The Premium absoluteBLACK Sram compatible Direct mount BOOST 1X Oval narrow wide chainrings in PVD Rainbow (oil slick) coating. Designed for GXP, DUB and Long BB30 cranks. This special PVD Rainbow Titanium coating process makes the chainrings very durable and incredibly beautiful.
NOTE: Due to the nature of PVD process, every chainring is unique and color may vary. Not a single chainring is the same which makes your new ring completely individual. You can indicate to us, in comments section during the checkout, if you prefer more gold-purple or more blue/green-purple, but we can not guarantee to meet your request.
