Derby Rims are designed for the most advanced riders with goals of maximum performance and rider safety including maximum durability. A zero damage rate yearly goal may be impossible, but a zero damage rate is closer each year with advancing experience and technology. In 2017 fewer than 1% of each model of Derby rims were damaged, including DH models. In fact almost all models have been well under 0.5% yearly damage rate for many years. And Derby road rims continue to have a zero damage rate for over 2.5 years since introduced. Although rare, unfortunate damage can occur, and damaged Derby rims are top priority to replace quickly.

When purchased from an authorized Derby Rims dealer, an original retail receipt must have the dealer’s business name, address, and phone number printed on the receipt, and date of sale, the original customer name, and Derby rim model name and wheel build parts. Pictures of the whole wheel having rim damage and a close up picture of the rim damage and rim serial number which is located near the valve hole, are all required. Shipment to Derby Rims of the damaged rim may be required for thorough inspection. The customer is responsible for all shipment costs.
All Derby rims are covered by a lifetime warranty against manufacturing defects for the original owner who had purchased directly from Derby Rims or an authorized dealer.

Derby Rims offers a lifetime rim damage warranty for the original owner who had purchased from Derby Rims or when built into wheels by an authorized wheel builder or bike shop. Damage to a carbon fiber rim's structural integrity is evident when visibly cracked or punctured. Rim surface chips, scratches, and scuffs can occur during use, and are normal wear characteristics not covered by a damage replacement warranty. Please send pictures to Derby Rims if surface chips, scratches, or scuffs are questionable whether structural damage.
Damage has proven to be so rare that Derby Rims sponsors for the original owner a free damage replacement for each rim of a pair purchased together from Derby Rims or built into wheels by an authorized wheel builder, that is determined by Derby Rims to be structurally damaged within the first year of purchase date; and during the second year the replacement is $145 for most Derby rims or $185 for the 27.5x45i and 29x40i plus tire rims for each original rim. Otherwise, if the original customer suffers a structurally damaged rim, the replacement price is $245 for most rims, or $285 for the 27.5x45i and 29x40i plus tire rims. The customer is responsible for all shipment costs.
The Lifetime Damaged Rim Replacement Warranty is transferable by resale or gift to a secondary owner, or while loaned to another rider by any current owner. To qualify for a damaged Derby rim warranty priced replacement by any rider who was not the original owner, a picture of the original owner's receipt of purchase is required with pictures of damage and serial number as described fully above for all warranty requests. The damaged Derby rim replacement cost for a rider who was not the original owner is $295 for most rims, or $345 for 29x40i and 27.5x45i rims. The customer is responsible for all shipment costs.

Derby Rims are warrantied for use with no greater than the maximum tire pressures listed on the Technical page of DerbyRims.com.
Derby Rims are warrantied for use with rim tape designed and clearly labeled specifically for use in bicycle rims.
Derby mountain rims can normally can be used with one round of adhesive rim spoke hole sealing bicycle rim tape within the center channel, two rounds of tape is recommended for DH rims or rims used in hot climates.16-18mm or ¾ inch maximum wide rim tape must be installed for Derby 30i and 35i rims, or 24mm or 1 inch maximum wide rim tape must be installed for Derby 40i and 45i plus tire rims (Orange Seal rim tape is recommended). Derby 25i, 23i, and 22i rims for paved or gravel road can be used with two rounds of 12 to 14mm maximum wide adhesive rim spoke hole sealing tape within the center channel (Stan's 12mm yellow rim tape is recommended).
Derby rims can be used with inner tubes, or tubeless with liquid tire sealant, having 40mm minimum length stems. For tubeless sealant use, it can be helpful to seat the beads with a common floor pump if additional rounds of rim tape are added (Orange Seal tubeless tire sealant is recommended). When riding tubeless with sealant, ride with caution to observe the reaction of your tires and rims, and frequently check for loss of tire pressure while the sealant is setting up during the first few days. Due to the variety of tires, some may work much better tubeless with sealant than others. If your tire pressure drops too low there is a risk of severe rim impact. The plastic rim strip and sealant system allows the use of standard, tube-type tires, to be used in a tubeless manner. It should be noted that some tube and tubeless tires were not designed to be used with sealant and doing so may void the tire's warranty.
Derby Rims is not responsible for any damage to the tires or Derby Rims and/or any injury or liability resulting from the use of rims sold by Derby Rims or tires mounted on rims sold by Derby Rims. The terms of the Derby Rims Lifetime Warranty and Disclaimer are agreed upon any purchase and by any rider of Derby Rims.
