Quick Summary
The Hafny HF-MR090 is a bar end bike mirror with a 68 mm silver glass mirror. It is described as HD, uses a glass mirror, and has a 180° adjustable lens. The fitting stated is for handlebars with a 14.8 to 23 mm inside diameter, using open ended grips or a hole cut into the grip.
This mirror is listed as suitable for either left or right side use, and for mounting on the top of the handlebar or below it. The exact handlebar setup matters, especially because it does not work for Trek Isozone grips.

What to Compare Before Buying
- Handlebar opening: Check that your bar has the stated 14.8 to 23 mm inside diameter and an open end or a cut opening.
- Bike fit: Confirm your handlebar grip type, because this mirror does not work with Trek Isozone grips.
- Mounting side: Decide whether you want the mirror on the left or right, then match the installation position to your bike setup.
- Mirror size: The 68 mm mirror size affects the viewing area, so make sure that is the format you want.
- Adjustment: The 180° lens movement is useful if you want to set the angle precisely after installation.
Before You Decide
Check the exact model reference, the 68 mm mirror size and the handlebar inside diameter before choosing an offer. The bar end fit is the main decision point here, especially if your grips are not open ended. If your bike uses Trek Isozone grips, this mirror is not a match.
Setting the Mirror Position
While stationary, check the view from your normal riding position and adjust the lens so you can see behind without an excessive change in posture. Recheck the view if you alter the mirror’s position.
