The NAC Enduro Fly puts your spare tube, tyre levers, CO₂, and multi-tool directly on your frame — no saddle bag, no backpack. Installed correctly it sits silent and secure on the roughest terrain. Loaded wrong, tools can rub your paint. Here's the right way, in two steps.
Step 1 — Load the strap
- Slot your multi-tool, tyre levers, CO₂ inflator and cartridges into the two elastic loops so each item is gripped firmly.
- Fold your spare tube flat and place it over the tools.
- Fasten the smaller Velcro strap around the tube and tools to make one tight bundle.
Step 2 — Mount it on the frame
- Place the bundle tube-side against the frame — the tube cushions the frame and gives the strap grip.
- Wrap the main strap around the frame tube and cinch it down firmly.
Three rules that matter
- Never run the Enduro Fly without a tube — the tube is what grips the frame and shields the paint from the tools.
- Check that no tools touch the frame directly after mounting.
- Keep brake and shift cables clear of the strap's path before tightening.
Give the bundle a firm tug before riding — there should be zero rotation or slide. Not sure what to load? Our checklist of what to carry on every bike ride covers it. Want a bolt-on version instead? See the C1 Stealth Strap Mount.
