Get that fashionable 40 or 42 tooth upper range, in a more economical form. The SunRace MX3 10-SPEED Cassette might be your answer. It works on most current 10 speed systems from Shimano and SRAM, by simply replacing the current 10 speed cassette with this larger one. It’s also a more cost effective way to go than the aftermarket expander rings, most of which can leave an uneven step in the cassette where another cog needs to be removed. This is a smooth and seamless block of cogs, designed for smooth and even gearing while giving the maximum range. The cassette works with most medium and long cage rear derailleurs, but may require a longer B screw. We’ve found that the 40 tooth works best with Shimano drivetrains and either the 40 or 42 is no problem with SRAM.
