If you want to increase your effective fork length on your frame then Wolf Tooth have you covered with these sweet Lower Headest Cup Extenders. They give you the ability to use a rigid fork on a suspension corrected frame or use a fork with a shorter axle-to-crown height rather than what the frame was designed to use.

You can also use them to increase the bottom bracket height and lower the head tube angle.

Who's this item for: Anyone with a compatible frame looking to adjust the geometry of their frame by increasing the effective fork length by 10mm

Compatibility:

EC49: Any frame that uses an external cup headset with a 49mm lower head tube inner diameter.

ZS56: Any frame that uses a zero stack headset with a 56mm lower head tube inner diameter. These ZS headsets are for frames with internal bearing cups that are pressed into the frame.

What's in the box:

• Headset Cup Extender
• Enduro stainless steel sealed bearings included

Note: Upper and lower headsets are sold separately. This is just the extender.
