absoluteBLACK oval rings are the only scientifically proven oval chainrings on the market. Oval chainrings don't produce more power, they increase your pedalling effectiveness. This means they reduce the component of your pedal pushing force, which doesn't contribute to moving your bike forward. The less force you waste the more energy you preserve, allowing you to push harder when it counts or simply reduce tiredness. 

This is the original one and only absoluteBLACK Premium Sram compatible Direct mount BOOST 1X Oval narrow wide chainring designed for GXP, DUB and Long BB30 spindle cranks. This chainring is dedicated for Boost bikes (3mm offset). It is 100-percent optimized for Eagle. This oval chainring with 3mm offset converts any Sram crank into Boost specific setup. Boost and non-Boost Sram cranks are identical. All the offset is achieved by the chainring itself.
