What to Compare Before Buying
- Frame mounting points: Check that your bike frame has threaded pre-drilled holes and that the spacing matches the stated 60 mm requirement.
- Bottle size: Compare your bottle diameter with the stated 7 to 7.4 cm range.
- Pack quantity: This is a 2-pack, so confirm that you want two holders rather than one.
- Included hardware: The package includes screws and a 3 mm Allen wrench, so check whether that matches your installation plan.
What Else You May Need
You will need a compatible bike frame with the right mounting holes, plus the bottle you plan to carry. If your frame does not have threaded holes, this holder will not be the right choice.
Before You Decide
Confirm the frame mounting holes, 60 mm spacing, and bottle size before choosing an offer. Also check whether you want the 2-pack configuration and whether the included screws and 3 mm Allen wrench cover your installation needs.
