Safety Warnings and Safety Information
Installation:
Our products must be installed properly using the appropriate tools and in accordance with the included installation instructions.
If you lack experience, we recommend having the installation performed by a qualified professional or a bicycle mechanic.
Before Riding:
After assembly, the drivetrain must function flawlessly across the entire gear range while the bike is on the assembly stand. The cassette and all associated components must be correctly installed and securely fastened. If the shifting is faulty or any components—such as the brakes—are not securely fastened, the bicycle must not be ridden.
Note on Use:
The cassette and chain are wear parts. During normal use, chains may stretch, the tooth flanks of the sprockets may wear down, and the surface of the cassette may visibly change due to contact with the bicycle chain. This wear and tear, which results from normal use, is due to normal wear and tear and, as such, does not constitute a material defect in the goods, which were free of defects at the time of delivery.
Intended Use:
For use on bicycles in accordance with the product’s technical specifications.
Inspection and Return:
Upon receipt, please first inspect your merchandise for completeness, condition, and compatibility.
You may assemble the product and test its functionality on the assembly stand. If you wish to exercise your statutory right of withdrawal, you should not ride your product beyond what is necessary for inspection, as further use may result in signs of wear and tear and a possible reduction in value. Any compensation for loss of value to be paid will be determined in accordance with statutory requirements.
The consumer’s statutory rights, in particular the statutory right of withdrawal and statutory warranty rights, remain unaffected.
