Knog Oi Classic (⌀31,8mm) Adapter Bike Computer

Transform your Knog Oi Classic (Large) bell into an inconspicuous under-head mount! With this minimalist adapter, you can neatly and aerodynamically attach the bell directly under your existing bike computer mount (e.g., Garmin/Wahoo Out-Front Mount) on your road bike.

This ensures an absolutely clean cockpit and keeps the handlebars free for your hands or aero positions.

📐 Technical Details & Dimensions

• Clamping Diameter: 31.8 mm
• Height: 15.2 mm
• Mounting: 2x through-holes for M3 screws

🛠 Printing & Assembly Instructions

⚠️ Important note on the holes: > The two M3 through-holes are deliberately sized relatively tight in the design to ensure maximum stability. Depending on printer calibration and material shrinkage, it is recommended to carefully re-drill the holes before assembly with a 3mm drill bit by hand or with a cordless drill.

• Material Recommendation: For use on a road bike (due to UV radiation and vibrations), I recommend PETG, ASA, or ABS. While PLA works, it can soften in direct sunlight on hot summer days.
• Infill: At least 30% - 50% (preferably Grid or Gyroid) for sufficient clamping stability.
• Orientation: For the best stability of the tabs, ideally lay the part flat on the print bed.
