Extruded from 6061-T6 aluminum with a lightweight design, these spacers allow precise handlebar height adjustment by stacking between the headset and stem or above the stem on the steerer tube. Each kit includes five spacers in different thicknesses for a total adjustment range of 1mm to 20mm.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e6061-T6 aluminum construction\u003c\/strong\u003e – Extruded and CNC-machined aluminum alloy provides strength while keeping weight minimal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMultiple thickness options\u003c\/strong\u003e – Kit includes 1mm, 3mm, 5mm, and 10mm spacers that can be combined for precise height adjustment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLightweight design\u003c\/strong\u003e – Weights range from 6.7g to 8.2g depending on spacer thickness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1-1\/8\" steerer tube compatibility\u003c\/strong\u003e – Standard size for modern BMX headsets and forks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e22.2mm handlebar compatibility\u003c\/strong\u003e – Spacer inner diameter also fits standard 22.2mm (7\/8\") handlebars for bar-mounted spacer applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 6061-T6 aluminum, extruded and CNC-machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSteerer tube size:\u003c\/strong\u003e 1-1\/8\" (standard BMX\/MTB threadless headset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpacer thicknesses included per kit:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eTwo (2) x 1mm spacers\u003c\/li\u003e\n\u003cli\u003eOne (1) x 3mm spacer\u003c\/li\u003e\n\u003cli\u003eOne (1) x 5mm spacer\u003c\/li\u003e\n\u003cli\u003eOne (1) x 10mm spacer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal adjustment range:\u003c\/strong\u003e 1mm to 20mm (when stacking multiple spacers)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 6.7g to 8.2g per kit (varies by spacer size)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold as:\u003c\/strong\u003e Pack of five spacers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCompatibility and Ideal Use Cases\u003c\/h2\u003e\n\u003cp\u003eThese spacers fit BMX bikes with threadless headsets and 1-1\/8\" steerer tubes—the standard for modern BMX forks. Not compatible with threaded headsets (older BMX bikes with quill stems) or 1\" steerer tubes. The spacers stack on the steerer tube between the headset top cap and stem, or above the stem to raise handlebar height. Verify your bike uses a threadless headset and 1-1\/8\" steerer tube before ordering.\u003c\/p\u003e\n\u003cp\u003eBest suited for riders who need to adjust handlebar height for fit, comfort, or riding style preferences. Stack spacers below the stem to raise the handlebars, or remove spacers to lower them (note: lowering requires cutting the steerer tube shorter or flipping spacers above the stem). The multiple spacer thicknesses allow precise height tuning—for example, use both 1mm spacers plus the 5mm spacer for a total of 7mm adjustment. Ideal for dialing in cockpit position during bike setup, accommodating rider growth, or adjusting bar height for different riding styles (higher bars for cruising and comfort, lower bars for racing or aggressive riding). \u003cstrong\u003eImportant: The steerer tube must extend through the stem with at least 3-5mm of tube protruding above the stem top for proper headset preload.\u003c\/strong\u003e If adding spacers causes insufficient steerer tube protrusion, you cannot safely add more height without a longer steerer tube. The 22.2mm inner diameter also allows these spacers to be used on handlebars for applications like raising brake lever or grip position, though this is less common.\u003c\/p\u003e \u003cdiv\u003e\u003cp.\u003e\u003ci\u003e\u003cu\u003e\u003cfont size=\"2\"\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/font\u003e\u003c\/u\u003e\u003c\/i\u003e\u003c\/p.\u003e\u003c\/div\u003e\u003cdiv style=\"\"\u003e\u003ci style=\"font-size: 0.875rem;\"\u003e\u003cu\u003e\u003cfont size=\"3\"\u003e\u003cb\u003e\u003cbr\u003e\u003c\/b\u003e\u003c\/font\u003e\u003c\/u\u003e\u003c\/i\u003e\u003c\/div\u003e\u003cdiv style=\"\"\u003e\u003ci style=\"font-size: 0.875rem;\"\u003e\u003cu\u003e\u003cfont size=\"3\"\u003e\u003cb\u003e**Due to unique nature of this item, ALL sales of this product are FINAL.
