If you received a faulty product, please remember that Kogel and R Squared Industries strives for a best-in-industry warranty.

How does it work?
Before you send anything back to our office, it would be good that we know it’s coming. Call, email, instant message and R Squared Industries will provide you with return instructions. We are not the types to waste time, so returns are typically processed quickly and we will contact you.

Lifetime Warranty applies to original owners only (valid proof of purchase required). If one of our F3 products fails due to a manufacturing defect we will replace it without charge at our discretion. Only original, unaltered and unmodified items and craftsmanship are covered. This warranty does not cover crash damage, improper care, improper installation or negligence.

F3 design and manufacture products to very strict tolerances and quality expectations. Post manufacturing products are inspected and assembled – by hand. We understand that crashes and mishaps happen and would gladly like to hear the stories. We also have very keen eyes when reviewing our babies – we can identify scratch marks made by angry pliers, damage done by the winging-it installation method. Detailed instructions & videos can be found online and on the website and packaging for good reason.

Warranty does not cover damage to phones, computers, lights, or cameras, caused by improper installation, or improper use, or a failed F3 Cycling part. User assumes that risk. Sales tax, shipping on returns, VAT etc are not covered by R2 Industries.

If the glove you have purchased does not fit or isn’t right for you then you can return in original packaging for a full refund.

Please note that any returns requested for refund must have the garments in resellable condition: hang tags and packaging must be present and undamaged.

If you decide to trail test the gloves, they are no longer resellable and we cannot accept returns or exchanges. Nobody likes getting used gloves in the mail!
