Ouch, I just got into my first bike entanglement.
Was cruising along 20mph (ish, it was right at the bottom of a quick down slope) through a tunnel underpass. I was behind and a bit to the right of the biker in front of me.
They start braking hard and veer right. I brake hard, shout, shout, veer right and slam in to the wall and go tumbling off my bike.
The other biker was thankfully okay.
Got a big burn on my bottom, and some cuts and swelling in a few fingers. The seat of my bike came off the rails, and no amount of pulling or bending can get it fitted back on. I tied it down to the rails and shakily made my way back home.
