Thanks CP, i looked over the dérailleur just to be sure and all that stuff it fine. The problem is definitely in the shifter itself. Even though the shifters look practically new they are from the late 1990s. The issue is not terrible(yet anyways) and the bike is ridable, but i think i’ll keep an eye open for a good deal on a new shifter. The annoying thing is trying to find an 8-speed shamano shifter pod that is separate from the break lever.
