Absolute Black



The Original, the one and only absoluteBLACK premium Sram compatible Direct Mount BOOST148 1X Oval Narrow-Wide Chainrings are designed for GXP, DUB, and Long BB30 Spindle Cranks. Chainring is dedicated for Boost148 bikes ONLY. Converts a regular Sram Crank into a Boost specific setup. (3mm offset). They are also 100-percent optimized for Eagle.

This Cinch DM Oval Boost Chainring with special 3mm offset converts any Sram Crank into a Boost148 specific setup needed in Boost equipped bikes. Boost and non-Boost Sram Cranks are identical. All the offset is achieved by the chainring itself, so you can use any Sram Crank for this conversion.
