What are 510s?

The one time I rode my mountain bike with flat pedals, I wore my usual Shimano mountain bike shoes since the cleats are recessed.

So, catching up for July, I led a 49-mile ride on Sunday for the club. I used a route that someone else had devised and that I heard was popular, and reversed it for the sake of variety. It was okay, parts were very nice, but some of it used roads that are not my favorite for cycling due to the amount of traffic. We had perfect weather and a big turnout as a result, and everyone seemed to enjoy the ride. A couple of people slowed down quite a bit for the last 10 miles or so and since I was the sweep, I had to slow down too. This was only a problem because I was wearing shorts that apparently have been worn too many times, and they were causing some chafing. So I really was happy when we reached the end.

The new saddle was bothering me pretty much for the entire ride. The wide part of it has a domed shape, and I think this is what is causing the feeling of the nose being tilted up. I'm going to try lowering it a bit to see if that helps.
