SRAM presents new direct mount chainrings

The US component giant SRAM is launching an update for its popular single cranks. The chainring and spider arm are now one piece, which has a positive effect in terms of weight and simplicity. SRAM is also focusing on a wider range of 26 to 40 teeth.

The cranks of SRAM's XX1, XO1 and X1 single-speed drivetrains are known for their spider arm and replaceable chainring. SRAM is now dispensing with a single spider arm and producing it in one piece together with the chainring. This reduces the weight by 25 to 50 grams depending on the chainring size. This also makes it easier to change them, as the whole thing is only fixed to the back of the crank with three bolts.

SRAM is also going one step further with the gradation. A 26 mm and a 40 mm chainring have been added. In between, these each increase by two teeth. These aluminum chainrings were developed in Germany and continue to be based on X-Sync tooth technology.
