Sunrace Sturmey-Archer is a manufacturer of traditional dérailleur drivetrain systems as well as internally geared drive-train transmissions. Sunrace was founded in 1972 and Sturmey-Archer was founded in 1902.
They are producing rear 10 and 11 speeds MTB wide cassettes. Those cassettes are a good and affordable solution usually better that mounting an extra super large ring kit on your cassette. It has a more progressive overpass and a better compatibly : SRAM dérailleurs are generally compatible, Shimano dérailleurs require a longer B-tension screw.
Let s take a look at those 10 speeds models.

10 SPEEDS WIDE CASSETTES – SUNRACE CSMS3 & CSMX3

The two Sunrace 10 speed wide cassettes come directly in front of the HOPE 10S wide Cassette and mainly the PRAXIS 10s wide Cassette.  While the HOPE start with a small 10T sprockets (10/42), the 2 Sunrace models CSMS3 and CSMX3 starts, like the PRAXIS, with an 11t sprocket. It fits perfectly on a traditional Sram or Shimano freehub.
Both models are available in 2 wide range : [AX] 11-40 (11-13-15-18-21-24-28-32-36-40) or [AX] 11-42 (11-13-15-18-21-24-28-32-36-42). The 6 first are independents (11-13-15-18-21-24),  next (28-32) are on one single alloy sprocket, same for 2 last one (36-42 or 36-40).

The main difference is that the CSMX3 (387g(AY) / 378g(AX)) is designed with largest sprockets (40 & 42) made of Aluminium 7075 while the CSMS3 (448g(AY) / 414g(AX)) is 100% made of  steel, that globally explain the weight difference.

They are generally compared to 10speed Shimano XT cassette, the shifting is working well but you ll need to put a special attention to the adjustment for the largest sprocket. SRAM dérailleurs are generally compatible, Shimano dérailleurs require a longer B-tension screw. It is definitely the best alternative to expander cog kit like One Up, zero risk to twist the sprocket by lack of rigidity.
