Front Boost Adaptor - Chris King ISO

Machined in Whistler, Canada from stainless steel.

Converts your 100mm front hub to Boost spacing, using an extended drive side end cap. You will also need to dish your wheel by 5mm to the drive side, to center your rim.

Choose the 18mm option if your hub has the removable split-type end cap on the drive side. This measurement refers to the diameter of the end of the hub axle without the end cap installed.

Choose the 21mm option if your hub does not have a removable end cap. This measurement refers to the diameter of the end of the hub axle.

See pictures for clarity.
