What Our Gearhead(R) Experts Are Saying:"I needed to dial in the stack height on my ENVE IN-Route cockpit, and this spacer kit made the whole process seamless. The fit is super clean-no weird gaps or mismatches-and it keeps everything looking as sleek as it rides. I always keep a couple sizes on hand when I'm building or adjusting integrated bikes."Clean cockpit integration demands precise fitment, and the ENVE HW Headset IN-Route Spacer Kit gives us just that. Designed to work seamlessly with ENVE's IN-Route System, these front and rear spacers help us adjust stack height without compromising the bike's aerodynamic profile or cable routing. Available in 5mm and 10mm kits-plus a Bypass version for alternate routing setups-the spacers maintain a tight interface with IN-Route stems and headsets, delivering a flush, pro-level aesthetic. Whether we're making micro-fit adjustments or doing a full build from scratch, these components make sure everything stacks up perfectly.
