Enduro fans and weight fetishists take note: In December, Sram is launching a new chainring for its single-speed drivetrains. The new chainring was developed in Schweinfurt and can be combined with the XX1, X01 and X1. The highlight: The new chainring is mounted directly on the crank ("Direct Mount"). This eliminates the spider, which simplifies assembly and also saves weight. Between 25 and 50 grams depending on the size of the chainring.
Better self-cleaning with sludge
The profile of the new X-Sync chainrings has also been revised compared to its predecessors. Higher teeth should ensure that the chain contacts the chainring earlier, which increases the efficiency of the drivetrain. The chainring has also been optimised for better self-cleaning in muddy conditions. It almost goes without saying that thin and thick teeth alternate to keep the chain in place at all times and make a chain guide superfluous.
X-Sync: From 26 to 40 teeth
The chainring will be available in Germany with 30, 32 and 34 teeth from December 2014, while those who prefer 26, 28, 36, 38 or 40 teeth will have to wait until April 2015. The chainring is compatible with XX1, XO1 and X1 cranks where the spider can be unscrewed and costs 88 euros.
