Specialized Bicycle Owner's Manual - Appendix A Supplement - 2021 Rider/Bike Weight Limits and Terrain Conditions

Q: What is Appendix A supplement used for?

It helps riders determine whether a bike is suitable for intended use based on the combined Rider Weight and Cargo Weight.

Q: How do Structural Weight Limits affect allowed Cargo Weight?

As rider weight approaches the bike’s Structural Weight Limit, the permissible Cargo Weight may be reduced or become zero.

Q: How is the maximum allowed Cargo Weight determined?

Find the bike model’s Structural Weight and Cargo Weight limits, determine Rider Weight (including riding gear), then subtract Rider Weight from the Structural Weight Limit to get the allowed Cargo Weight, up to the model’s Cargo Weight Limit.

Appendix A supplement provides annual, model-specific guidance for riders to judge whether a Specialized bicycle fits intended use based on the combined Rider Weight and Cargo Weight. It explains how Structural Weight Limits relate to Cargo Weight limits, including cases where allowable cargo must be reduced as rider weight approaches the structural limit. The document describes required steps to determine maximum structural weight for a chosen model and includes warnings about risks of exceeding structural and cargo limits.

SPECIALIZED BICYCLE OWNER'S MANUAL APPENDIX A SUPPLEMENT 2021 RIDER/BIKE WEIGHT LIMITS AND TERRAIN CONDITIONS INTRODUCTION This Appendix A manual supplement is designed as an annual addition to the Appendix A section found in the Specialized Bicycle Owner’s Manual. This appendix is designed to help the rider determine if a bike is suitable for the intended use and the combined Rider Weight and Cargo Weight. Each bike model has an intended use and is designed and tested to support a Structural Weight Limit, which includes a Cargo Weight Limit. As the weight of the rider approaches the Structural Weight Limit of the bike, the allowable Cargo Weight might be reduced. For example, a bike may have a 55lb Cargo Weight Limit, but if the weight of the rider is too close to the bike’s Structural Weight Limit, the rider may only be allowed to carry a smaller amount of cargo or no cargo at all. See the following page for a model-specific example and graphs. STRUCTURAL WEIGHT LIMIT RIDER WEIGHT CARGO WEIGHT 0 25 50 75 100 125 150 175 200 225 250 275 300 UNDERSTANDING WEIGHT LIMITS FRAME STRUCTURAL WEIGHT LIMITS Structural Weight Limits for each bike are determined by Specialized through extensive lab testing, and are listed in the Bike Model, Structural Weight Limit and Cargo Weight Limit Tables. | | STRUCTURAL WEIGHT LIMIT | The maximum Total Weight (rider and cargo) a bike is designed and tested to support structurally. | | --- | --- | --- | | | RIDER WEIGHT | The weight of the rider in riding gear (e.g. , jacket, helmet cam, hydration pack, helmet, etc.) . | | | CARGO WEIGHT | The weight of any additional accessories (e.g., panniers, front/rear racks, saddle bags, handlebar bags, baskets, etc.) not accounted for in Rider Weight. | | | CARGO WEIGHT LIMIT | The maximum Cargo Weight a bike has been designed and tested to support structurally. | | | TOTAL WEIGHT | The sum of Rider Weight and Cargo Weight. | WARNING! Failure to follow these instructions and exceeding the specified Structural Weight and Cargo Limits may impair the structural integrity of the bicycle and may cause serious personal injury or death. For riders at the Rider Weight Limit, you may not be able to carry cargo if the Structural Weight Limit is exceeded. DETERMINING MAXIMUM STRUCTURAL WEIGHT LIMITS 1. Determine the bike model in the Structural Weight Limit Table (see page 7) . 2. Look up the Structural Weight and Cargo Weight Limits of the bike model. 3. Determine the Rider Weight, which includes all riding gear. 4. Determine the Cargo Weight, which includes the weight of any additional accessories. 5. Subtract the Rider Weight from the Structural Weight Limit. The result is the amount the rider is allowed for Cargo Weight, up to the Cargo Weight Limit prescribed for the bike model. EXAMPLE: HARDROCK (Structural Weight Limit = 300lb / 136kg. Cargo Weight Limit = 55lb / 25kg) STRUCTURAL WEIGHT LIMIT RIDER WEIGHT CARGO WEIGHT 0 25 50 75 100 125 150 175 200 225 250 275 300 Rider Weight (255lb) + Cargo Weight (20lb) =275lb Total Weight ok | | | | --- | --- | | STRUCTURAL WEIGHT LIMIT
