Product Information

Full details

The Race Face AEffect 35 Stem is designed for cross-country and trail mountain bikers seeking the stiffness and performance advantages of the 35mm handlebar standard without a premium price tag. Featuring a precision forged and machined alloy construction, this stem offers an ideal strength-to-weight ratio for aggressive riding; however, users should ensure their current handlebar diameter is 35mm, as this model is not compatible with standard 31.8mm bars.

Extended Product Information

FAQs

Can I use this stem with a 31.8mm handlebar?

No, this stem is specifically engineered for 35mm handlebars and will not safely secure a 31.8mm bar.

What is the weight of this stem?

While weight varies slightly by length, the AEffect 35 is designed as a lightweight option for trail and XC builds.

What is the stack height?

The stack height for this stem is 39mm.

Is this suitable for downhill racing?

This stem is optimized for XC and Trail riding. While it is very strong, Race Face offers dedicated gravity-specific stems for downhill use.

Does this come with a top cap?

Typically, the stem is sold as a standalone unit; you should reuse your existing headset top cap and bolt.

Can I flip the stem to adjust height?

Yes, the stem is reversible and provides a +/- 6-degree rise/drop.

Troubleshooting

Handlebars slipping or rotating under load

Check that all four faceplate bolts are tightened to the recommended torque specification and ensure the bar diameter is exactly 35mm.

Creaking noise from the cockpit

Remove the faceplate, clean the contact areas of the stem and bar with a dry cloth, and ensure no grit is trapped between components.

Steer tube feels loose after install

Ensure the top cap is tightened to apply proper preload to the headset bearings before tightening the side bolts on the stem.

Pros and Cons

Setup, Compatibility & Care

To install the AEffect 35, ensure your bicycle fork has a standard 1 1/8-inch steer tube and that your handlebars are exactly 35mm in diameter.

  1. Loosen the faceplate bolts to remove the front clamp.
  2. Center your handlebars and replace the faceplate.
  3. Tighten the bolts in an 'X' pattern to ensure even pressure, typically to 5-6Nm (always refer to specific manufacturer torque ratings).
  4. Ensure the stem is properly aligned with the front wheel before fully torquing the steerer tube clamp bolts.

For care, periodically check the bolt tension as part of a standard maintenance schedule, especially after the first few rides. Clean the handlebar and stem contact points with a dry cloth to remove debris that could cause creaking.
