BLB Headset Spacer 1 inch - Silver

If you have a threadless 1-inch fork and need to adjust the height of the stem, the BLB Headset Spacer is a simple little part that does exactly what it should. It fits, among others, older track and road bikes with 1" Ahead systems, such as the Bianchi Pista, and forks from brands like Wound Up.

The spacer rings are available in 2, 5, and 10 mm and can be combined to position the stem and top cap at the correct height. This is especially useful on 1-inch builds, where the range of spacers is considerably smaller than for today’s more common 1 1/8" standard.

They are made of aluminum with a silver finish and can also be used on certain threaded 1-inch forks when you need to add height to the headset. In that case, of course, you need to check that the steerer tube’s threaded length and the headset assembly allow it.

A small component, but useful to have when a few millimeters are all that is missing to make an older 1-inch build fit just right.
