R-500 8spd brifter won't span triple crank
Hi. New to the forum (forums) and I need your help.
New Shimano 8 spd brifters. Left side (front) does only 1 2/3 swipes of upshift, which only gets through two of the three chainrings. 2/3 into the second swipe it stops just before the second click. With a return back to vertical a third swipe goes less than a click before coming to a stop (with no actuation of the cable if it is connected). The brifter behaves this way whether or not there is any tension or even a deraileur cable attached.
Is this normal? Shouldn't the brifter make a full second swipe to get to the 1st or 3rd chainring?
(The XT deraileur shows full range of motion when I manually stress the cable by pulling sideways on the section along the down tube, so the brifter seems to be the cause.)
