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.
Concstruction of the FusePlugs
The FusePlugs are delivered pre-assembled. Only the desired O-ring has to be added for assembly. The following exploded view shows the construction of the FusePlugs: Exploded view FusePlugs
The bar plugs consist of the following components:
- 2x plastic nut
- Counter cone
- Silicone tube
- Cone - in different colors depending on the version
- O-ring - Roadbike: 19x3mm
- Slotted countersunk plastic screw
- Alternative: O-ring - MTB: 19x4mm
Mounting the FusePlugs to your bar ends
The FusePlugs were developed to protect carbon handlebars in the event of a fall with the elastomer buffer. Similar to the crumple zone in modern vehicles, the FusePlugs were designed in such a way that they absorb the forces in the event of a fall and thus protect the handlebars from damage.
Follow these steps to mount the FusePlugs to your bar ends:
- Mount the O-rings of the required size on the fuse plugs.
- Insert FusePlugs into the bar ends. If the bar end is too narrow, the slotted screw in the FusePlug can be slightly unscrewed to reduce the diameter of the plug.
- Tighten the countersunk screw with a suitable screwdriver ¼ to a maximum of 1 turn
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.
