These rings will allow you to convert your 120 BCD crankset, like the SRAM XX and others, to a 1x drivetrain.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits 120 BCD cranksets or 4-bolt spiders\u003c\/li\u003e\n\u003cli\u003eDrop-Stop technology. On Wolf Tooth’s patented wide\/narrow chainring, the wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life.
