Review on microSHIFT 3X7 Speed Black Twist Grip Shift Gear Shifters - Shimano Bicycle Compatible by Ryan Lindstrom

These derailleurs look exactly like the ones on my son's bike and replacing them was a fairly easy job. Unfortunately the quality wasn't excellent. The 3rd gear shifter works well but there are problems with the 7th gear. It gets stuck between a few gears and has to be twisted very hard to change it, and sometimes it doesn't click at all between some gears. I noticed these issues before installing it on my son's bike, but I was hoping that once they started appearing, it would magically fix itself. it's not like this. I would probably choose a different brand if I did it again. It's hard to tell if I just got one bad one or if they're all equally bad quality.
