Frequently asked questions
Is this a complete club or a component?
This listing will have a stock shaft and grip as stated above unless you choose to customize your club or set. The price and selected options without customization will include STOCK shafts, grips, ferrules, adapters and assembly unless the Shopify selection explicitly says they are included.
Can Grater Golf help with a custom build?
Yes. Contact us with the exact head, shaft, flex, grip, playing length, loft/lie preferences and any swingweight goal. We can confirm compatibility and available services before purchase.
Should I choose taper-tip or parallel-tip?
Match the shaft tip to the hosel specification shown in this listing. A .355 taper shaft and .370 parallel shaft are not interchangeable without appropriate professional modification, which is not recommended unless the builder has verified the process.
Build with confidence
Ask Grater Golf about your Sub 70 setup.
We’ll help confirm the model, handedness, loft, shaft compatibility and assembly plan.
