Manual Porteur GPS-mount
Thank you for purchasing tune products! Our products are designed and manufactured to the highest standards. This manual informs you about the proper handling and care of our products.
Our components are high-end parts and must always be assembled and used in accordance with the user manual. Please read this manual carefully and follow the instructions. If you are not confident with the assembly, please contact your dealer.
Construction of the Porteur
The Porteur comes pre-assembled and is mounted to the stem. The following exploded view shows the construction of the Porteur in its different variants: Exploded view Porteur
Mounting the Porteur to the stem
Follow the steps below to mount the Porteur:
- Loosen the handlebar clamping screws on the stem.
- Remove the lower two clamping screws. These are replaced by the M5x23mm screws enclosed with the Porteur.
- Thread the M5x23mm screws through the porter and the front plate of the stem and slightly tighten by hand.
- Tighten the handlebar clamp screws crosswise according to the torque specification. Also refer to the instructions for the stem: Geiles Teil 4.0
- Check the size of the gap on the top and bottom of the handlebar clamp and ensure that the gap size is equal. Repeat assembly if the gap dimensions are different!
- Insert your GPS device into the Porteur by using the quarter-turn-mount.
- Mount the Di2-junction-box or GoPro accessories in the bracket on the underside as required.

Our products are designed and tested according to the current standards, which define the safety requirements and test methods for mountain bikes off-road and racing bikes for amateur use on public roads. In both cases, the standards for bikes with adjustable saddle height with a minimum saddle height of 635mm apply.
The standards mentioned do not apply to special types of bicycles such as tandems or bicycles which are used for special applications such as tough competition, stunts or acrobatics.
The standards also do not apply to bicycles with a saddle height ≤ 435mm and a saddle height between 435mm and 635mm.
Storage & transport
When storing or transporting tune components for a longer period of time, follow these guidelines:
- Components must be stored and transported at a temperature of 15-30°C and max. 70% relative humidity.
- Components must not be exposed to direct or indirect sunlight. Ideally, storage and transport take place in a dark place or covered.
- Avoid large temperature fluctuations, e.g. in a car parked in the sun. Torques must be checked again after storage or transport with large temperature differences to ensure proper function.
- Components must be cleaned and checked for proper function before storage. Before the next operation, a new check for functionality must be carried out.
- Wheels should be stored and transported with the tyres fitted. The mounted tyre reduces the spoke tension and thus the load on the hub flange.
- Do not hang up carbon rims or entire bicycles, as the point load can cause permanent damage to the rim.
- Do not hang up stored bicycles by the saddle to reduce the load on the saddle and seat post.
