Cyclists and bike mechanics, this Wheels Manufacturing headset spacer kit is some seriously smart engineering! The StackRight technology is genius - it locks the spacers together with an interlocking channel so they always stay perfectly aligned, giving your bike a clean, professional look instead of that messy stacked spacer appearance. The kit fits standard 1-1/8 inch threadless fork steerers with an inner diameter of 28.9mm and outer diameter of 34.4mm. The precision-machined 6061 aluminum is lightweight yet durable, and the black finish looks sleek on any bike. You get a complete set of spacers in multiple thicknesses: 1.5mm (2 pieces), 2.5mm (2 pieces), 5mm (1 piece), and 10mm (2 pieces) - that's plenty of combinations to get your handlebar height dialed in perfectly. The kit also includes a standard headset cap and M6 x 35mm stainless steel bolt for complete installation. The quality is immediately noticeable - clean machining, perfect finishes, and the interlocking system works smoothly. Whether you're building up a new bike, adjusting your fit, or doing maintenance, having a quality spacer kit like this makes the job so much easier and gives you professional results. The StackRight system really does eliminate that annoying spacer shift that can happen with regular spacers, especially on rough roads or trails. If you're tired of your headset spacers looking messy or shifting out of alignment, this kit will give your bike that clean, pro-built appearance while making future adjustments much simpler. Definitely worth the upgrade from basic spacers!
