What Our Gearhead(R) Experts Are Saying: "I always keep a set of these in my toolbox. They're clutch for dialing in bar height after swapping stems or forks. The weight's negligible, and I like that I can fine-tune the stack height with 1. 5mm and 2. 5mm options, not just the standard big spacers."Cockpit setup isn't one-size-fits-all. The Leatt Spacer Kit Headset lets us fine-tune our ride feel with a lightweight, precision-cut set of spacers designed for 1 1/8-inch steerer tubes. Whether we're adjusting bar height for more control on descents or finding that perfect XC climbing position, these spacers give us the options we need without adding unnecessary grams. This four-piece kit includes 1. 5mm, 2. 5mm, 5mm, and 10mm spacers-each machined for a clean fit and minimal weight. The total set weighs just 16 grams, making it a must-have for builders, tuners, and perfectionists.
