Anatomy of a clogged drain

Recent house guests may remember how slowly the bathroom sink drained. Well, I took apart the trap and I think I found the problem. I’ve decided to link to the picture as a courtesy for the weak stomached. It drains faster now, but still not as quickly as I’d like. I tried snaking the line, but the snake wouldn’t make the 90 degree turn down into the stack. I opened a plug below the drain and snaked up and down without any problems, so I’m guessing the drain speed is just a limitation of the system. Or maybe there’s something at the 90. At least it drains now.
