Special Carbon Extension for Adam This set includes two types of weight bolt bumpers (Aluminum 15g, Steel 36g) along with a dedicated hex key (8mm) for connecting. By removing the weight bolt currently attached to your Adam cue and replacing it with this product's bumper-equipped bolt, you can install the separately sold carbon extension.

The existing weight bolt uses a hex key (6mm) standard. If you do not have one, please purchase separately the "【Mail Available】 Maintenance Hex Key (6mm)".
