sora sis left wont downshift
just wondering if anyone has a trick to share....
I have brand new sora 2/3x9 sti shifters. went to mount them today, first time sti. did the right first, no troubles. checked the action on both after mounting, before cabling and all was well.
when I went to finally attach the front derailleur cable, the left shifter would not downshift.
these were working smoothly half an hour ago. never ridden, and haven't been out of my sight. I've tried putting pressue on the cable, so its not a slack downshift attempt, but no luck. the thumb lever seems to articulate just fine, but no downshift. I can't even get the cable out!
