Product Overview
The Eufab frame holder is designed to securely attach a bicycle to the U-bracket of a bicycle carrier. It is intended for private use and is not suitable for commercial applications. The device must not be used by children or individuals without the necessary specialist knowledge.

Technical Specifications
The holder is compatible with U-bracket diameters of 25 mm and 30 mm, and bicycle frame diameters ranging from 30 mm to 60 mm. Two models are available: the 11230 (approx. 10.5 cm length, 0.260 kg) and the 11231 (approx. 30 cm length, 0.340 kg).
Installation
To install the holder, open the pipe clamp by completely unscrewing the knob screw. Select the appropriate rubber insert (25 mm or 30 mm) based on your bicycle carrier's U-bracket diameter and place it around the bar. Position the pipe clamp over the insert, press it together, and insert the knob screw through both holes. Screw the frame holder onto the knob screw thread. Finally, secure the bicycle frame using the integrated tension belt and tighten the knob screw firmly.
Safety and Maintenance

Before driving, ensure the bicycle is secured according to the carrier's instructions, including the use of tension belts and safety straps. Clean the holder with a soft, slightly moist cloth and a mild cleaning agent; avoid solvents, petrol, or aggressive cleaners. Ensure no liquids enter the tube of the holder.
