FAQs
Is this bearing sold as a pair?
No, the Hope Headset Cartridge Bearing is sold individually.
Does this fit a straight 1 1/8 inch head tube?
No, this is specifically for 1.5-inch tapered headset systems with a 52mm outside diameter.
What does the 45 by 45 degree angle mean?
This refers to the chamfer angle of the inner and outer race of the bearing, which must match your headset cup and compression ring.
Do I need special tools to install this?
It is highly recommended to use a headset press to ensure the bearing is seated perfectly square in the frame.
Should I grease this bearing before installation?
Yes, a light coating of high-quality waterproof grease is recommended to prevent corrosion and facilitate smooth movement.
Troubleshooting
Steering feels 'notchy' or indexed
The bearing may be worn or the headset is adjusted too tightly. Inspect the bearing for pitting and ensure the preload is set correctly.
Headset develops play (wobble)
Check that the headset top cap bolt is tightened to the manufacturer's torque specifications and that all spacers are properly seated.
Bearing does not fit the frame cup
Verify the outside diameter of your headset cup. This bearing requires a 52.0mm OD. If your frame requires a different size, it will not fit.
Pros and Cons
Pros
- High-quality construction ensures longevity
- Precision-engineered for smooth steering movement
- Direct replacement for standard 52mm OD headset cups
- Durable design withstands off-road and road cycling demands
Cons
- Not universal; only fits 1.5-inch tapered headsets with 52mm outer diameter
- Requires specific tools for headset removal and installation
- Sold individually, so both upper and lower bearings may need separate orders if replacing an entire set
Setup, Compatibility & Care
Before installation, ensure your existing headset cup is clean and free of debris. Always use a proper headset press tool to install new bearings to prevent damaging the cartridge or the frame.
Compatibility
- Steerer Tube: 1.5-inch tapered
- Bearing Angle: 45x45 degree
- Outside Diameter: 52.0mm
Care Instructions
- Use high-quality waterproof bike grease during installation.
- Inspect the bearing seals periodically for signs of grit or contamination.
- Avoid using high-pressure water sprayers directly on the headset area during cleaning, as this can force debris past the seals.
