FAQ & Warranty

How do I install a Coefficient handlebar?

Each Coefficient Handlebar is shipped with comprehensive installation instructions. We recommend that only a qualified bike mechanic install this handlebar. Please follow the installation instructions very carefully. An improperly installed handlebar can lead to damage to the product (nullifying its warranty) or damage to your bike.

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.
