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).
Installing the CSMX3 cassette was easy thanks to SunRace’s use of alloy spiders for the six largest cogs. In addition to saving some weight over separate steel cogs, the machined spiders are less likely to damage the splines on lightweight aluminum free hub bodies. Other niceties include alloy cog spacers (as opposed to plastic), and an alloy lock ring anodized to match the spiders’ red color.
Having used Shimano and SRAM cassettes exclusively for as long as I can remember, I was initially concerned that the SunRace unit wouldn’t offer the same level of performance. The bottom line is that I was dead wrong–the SunRace cassette sacrifices nothing when it comes to shifting performance. And despite being removed and reinstalled multiple times (on different bikes and wheels), I never encountered any creaking or popping when pedaling (and shifting) under load.
Much of my testing took place in between heavy snow storms, which meant wet and gritty conditions. It’s too soon to comment on the CSMX3’s long-term durability, but I haven’t noticed any premature wear on either of the sample cassettes. Look for a future update to see how the SunRace unit holds up to typical Colorado winter riding.
