WARNING: Installing this bicycle product requires expert in-depth knowledge of bicycle mechanics and professional-grade tools. If you do not have the proper tools or knowledge to perform this installation, please take your bicycle to your local bicycle dealer. Failure to appropriately install this product may lead to component failure, resulting in serious injury or death.
We recommend that you have this product installed, adjusted and maintained by a professional bicycle mechanic.
- Chromag OSX, Acute, Acute Flat, and FU40 bars are made from 7000 series alloy.

- OSX, Acute, Acute Flat, FU40 and Cutlass bars are 31.8mm in diameter. BZA bars are 35mm in diameter.
- BZA series handlebars are 35mm clamp only
- OSX, Acute, FU40 and Cutlass series are 31.8 clamp only
Stem Compatibility: WARNING – IMPORTANT!:
- There are many stems on the market today. Some are better than others. We have determined that some stems can reduce the strength and lifespan of the handlebar. As a result, our first recommendation with any Chromag bar is to use a Chromag stem.
- Our Chromag Carbon bars should ONLY be mounted with Chromag stems. Using another stem is not recommended, may lead to component failure, and will void the warranty.
***WARNING !! Installation and service by a qualified mechanic is always recommended***
WARNING: The rider assumes all risks upon installation and use of Chromag handlebars. Improper installation will void the warranty and may lead to component failure or damage, resulting in serious injury or death, as well as damage the bar which could cause serious injury or death.
Carefully inspect the bar for any damage that may have occurred during shipping and handling. Do not fit or use the bar if it appears to be damaged. Consult your local bike shop or Chromag directly if you have any concerns.
Inspect the stem for any sharp edges, or burrs that could come in contact with the bar. Chromag stems are chamfered in the contact areas. If the stem has a sharp edge or burr, it may be advisable to use some light sandpaper to remove it. Consult your local bike shop / mechanic.
Before installing, all surfaces should be clean and free of dirt or grease. For carbon handlebars, it is recommended to use carbon friction paste between contact areas.
When tightening the stem bolts, be sure to do so in an even manner, following a crisscross pattern, torqueing each bolt a small amount towards the recommended torque value.
Be sure to follow the requirements for stem faceplate gap when installing. For example, Chromag stems are designed to have an even gap at both top and bottom of the stem. Some stems are designed to have a closed gap at one side. Note that uneven or incorrect tightening can damage or lead to premature damage of the handlebar. Refer to stem guidelines for torque values however if they are higher than the handlebar values always refer to the lower value.
For all carbon bar models (Cutlass and BZA), the max torque value for stem installation is 6NM. For controls (shifters, levers, grips etc) max torque value is 4NM For all alloy bar models (Acute, FU40, OSX) the max torque value is 6NM.
For all alloy bar models (Acute, FU40, OSX) the max torque value is 6NM.
Mount all levers, brakes and grips with care. Ensure that component clamps have been loosened before installing and do not force or twist components onto bar (which could cause scratching). Inspect all component clamps for burrs and sharp edges before installing. Always mount components within the non tapered area of the bar. Do not install components towards the center of the bar where the taper begins.
Use bar-end plugs or grips with closed ends to reduce damage to the handlebar and injury to the rider. NOTE: hammer-in style bar-end plugs should never be used with bar end plugs.
Bar ends and plugs:
Chromag bars are not intended to be used with bar ends. Bar ends can be installed on alloy models. Bar ends CANNOT be installed on carbon models. Installation of bar ends on carbon bars will void the warranty.
Bar-end plugs that need to be hammered into the bar are NOT to be used on carbon models.
Lock on style grips can be used on alloy and carbon models provided they are tightened within torque specs.
Chromag bars are designed with appropriate width for the intended application. However, we understand that everyone is different, so if you need to cut down your bars make sure you do it a correct and safe way
Always double check measurements before cutting. Measure twice.
A cutting guide is recommended
remove rough edges and burrs with a fine file or sandpaper after cutting.
Wrapping tape around the bar can limit chips, splinters etc. A carbon-specific blade is recommended however a regular hacksaw (we recommend 32tpi) can also be used – with care. Note that aggressive cutting can cause a carbon bar to splinter. Cut slowly.
Care and Use:
Keeping handlebars clean and dry will help preserve the quality of the surface finish.
Regularly check bolt torques (always tighten all bolts evenly).
Avoid storing and travel situations where the handlebars can be scratched by other bikes or foreign objects. Deep scratches can lead to cracks and it is advisable to replace handlebars that have been compromised.
Inspect bars regularly for scratches and gouges, cracks or discoloration, particularly after a crash. If you are unsure, refer to your local bike shop mechanic with any questions. Never attempt to bend-back or “fix” the handlebar after a crash.
Always replace handlebars after significant impact, crash and or a crash resulting in any kind of visual damage. Do not attempt to straighten a bar or stem that has twisted in a crash without first loosening the bolts. As bars cannot be repaired following an impact, bars should be replaced immediately.
Depending on the regularity and severity of use, your bars only have a minimum service life of one year. It is crucial when used in high frequency use scenarios (100+ days/ year, regular lift access riding, professional, semi-professional training and racing) that your handlebars be replaced after one year.
Special note to lift access riders: Riding lift access bike parks can increase the frequency of use on our products tenfold. If you are a regular lift access rider it is imperative that you replace your bars yearly.
Aside from cutting the ends, do not attempt to modify any Chromag handlebar.
Use carbon friction past with carbon handlebars or clamped carbon components.
Handlebars are only compatible with the corresponding diameter stem. Do not shim, modify or try to use with no-corresponding sizes. Carbon handlebars should only be used with Chromag stems.Lifespan:
Lifespan varies depending on type of use, rider weight and frequency of riding. For high level use including semi-professional or professional training and competition, hi-frequency enthusiast, lift access, shuttle access, all handlebars must be replaced after 1 year of use.
