Customer Service

If you have specific questions or concerns about your Diamondback, check first with your local authorized Diamondback dealer. Our dealers are very helpful and are prepared to answer most questions that come up and in a timely manner.

If you have a question or concern that could not be addressed and / or resolved at your local authorized Diamondback dealer, and you live within the United States, give us a call at 1-800-251-8435 and ask for customer service or send us some snail mail using the address above.

We’d also like to be able to keep you informed. You can sign up for Diamondback’s awesome newsletter here.
