Ultra-light Frame Bungs

I designed these to keep frames fully sealed during bikepacking trips, without the need to install frame bolts in every unused mounting point (bottle cage, mudguard, rack mounts, etc.). They provide a simple way to waterproof exposed threads, while also cutting unnecessary weight. A set of 10 weighs just 1.2g, compared to roughly 50g for 10 standard 12mm bolts. They simply thread in by hand. Pack of 10. Trade quantities also available - contact us. Lightweight, practical, and purpose-built for clean, weather-resistant setups.
