Stems and Handlebars
Service Instructions
Congratulations on the purchase of your ENVE Composites Stem and Handlebar!
Please follow carefully the below instructions for correct use. Particular tools are needed and experience is necessary for proper installation, We recommend that all ENVE products be installed by a qualified bicycle technician.
Compatibility
ENVE Composites road and MTB products are compatible with industry standard steerer tube and handlebar diameters. To choose the correct stem, first check the specific diameter of steerer tube and handlebar to be used.
Installation Instructions
Important: For carbon fiber steerers, do not use star-nut type fasteners for headset bearing preload. Instead use an expansion wedge type preload device, available for purchase on our website. Follow specific instructions for expansion wedge.
A: Mounting stem on steerer tube:
1. Ensure that the fork steerer tube is clean and free of burrs or chips.
2. Ensure that the fork steerer tube is cut to the correct length, and that the proper spacers are used to achieve chosen height.
3. With all headset components, fork and spacers installed, slide the stem on to the steerer tube.
4. Install top cap of bearing preload system, and tighten until proper bearing preload is achieved.
5. Important: Tighten stem fixing bolts according to fork manufacturer’s recommendations. ENVE Composite’s maximum allowable torque for the stem fixing bolts is 6Nm. Use fork manufacturer’s recommendations for bolt torque unless the recommendation exceeds 6Nm.
B: Mounting Handlebar on stem:
1. Uninstall the stem face plate.
2. Check that bolt threads have a light layer of grease.
3. Place handlebar between stem and face plate. Thread all bolts in finger tight.
4. Ensure that you have evenly tightened all bolts. Alternate tightening of the bolts using an “X”pattern.
5. Important: ENVE Composite's maximum allowable torque for the handlebar binder bolts is 6Nm.
If a non-ENVE Composites handlebar is used, follow the manufacturer’s specified torque if it does not exceed 6Nm. Torque should not ever exceed 6Nm.
Maintenance
It is the user’s responsibility to examine the product on a regular basis to determine the need for service or replacement. Users should inspect their bicycle and its parts on a regular basis in order to detect damage that may have occurred from normal use. Inspect all parts for damage and wear before each use. Check all fasteners periodically for tightness. Do not over-tighten.
WARNING:
In the event of an accident or crash, all parts should be thoroughly examined by a qualified bicycle mechanic, and any damaged ENVE Composites parts replaced immediately
All damaged parts should be repaired or replaced by a qualified bicycle mechanic before the bicycle is used again. Continuing to use damaged parts may lead to loss of control of the bicycle and cause injury or death
