I went for a ride today, and met some dirt jumps and went off some. On one, I did a bad x-up and fell on my aisde, the handle bars turned still, locking my leg. I was fine, but the rear derailler shifter had issues. I can use the trigger that causes the gears to become smaller, downshifting, but the one that rasies the chain gets stuck and after shifting up 3, I can't let it shift further. Help. Please.
PS. Theres no dirt caught in between the triggers.
