please guide me how these gear shifters work?
That version had downtube shiftersEasy way to tell if the gears are indexed, does the right hand lever click as you move it up or down or can you rotate it all the way with no clicks?
I find it hard to believe that a new bike, no matter what brand or price would be sold with friction shifters unless you specified it as i had indexed down tube shifters 20 years ago.
The OPs picture shows down tube shifters so i believe i am correct in my assumptionsThat version had downtube shifters
