Special sleeve shaft

The strongest playing style has evolved even further
|
This is the world's first application of ultra-high modulus 90t carbon to the entire length of a golf shaft.
By suppressing shaking during the swing, it becomes much easier to swing, and by reducing impact loss, it gives you an unprecedented feeling of release.
Ultra-high elastic carbon fiber "90t carbon" By layering the world's hardest material, 90t carbon, we have achieved maximum acceleration and impact strength.
By suppressing shaking during the swing, it becomes much easier to swing, and by reducing impact loss, it gives you an unprecedented feeling of release.
Toray's cutting-edge carbon fiber "TORAYCA M40X" exceeds T1100G
Full-length laminate, just like the DAYTONA SPEEDER.
By pursuing both fiber strength and elastic modulus, which are in a trade-off relationship, to the limit, we have achieved an approximately 30% increase in strength while maintaining the same elastic modulus as conventional carbon fibers.
It produces a superior playing feel and feeling.
Ultra-low resin carbon sheet "RC15% prepreg" 40g/50g/60g
A carbon sheet with an ultra-low resin content of "RC15%", which has been further reduced to the bare minimum from RC20%, is laminated.
By reducing the amount of resin, the ratio of carbon fiber is increased, resulting in a dense shaft.
Wasted movement is eliminated, resulting in stronger spring back.
