LIN-Q M40X TSPX Blue is designed for the golfer seeking a mid-launch and low spin

LIN-Q M40X features our exclusive Q-fiber combined with the revolutionary M40X fiber.  UST Mamiya engineers have created 3 new, higher-performance LIN-Q shafts with increased strength and phenomenal feel. Incorporating M40X into the new shaft designs provides significantly improved lateral stability to the shafts during the golf swing, thereby delivering increased energy to the golf ball at impact. 

M40X HIGH TENSILE MODULUS  Revolutionary Material |  Innovative Design

M40X represents a major advance in carbon fiber technology. TORAY Industries pushed both fiber strength and tensile modulus to the extreme and applied technology to improve fiber orientation by closely controlling the graphite crystal structure in a nano order. The result is a revolutionary material that offers a 30% improvement in tensile strength over conventional carbon fiber.

M40X eliminates the “boardy” feel through the use of proprietary nano technology and nanoalloy used in the prepreg matrix resin. This novel combination significantly improves shaft feel and performance.

The absolute best place to order club making parts, especially adapters. The crew at Billy Bob's is extremely knowledgeable, and stand behind all of their products. I will never use eBay, Amazon, or GolfWorks for ordering specialty parts for clubmaking again. The customer service at Billy Bob's and the quality of the product is above all others for aftermarket building materials and they will treat you like family if you ever have any questions or concerns. On multiple occasions I have had a problem or question and they always pick up the phone with helpful answers and even have offered full replacements of their product when I lost a part. The best ever at what they do and I will never go anywhere else for my clubmaking materials.

Justin from Billy Bob's helped me getting my clubs re-shafted. He was very considerate about getting swing weights to be the same throughout my iron set. I needed to change lie angles for the irons as well as my grips. Phenomenal job on the whole set and I respect his craftsmanship on the work he has done for my irons. I am glad I was able to visit this store and got this job done here.
