I had a different question in mind, but I realized that I know little about shifters, other than I like mine, and not my husbands.
So, what type of shifters are out there, how do they work, and why is one kind chosen over another?
I have soft barrelly shifters that are like an extension of the handlebar grip- very comfy to rest your hand on. All I have to do is give it a twist one way or another and I go to the next gear. Walmart calls them grip shifters.
I like them because they are comfy and easy to use.
My husband uses what he calls index shifters, which don't go around the bar, but mount on top of it. There is a little tab that he rotates forward or back to shift. I hate them because the tab goes over my handlebar grip and my hand ends up resting against it uncomfortably. I also have to take my hand off the bar to move the little tabby.
What kind do you have?
