Product Review by Gravelbike
Local supplier Two Wheels TradingUntil recently, riders seeking cassettes larger than 36 teeth had two options: aftermarket extender cogs or SRAM’s XD-based free hub/cassette system. Now, there’s a third option with SunRace‘s line of wide-range cassettes. The company’s cassettes fit standard Hyperglide-compatible free hubs, and are available in 10- and 11-speed versions.
SunRace offers their wide-range 10- and 11-speed cassettes in two versions: the all-steel CSMS3, and the CSMX3 which features an alloy 40t or 42t cog. The aluminum large cog saves approximately 60 grams, with my sample 11-42t MX3 cassette weighing 389 grams (two grams over the claimed 387-gram weight).
