• Evolve outer and middle chainrings are built from 7075-T6 aluminum for increased wear resistance & impact strength.
• Evolve 22T granny ring is made from high strength, heat-treated CrMo steel with a satin chrome plated finish for maximum durability.
• Engineered with a focus on optimizing the chain to ring interface, Evolve rings shift flawlessly, even under load.
• Sweet rings for a reasonable price.

Great looking CNC rings with a black anodized finish and CNC chamfered edges to the cut outs. Riveted shifting plates and plenty of complicated ramps produce great up shifting. The granny ring is steel, which makes perfect sense to us. The anodizing seems to withstand scrapes and stupidly muddy rides very well. Available in four bolt 104/64 pattern. Verdict: Good shifting, good looks ."
