Will it Fit?

There is a lot of variation on handlebar diameters, so this quick guide will help you understand which Mirrycle and Incredibell products will work on your bike.

To see which bell fits your bike, determine what type of bike you have and identify what part of the bars you wish to mount it, then check the table to see what Incredibell will work with your bike's bars.

First, a couple of definitions:

Grip area – The area of the bars you normally hold with your hands, where you rubber grips or handlebar tape are located
Clamp area – This is the reinforced or bulged area in the middle of bars where they are clamped to the stem.

Bells:

If you have a non-standard bar or riding configuration, the following bells work very well to accommodate non-typical situations:

Mirrors:

Mirrycle mirrors are wedged in the inside diameter of handlebars. Depending on the material used (Aluminum, steel, titanium, carbon, etc.), your handlebar's internal diameter can vary greatly.

Mirrycle mirrors are designed to fit handlebars with 13.75mm – 22.5mm (.54″ to .875″) inside diameters.
