Product Information
Full details
The FSA SMR Series Handlebar Stem is designed for cyclists seeking advanced, integrated cable management solutions. Its primary benefit is a cleaner cockpit and improved aerodynamics by routing cables internally. A potential caveat is the specialized nature of internal routing, which may require specific frame compatibility and a more involved setup process compared to external cabling.

FAQs
What is the main advantage of the SMR system?
The SMR system's main advantage is integrated cable routing, which cleans up the cockpit, improves aerodynamics, and enhances the bicycle's aesthetics.
What handlebar diameter does this stem support?
This stem supports a standard 31.8mm handlebar clamp diameter.
Is this stem compatible with any bike frame?
No, this stem is designed for frames specifically engineered to accommodate FSA's SMR integrated cable routing system. Always check your bike's compatibility.
Can I use this stem with a standard headset?
It is recommended to use this stem with FSA's compatible SMR headset for optimal integration. Compatibility with standard headsets may be limited and require specific setup considerations.
How do I clean the stem without damaging it?
Use a soft, damp cloth and mild soap if necessary. Avoid harsh chemicals or abrasive materials that could scratch or degrade the finish.
What does 'AL6061 CNC Machined' mean?
It means the stem is precisely cut from a solid block of AL6061 aluminum alloy using Computer Numerical Control (CNC) machines, ensuring high accuracy, strength, and a premium finish.
What is the fork clamp height?
The fork clamp height refers to the vertical dimension where the stem clamps onto the bicycle's steerer tube, which is 33.5mm for this model.
Troubleshooting
Difficulty routing cables internally
Ensure you are using a compatible frame and headset designed for SMR routing. Use a guide wire if necessary and work slowly to avoid kinking cables.
Stem bolts won't tighten correctly
Verify you are using the correct size Allen key and that the threads are clean and free of debris. Do not overtighten; use a torque wrench to adhere to specifications.
Noise or creaking from the stem/headset area
Check all mounting bolts (stem to steerer, stem faceplate to stem body) and ensure they are torqued correctly. Reapply a thin layer of quality bike grease to the steerer tube and stem clamping surfaces.
Limited steering angle after installation
Confirm that cables are not excessively tight or caught on the frame. Ensure headset spacers and top cap are correctly installed and adjusted, allowing for full steering rotation without binding.
Pros and Cons
Pros
- Significantly improves cockpit aesthetics by hiding cables.
- Enhances aerodynamic performance by reducing cable drag.
- Durable construction due to AL6061 CNC machining.
- Provides a secure and rigid connection to the handlebar.
Cons
- Requires compatible frame and headset for full integration.
- Installation can be more complex than standard stems.
- Limited adjustability for cable routing compared to external systems.
- May add slight weight compared to minimalist external routing solutions.
Setup, Compatibility & Care
Setup: Ensure your bicycle frame and headset are specifically designed for integrated cable routing systems like FSA's SMR. Consult your bike manufacturer's documentation for compatibility and routing paths. Installation typically involves routing cables through the stem and into the headset assembly, requiring precision and patience. Refer to the FSA technical manual for detailed installation steps.
Compatibility: This stem features a 31.8mm handlebar clamp diameter and a 33.5mm fork clamp height. It is designed to work with FSA's SMR system components. Compatibility with non-SMR headsets or frames may be limited or require specific adapters.
Care: Clean the stem regularly with a soft, damp cloth. Avoid abrasive cleaners or solvents, which can damage the finish. Periodically check that the stem bolts and handlebar clamps are securely tightened to the manufacturer's torque specifications using a torque wrench.
