Title: Broke after 3 years
Review: These shifters are great when they work, but my rear shifter stopped indexing after only 3 years of fairly light use. They still shift in friction mode, but for the price they should last a lot longer than they did. I have thumb shifters from a 1987 mountain bike that still work great so I don't understand why these are not just as durable. I will try Microshift's bar end shifters next time.
