Please, in crowded areas or places with many bicycles,
it would be nice if you could split the group a bit or apply some brakes.
Just not knowing how many people are behind and passing through as a group while shouting,
later when you see it, more than 10 people doing that in a single line
personally, I wonder what the difference is between that and a no-brake fixie.
I understand the intention to go outside Seoul via the Han River, but within the Han River area,
let's be careful with each other. If someone gets hurt doing that, it's a loss for both of us.
