What is the warranty?

Coefficient Cycling warrants each new Coefficient Handlebar against defects in workmanship and materials for a period of two full years from date of purchase. This warranty is strictly limited to the replacement of a defective handlebar. This warranty applies only to the Coefficient bar's original owner and cannot be transferred. Removal of sticker with serial number voids the warranty.

Warranty does not cover normal wear-and-tear, incorrect assembly, or any damage caused by the partnering with incompatible components or attachment of accessories. Warranty does not apply to damage or failure due to accident, abuse, misuse or neglect. In case of handlebar replacement, labor costs for switching handlebars and shipping costs are not covered by the warranty.

Warranty claims must be made through authorised Coefficient retailers or directly with Coefficient Cycling.

Do you have a crash replacement policy?

Yes we do. Sometimes accidents happen. You might bin it at a crit race or your roof rack has a bad day... we can offer you 30% off a new bar PLUS we'll throw in a new pack of bar tape (if available). Get in touch and we'll issue you a code to use on site.

Do you ship internationally?
