For the past 3 years I've commuted on a road bike with a relatively aggressive geometry. There's nothing inherently wrong with this bike, it rides great, but my own naivety led me to believe that I wanted to commute on a drop bar road bike that originally came with 23mm tires.

Lately I've been thinking about an ultimate commuter for me. Honestly I don't even know where to start in looking for a bike with these characteristics.

Things I want.

• IGH: 8-12? speed
• Preferably drum brakes (disks acceptable.)
• Drop bars preferred
• Not "cruiser geometry", I go fast when I commute, I want the bikes geometry to reflect that. I have no problem with an aggressive bike (I'm young and flexible) but I'm open to less aggressive options as well.
• Ability to mount 28mm tires? (I've never had anything other that MTB and 25mm road bike tires. I think I'd want ~28mm?) However, 25s with full length, well fitting fenders would be fine if need-be. I currently have 25s on this bike with raceblade long fenders. They're... acceptable, but barely fit. It's mostly the bike frame's fault, as it was never built for fenders. I've also broken various bits 3 or 4 times over the past 3 years with these fenders so I'm about 50% on whether or not I like them.
• Obviously fenders, but I can put those on if need-be.
• Obviously rack mounts. I have panniers now, so I'd like to be able to mount my rack to the bike.
• Edit: A dynamo would be a cherry on top of the cake. Forgot about that.

Sure, I could build this myself, but it's always cheaper to buy a bike with the things you want than it is to upgrade a different bike. I've really never looked for IGHs or drum brakes before. I don't know the brands, what's good, what's bad, longevity, maintenance. I've looked at Sheldon's site on the issue, but that's it.

I'm in the US. I don't have any problem with buying bikes online (my commuter is a BD bike) but I'd like to be able to try it first for fit.
