race frames with lower bottom bracket
I know that a higher BB is the norm for cross bikes. But there are often times in a race, especially on dicey off camber turns or sloppy uphill remounts that I wish I had the reach for a quick foot plant to stabalize myself. Yeah, I know I should just work on my technique and bike handling, but coupled with my short legs and long torso (East Asian genes), the height becomes a little more pronounced when riding a frame fitted for top-tube length.

I know the Van Dessel bikes have a BB drop of 7cm similar to road geometry. Are there any other brands following this trend?
Some brands list BB height instead of BB drop. I'm not sure how to translate the two to make them comparable to each other. BBH seems to be variable depending on tire selection and/or there's not enough additional info to even bother with my rusty trigonometry skills.

I know that Specialized and Trek cyclocross bikes have road bike like bottom bracket drops.
I believe that there are several others these days but I don't have experience with them. You can check out the threads about bottom bracket height in the cyclocross forum on roadbikereview.

some 'crossers have compiled a lot of data on this topic
