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. PLEASE NOTE - do not use carbon paste to mount your bar on your stem.
How do I know which size handlebar to get?
Order the exact same size bar you currently use – assuming it’s measured center-to-center at the hoods and you’re pleased with your current size. For our specs, visit the page below and scroll to the bottom:
RR bar: https://coefficientcycling.com/collections/all-products/products/rr-road-race-handlebar
AR bar: https://coefficientcycling.com/collections/coefficient-handlebars/products/ar-all-road-handlebar
As for the rest of your setup, keep the same size stem and stack height.
What is the difference between RR and AR handlebars?
BOTH handlebars are designed to be very ergonomic and are expert at handling both road and off-road (road, gravel). They also have a thumb indent that adds comfort and control when in the drops.
What sets them apart are:
Tops of bars – AR is ovalized, RR is more flattened
RR can be routed externally, partially internal (enter at levers, exit before middle junction) or fully internal (enter at lever and exit directly into stem). AR can be routed externally or fully internal.
RR is UCI-legal and best suited for racing (road, gravel, cyclocross, fast group rides)
RR has built-in computer mount
AR has space on both sides of the bar for mounting computers, lights, bells, etc. With the RR, to attach a light you’ll need our custom GoPro mount which allows for mounting accessories on the underside of the computer mount.
What are the computer mount screw specs?
Hex Drive Flat Head Screw with 90° Countersink Angle: M4 x 0.70 mm Thread, 8 mm long
What is the GoPro bolt specs?
The pivot/knuckle screw is M5x1x20mm button head. The mounting screws are M4x0.8 flat head.

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 authorized 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 with us so we can arrange this for you.
Do you ship internationally?
We ship to most countries, but if you find we are not set up to ship to your country please contact us so that we may help.
