Absolute Black Oval MTB Chainring 1x SRAM DM BOOST148 (3mm Offset)

The Original one and only absoluteBLACK Premium Sram compatible Direct mount BOOST 1X Oval narrow-wide chainrings are designed for GXP, DUB, and Long BB30 spindle cranks. This chainring is dedicated to Boost bikes (3mm offset). They are 100-percent optimized for Eagle. It is the most Premium oval chainring on the market with scientifically proven performance gains.

This oval chainring with a 3mm offset converts any Sram crank into a Boost-specific setup. Boost and non-Boost Sram cranks are identical. All the offset is achieved by the chainring itself. Our regular OVAL chainrings for Sram cranks have a 6mm offset while this one has 3mm.

Advantages of Our Special Direct Mount Narrow-Wide Chainrings:

• Finest design to provide an excellent weight-to-strength ratio
• One-of-a-kind special oval shape (Patent Pending)
• Greatly improves traction and climbing abilities
• Unique Patent Pending alternate wide and narrow teeth profiles to keep your chain in place for a minimum of 12 months!
• Special 3D teeth machining for ultimate mud relief decreases wear and noise dramatically
• They save weight because they don't need the spider and chainring bolts.
• The ability to install smaller ring sizes that can't be mounted on the regular spider.
• Superb quality and great look.
• You will ride faster using ovals. If you keep using a round ring then others will get quicker.
• You will not "feel" the oval shape at all
• Reduces stress on knees
• We mastered our oval chainrings to perfection, so you can get the best possible advantage from the oval/elliptical shape.

How to Mount Our Oval Chainring to Sram GXP and BB30 Crank:
You need to unscrew these 3 Torx t-25 bolts from the crank. Then remove the spider+chainring combo you currently have there. Clean the splines and put some grease on them. Position the chainring in place (note there is only one way to fit this chainring to the Sram crank, so you don't have to worry about how to do it). Close all 3 bolts to about 5-7Nm.
