Although it seems a tad heavier than the big brands, this cassette has everything I’m looking for. Since I don’t own any 11-36 10 speed cassettes from other brands, I can’t confirm SunRace is actually heavier! I purchased this cassette due to its competitive price, for quality of build. Like Shimano and Sram, largest cogs are all on a carrier, making the weight and strength seem right on par. Metal finish appears as a durable bright silver, so it should last a good long time. Teeth have a similar angles to that of my 11-34 XT cassette. Uphill shifting, under a load, proves the design works. Easier on the wallet is the best part, so I plan to outfit my other rough and tumble bikes with SunRace.
