Product Information
Full details
The Race Face Atlas 35 Stem is built for gravity-oriented riders, including all-mountain and downhill enthusiasts, who prioritize steering precision and structural integrity. Featuring a 35mm clamp diameter, this component delivers exceptional stiffness and reliable performance under heavy load, though its aggressive design and weight are optimized more for durability than for weight-conscious XC racing.

FAQs
Is this stem compatible with 31.8mm handlebars?
No, the Atlas 35 is specifically designed for 35mm diameter handlebars only.
Can I use this stem with a carbon handlebar?
Yes, the faceplate is specifically designed to distribute pressure evenly to prevent stress risers, making it ideal for carbon bars.
What is the weight of the 50mm version?
The 50mm length weighs approximately 160 grams.
Does the stem come with installation bolts?
Yes, it includes all necessary hardware for mounting to your steer tube and handlebar.
How often should I check the bolt tension?
It is recommended to check the torque on all bolts before every major ride or at least once a month if riding frequently.
Troubleshooting
Handlebar slipping or rotating in the clamp
Ensure the faceplate bolts are tightened to the specific torque rating in a cross-pattern. Clean the handlebar and stem interface with isopropyl alcohol to remove any grease or debris.
Creaking sounds coming from the cockpit area
Remove the faceplate, clean the contact surfaces, apply a light coat of carbon paste (if using carbon bars) or grease (if aluminum), and reinstall ensuring even torque distribution.

Setup, Compatibility & Care
Installation of the Atlas 35 stem requires a high-quality hex key set and a calibrated torque wrench to ensure proper fastener tension. Always apply a thin layer of grease to the bolt threads before installation. When tightening the faceplate, follow a cross-pattern sequence to ensure even clamping pressure, and never exceed the manufacturer's specified torque limits. For care, keep the steer tube area clean of debris and periodically check that all bolts remain at the factory-recommended torque settings. This stem is strictly compatible with 35mm clamp handlebars and 1-1/8 inch steer tubes.
