Sterling 9.4mm Fusion Ion R Climbing Dynamic Rope Review

The IonR is the largest diameter rope in the fusion range. Sertling’s core construction improves all the specs, but retains the handling characteristics that won the original such a loyal following. The most substantial rope of the Fusion series, it remains a lightweight, high-performance entrant. It’s unique design is manufactured by first twisting multiple colored fibers into a single sheath-strand and then braiding the sheath to create the speckled pattern. It’s diameter is a great size for intermediate climbers looking to match a lightweight rope with performance while knowing that the diameter isn’t TOO thin for a beginner belayer.
