They don't have a brand name on them unfortunately. They just say 8 speed for the back and 3 for the front. The shifters have a trigger for your index finger and one for your thumb on each shifter. I bought the bike used at Sprockets in Denton so I'm not sure if the shifters are original or not. The bike brand is Specialized. Do you know of any sites that detail cleaning shifters? I try to do repairs and tuning myself.
