Bicycle 22.2mm Handlebar Extension for Small Accessories

thingiverse

Here's another simple solution for a handlebar extension for most of the common bicycle handlebar diameters. This one is useful for small clamp diameter accessories like ring bells, small bike computers or light switches etc. For example old school bicycle ring bells are almost exclusively made for 22.2mm handlebar diameter, so here's how you can mount such bell for example to a modern drop handlebar 31.8mm mid section, which was the use I originally modeled this for. Of course you can use it as you wish to mount anything you prefer if it suits your needs, it's all up to your preference and needs. Included are variants for five different handlebar clamping diameters. Available are 31.8, 26.0, 25.4, 24.0 and 22.2. There is some tolerance on each of them to ensure proper fit on most bars, measure yours to print the right one. In addition you need 2x M4x16mm bolts and 2x M4 nuts, whether plain or nyloc is the same, but using some thread locker is advisable if you use plain M4 nuts, but that's not an absolute necessity after all. Please share your makes if you choose to print these, thanks! Check out the 31.8mm version of the same design concept here: https://www.thingiverse.com/thing:5179460
