Speed Plug Spire Aerodynamic Bar End Plugs For Track Bikes & Time Trials - Ceramic Coated 3D Printed

Serious cyclists listen up! These Speed Plug Spire bar end plugs aren't your average bike accessories - they're engineered for maximum aerodynamics and performance. The unique conical shape is specifically designed to create smoother wind flow over and under your track bars or bar extensions, reducing drag when every second counts. Perfect for track racers, triathletes, and time trialists who need that competitive edge. Made with toughened 3D print material using SLA technology, these plugs are surprisingly strong yet maintain that smooth, aerodynamic profile. The ceramic coating finish not only looks pro but adds durability too. Each pair weighs just 16 grams - seriously lightweight! They're sized to fit bars with 19mm to 21mm internal diameters, and they come with four O-ring locks (removable) that keep them securely in place no matter how intense your ride gets. The best part? These are made right here in the USA at our Tennessee facility, so you know you're getting quality craftsmanship. If you're tired of flat bar plugs that create turbulent air flow and want to upgrade to something that actually improves your aerodynamics, these Spire plugs are your answer. They're that perfect small upgrade that can make a real difference in your performance, especially when you're pushing for personal bests or competing against the clock.
