Hubs front & rear
Updated by tune
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.
Assembly of hubs
The basic structure of our hubs and freewheels can be understood using exploded views:
Separate instructions for assembling and disassembling the hubs explain the procedure for maintenance work:
Lacing of hubs
The geometrical data required for lacing can be found in the spoke length calculator on our website.
The max. spoke tension of the hub must be observed when lacing. The values for our hubs can be found on the respective product page on our website.
Our freewheel bodies are made of aluminum and can therefore show notches when used with cassettes made of individual sprockets. These notches pose no reason for complaint and can be removed with a file. Stuck sprockets can be removed using two chain whips.
The cassette must be installed according to the manufacturer's instructions. When inserting the locking ring, ensure that it is correctly seated in the thread. To do this, make the first turns by hand.

Assembly brake disc
The brake discs must be installed according to the manufacturer's specifications. The max. tightening torques can be found in the section on tightening torques.
The following applies for 6-hole brake discs:
- Always tighten screws crosswise.
- Remaining screw locking compound from prior assemblies must be removed from the thread of the hub before assembly!
- The screws for fastening the brake disc should be secured against loosening with a medium-strength threadlocking compound (e.g. LOCTITE® 243).
The following applies for Centerlock brake discs:
- The hubs are delivered without a lockrings. They must be purchased separately!
- Screw in the locking ring by hand to avoid jamming in the thread. If the ring can only be screwed in with force, do not turn it any further and check that it is correctly positioned in the thread!
- After tightening the locking ring, the brake disc must not have any axial play! If there is axial play, repeate the assembly or contact your local dealer for support!

Specialized lubricants are used in our hubs. The use of incorrect lubricants can impair the function and lead to defects. We recommend the use of the following lubricants:
Pawl seats of the freehub body
MOLYKOTE® G-Rapid Plus Paste
Drive ring, inner bearing rings
MOLYKOTE® Longterm 2 Plus Extreme Pressure Bearing Grease
Labyrinth seal between hub body and freewheel body
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.
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.
