Because of its strength/weight ratio, this is the go-to chain for riders across a multitude of racing disciplines, especially among the 250 class.
The new 520ERT3 has been upgraded with improved plate material. As a result, 50ERT3 has 25% greater "Anti-shock performance" and 3% higher Tensile Strength without changing the weight.
What is "Anti-shock Performance"?
