The SteelFiber i125 is generally preferred by players looking to maintain the overall club weight and effort it takes to swing their golf steel shafted irons but want to benefit from the stability of the SteelFiber and the vibration dampening characteristics of a graphite shaft. S Flex only available.

The i125 is available in both Taper tip and parallel tip configurations. All Taper tip models also incorporate a ‘Constant Weight’ feature. Therefore each shaft within the set (regardless of length) weigh the same.
