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.

Bike standards:

  • Flat bars: Found on nearly all mountain bikes, many e-bikes, many commuter bikes
    • Grip diameter 22.2mm (7/8”)
    • Clamp diameter: 31.8mm (1 ¼”) - current "oversize" standard, 25.4mm (1”) – standard on pre-2000 bikes, 35mm - new style from roughly 2020 and on
  • Drop Bars: The classic road bike handlebar found on road, gravel and tri bikes
    • Grip diameter 23.8mm (15/16”)
    • Clamp diameter 31.8mm (1 ¼”) - current "oversize" standard, 25.4mm - current ISO standard, 26mm and 26.4mm – pre-2000 Italian standards
  • BMX/ kids bikes
    • All dimensions 22.2mm (7/8”)
  • Cruisers, other bikes: swept back bars
    • Varies greatly from 22.2 – 31.8mm

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.
