The philosophy of RCore grip design is to provide a product without any manufacturing restrictions.
This means we start with the design and work around any material constraints.
As a result, the tolerances of the RCore grips are tighter than your usual OEM grip, which is why we may ask for additional measurements. This is especially true for W&W risers, whose width can vary even within the same model, depending on the riser size, date of manufacture, and paint/anodizing style.
Moreover, some designs call for delicate dimensions and thicknesses on the grip. It is not unusual to have a grip with one millimeter of material at the throat to accommodate the original design specifications.
Of course, the design could be adjusted to add bulk but this would defeat its purpose. For this reason, the grips should be treated as any other delicate part of your bow.
You should protect them from the elements (extended direct sunlight, excessive forces irrelevant to shooting) and take care of the stand you are using. Don’t drop it on the stand and ensure the hook is smooth to prevent scratches on the surface of the grip. All grips have a 30-day warranty for defective materials or manufacturing. If something is wrong, it will present itself when you put the grip on.
Here’s what you need to know about the recent changes:
While new import tariffs have been introduced, they only apply to orders shipped to the USA if the total value exceeds $800 (including postage).
This means all orders under $800 will continue to pass through customs without any additional fees or charges.
Our workshop is based in Greece, so shipments within the EU are not affected. For all non-EU countries, import conditions remain the same as before.
