Manual Carbon saddle

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.

In case of problems with the function of the product, it must not be used. In this case, contact your dealer immediately!


The assembly instructions must be followed! Failure to follow the instructions can lead to defects and injuries! If the necessary tools for correct installation are not available, the installation must be carried out by a specialist workshop using the appropriate tools!
Technical data for the product can be found on our website in the product description and for download in the service area.
Assembly preparation

Before you can start with the assembly, the compatibility of the seatpost must be checked:

  1. Check the compatibility of your seatpost with the dimensions of the saddle rails. The seatpost must be able to accommodate the rails of the saddle without play and show no visible gaps on the clamping parts. The manufacturer of the seatpost often offers separate holders for oval rails. If the seatpost and saddle are not compatible, the saddle must not be used.
  2. Check for proper clamping and the accessibility of the desired riding position by means of a trial assembly. If the clamping system of the seatpost is not compatible with the rails of the saddle, the saddle must not be used.
  3. Check the distance between the screws of the saddle clamping mechanism and the saddle cover. The distance between the screws and the saddle cover must be at least 10mm. If the distance is smaller, the saddle cover may be deformed while driving and the screws may rub on the screws. The rubbing can damage the saddle. If the required distance between the screws and the saddle cover is <10mm, the saddle must not be used.
  4. Check the saddle clamping mechanism for sharp edges. If the clamp is sharp-edged, the edges must be broken with a file before assembly to avoid damage to the saddle rails.
Mounting the saddle

After completing the assembly preparations with a positive result, follow these steps to mount the saddle:

  1. Insert the saddle into the clamp with the tip pointing towards the direction of travel.
  2. Roughly set the desired riding position (inclination and horizontal shift).
  3. Tighten the saddle clamping mechanism according to the instructions for the seatpost. Do not exceed the maximum permissible torque of the saddle!
  4. After installation, check the riding position and readjust if necessary until the desired riding position is reached. Always check that the clamping is in the permissible range for the saddle!
Tightening torques
All screws and connectors must always be mounted with a calibrated torque wrench in compliance with the maximum torques! Non-compliance with the torque specifications can lead to defects and injuries!

Intended use

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.

Please note that our products may only be used in the amateur sector under normal conditions.

The following table lists the permitted use cases of the respective saddles:


Intended use


Roadbike, XC Fully (not for XC hardtail!)

Speedneedle, Speedneedle Marathon, Speedneedle Twenty20

Roadbike, MTB


Roadbike, MTB


Only roadbike!

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.

Maintenance & care

Depending on the conditions of use and the frequency of use, your tune components must be cared for and maintained in order to preserve their function and appearance for a long time.
