Adjusting tension of 600 shifter
I don't know very much about the Shimano 600 tension shifter, with my setup I have no problem with the front derailleur shifting, however with the rear derailleur I am able to shift with no problem but when I release the shift lever the rear derailleur returns to the small rear sprocket. I believe it's a tension issue but I haven't been able to find any helps that would point me in the right direction. Thanks
