FAQs
Are these grips suitable for all handlebar types?
These are designed for standard flat-bar handlebars found on hybrid, mountain, and trekking bicycles.
How do I know if I need the Large size?
The Large size is recommended for riders with larger glove sizes or those who prefer a fuller feel in their palm, whereas the Small size is better for smaller hands.
Can I use these with bar ends?
The GP1 design is generally intended for use without bar ends, though they are compatible with most standard setups that have sufficient bar length.
Does the cork material wear out quickly?
The cork composite is highly durable. While it may develop a light patina over time, it is designed to withstand thousands of miles of use.
Is the cork material slippery when wet?
No, the cork composite is chosen specifically because it maintains excellent grip and texture even in damp or humid conditions.
Are these grips compatible with grip-shift shifters?
These are the standard GP1 grips. If you have grip-shift style shifters, look for the specific 'Nexus/Rohloff' or short-version variants.
Troubleshooting
The grip rotates on the handlebar while riding.
Ensure the locking clamp bolt is tightened to the recommended torque. If it continues to slip, check that no grease or debris is present on the handlebar surface under the clamp.
Wrist pain persists after installation.
Re-adjust the angle of the grip. The wing should be positioned to provide a flat platform for your palm while your wrist remains in a neutral, straight line.
Pros and Cons
Pros
- Significantly reduces hand numbness and wrist strain
- Breathable and tactile natural cork material
- Environmentally conscious manufacturing and materials
- Secure locking clamp prevents rotation
- Excellent build quality for long-term durability
Cons
- Requires careful adjustment for the correct ergonomic angle
- Large size may be too bulky for smaller hands
- Light-colored cork may show dirt faster than black rubber grips
Setup, Compatibility & Care
Installation is straightforward but requires a 4mm hex key to secure the locking clamp.
- Placement: Slide the grips onto the handlebar until they reach the end.
- Angle Adjustment: Rotate the grip so the wing portion is level with your palm when in your standard riding position. This is the most critical step; if the wing is angled too far up or down, it will not support your wrist correctly.
- Tightening: Tighten the clamp bolt until firm. Do not overtighten, as this may damage the clamp.
- Care: Keep the grips clean by wiping them with a damp cloth and mild soap. Avoid using harsh chemical cleaners that could degrade the organic cork composite. Because cork is a natural material, it may darken slightly over time as it absorbs natural oils from your hands, which is a normal characteristic of the material.
