Full Speed Ahead Mallet Headset

The Mallet is an EC34 external cup headset designed for frames with a 34mm head tube inner diameter. It is compatible with standard 1.125-inch straight steerer tubes, so be sure to check your frame's head tube standard before purchasing.

This headset is engineered for aggressive riding styles, including trail and street use. Its heavy-duty construction and oversized chromoly bearings are specifically designed to handle the high-impact abuse that standard headsets might struggle with.

Because it uses a traditional external cup design, installation is straightforward for anyone with basic bike mechanic skills. You will need a standard headset press tool to seat the cups into the frame properly.

The caged ball bearing system used here is a classic, proven design that is easy to service and maintain. While it requires a bit more attention than a sealed cartridge system, it offers excellent durability and impact resistance for rough riding conditions.

The stack height is 15.4 mm. This measurement is important because it dictates how much space the headset takes up on your steerer tube; you need to ensure you have enough steerer tube length remaining to accommodate this height along with your stem and spacers.
