Safety Instructions – Bicycle Rims

We would like to thank you for your trust in our products. However, your safety is our highest priority. Therefore, we strongly recommend that you read these safety instructions carefully before using the rim.

General Information

Rims are subject to wear over time. Damage may occur due to environmental influences, mechanical impact, material fatigue, or normal wear.

If you detect any cracks or significant deformation, stop using the rim immediately and replace it. Continuing to ride with a damaged rim can result in serious injury or death.

Replacing a rim requires advanced bicycle mechanical skills. We strongly recommend that this work be carried out by a professional bicycle mechanic. If you are not a professional bicycle mechanic, any work performed is at your own risk.

Tire Bed

The nipple holes in the tire bed can weaken the structure of the rim. Cracks may originate from these holes. Please also inspect the area underneath the rim tape.

Nipple Bed

The load force transmitted by the spoke nipples to the nipple hole area can cause material fatigue. As a result, cracks may develop.

Rim Hooks

Mechanical impacts may deform the rim hooks. If this occurs, a secure tire fit can no longer be guaranteed.

Do not attempt to repair a deformed rim hook using pliers or by bending it back into position. This can compromise structural integrity and safety.

Limitations

Always respect the maximum spoke tension, maximum system weight, and maximum tire pressure specified on the rim.

Intended Use

Please follow the intended usage guidelines specified on our website.

Inspection Intervals

For your safety, any significant deformation of the wheel may be caused by one of the issues described above. In such cases, inspect the tire bed, nipple bed, rim hooks, sidewalls, and spoke tension carefully.

The following are the minimum recommended inspection intervals to ensure safe operation:
