Direct mount chainrings provide significant weight savings over a standard spider and chainring combination. They are crafted from CNC machined 7075 aluminum, and feature an anodized finish for exceptional durability. Ovality has been optimized for each chainring size, ranging from 10.2 - 14.4%, with timing of 110.5-116.3° after TDC (top dead center).

• Oval shape reduces stress on knees, helps to keep your legs fresh, and does not feel any different while riding
• The unique patent-pending narrow-wide tooth profile keeps the chain in place
• Teeth have been 3D-machined for ultimate mud shedding and quieter operation
• Provides excellent weight to strength ratio
