Cant think of any cons. The drag is imperceptable - the equivalent of a climb of five or six feet over a mile.
The benefits - 'free energy'. I fitted a hub dynamo to a new bike and was very impressed with the light generated by the LED lamp that I purchased to go with the dynamo.

Dynohub. I also have a couple of bottom bracket dynamos fitted to my other bikes. They are no longer made though.
I think that there might be difficulties in making the bracket/mount robust enough to cope with the pounding that the torch will recieve when cantilevered off a fork mounting point. Halogen and LED lamps have low mass and do not place much of a strain on the mounting points.

When my new bike arrives this month it will be fitted with a Schmidt SON dynamo hub, Lumotec IQ Cyo LED front light (brake bolt mounted) and on the rear a Seculite plus with standlight (it'll have mudguards).
..and if that ain't the business, I don't know is.

Yep. I've got one fitted to my bike it beats anything that I've had on the halogen bulb front.

You can run a front light with a bar bag.
Take a look for a Minoura Space Grip bar extension.

I mount mine on the stem, and have a bell, light and cycle computer fitted to it.
That said, I have a SON dynohub on my tourer and a Shimano dynohub on my commuter. Both are excellent.

I have Shimano dynohub and Cyo combination. The light is phenomenal - I honestly didn't think a dyno light could be so bright. And it's all good, broad spread lighting. There have even been times were I thought there was a car coming up behind me! And, at first, I was flashed by on-coming traffic because the light was so bright.
Must admit thought, and this could be a false perception, I think there is more drag than on my previous light (a Lumotech Oval Plus).
My reason for switching to dynamo lights (around 3 years ago) was that I wanted 'fit and forget' and not to worry about batteries etc.

There will be more drag.yello said:
A Lumotec Oval will use 3W, the Cyo will use 6W, and with a hub efficiency of 60% that means you've got to do 10W more work to do the same speed (or do 29.4 kph instead of 30).
