SRAM narrow/wide chainring for 1 chainring and cassettes with 10 or 11 gears (speed).

The narrow/wide blades are made so that every other tooth is wide and every other is narrow, in this way the blade grips the chain so that the chain does not fall off. This type of chainring is used on singlering setups where there is no front derailleur or chain guide.

Fits both GXP and BB30 cranksets with 110mm fixed dimensions.

Material: aluminium.

Colour: Argon grey.

42 teeth.
