Here's a pic of my Surly Disc Trucker.

Except for the trunk bag and water bottle this is the way I got the bike. Notice the friction shifter on the down tube. Right now the friction shifter it the only thing I don't like about the bike. Well, the other thing is the Presta air valve. I've never had or used them and can't figure out how to get the air in. I'll end up going to you-tube for a Presta video.
