Durace 7900 C50s.
Any little downhill and the bike picks up a ton of momentum. I am a pretty quick descender, but I found myself on the brakes a lot more today. You release the brake and the bike moves like a sprinter out of the gate. I think I could have easily hit speeds of 40 - 50 miles an hour if I had been game. Not on a mountain road with two way traffic.

Now if the road were closed and I could use both lanes...
