The ChainFlow 3D technology found on their chainrings utilizes a T-shaped tooth profile which hugs the chain tight. The chain stays glued to the ring even while shifting in the most extreme trail conditions. Strengths - Modular design where the crank arms, spindles, and spider/chainring are completely interchangeable - Very lightweight - Titanium spindle for size and weight - Spectacular chain retention - Great looking gloss finish - Quick chainring/spider changes
