NanoSpeed Iron, 7-iron. Flex: R-1 These irons are easy to hit and fly far. Purchased from a used golf shop. Regarding the shaft, I do not know if there have been any modifications (re-shafting, shaft cutting, extensions, etc.). I can only judge based on the appearance. As these are used clubs, there are signs of use (ball marks, scratches, dirt, rust). The listed specifications are based on the data from the shop at the time of purchase. We do not accept claims or cancellations after a successful bid. Please ask any questions you may have before bidding. I will answer to the best of my ability.
