The bike has got two three- speed SA shifters. It is a five speed bike (old five speed hub with two wires). I would say pre 2009. There should be a number on the hub indicating what year.

My bike had the same hub (and therefor did not have the thingy to mount the der on the right chainstay). I therefor decided to go for a modern 5 speed hub with one shifter and I am wery happy with the solution. The hub I bought is no longer in production but may be found lying around in several shops.
