What do you guys think?
It's been done, some swear by it.
Edit: A quick google session led me to this: http://g-tedproductions.blogspot.com...bike-tips.html
Drops won't accept MTB levers, the diameter of the grip is larger.
Planet X, On One, (I'm missing one....) all make a MTB drop bar. Also look into perhaps mustache or 'dove' bars. Any of the above will require a shorter stem. There is a good reason this is not widely practiced.... John Tomac did it for one year about 20 years ago, and went right back the next season.
There is a member on here that only uses drop bars on his mtn bikes
Salsa used to at least, I didn't find it last time I was on their site.
