drivers.
• Largest cog is 7075 aluminium and the remaining cogs are steel.
