Sunrace ms3 10 speed shimano and sram cassettebringing wide range gearing to riders with 10 speed mountain bike mtb drivetrains, the ms3 shimano and sram compatible cassette enables you the ability to remove your front gears in favour of a simpler 1x system. This shaves weight from your ride yet still gives you the gears you need for quick acceleration and easy climbing ability. To ensure excellent rigidity and durability with this mtb cassette, sunrace has constructed its first six sprockets onto two alloy spider carriers. The added benefit of this is improved power transfer, as unwanted flexing is prevented as youre powering over rough sections and attacking steep hills.
