From Shldon's site-
"Traditional front derailers are "bottom pull", operated by a cable running up from the bottom bracket area to the derailer.
"Top pull" derailers are operated by a cable running down from above. This design is mainly used on mountain bikes, with the intent of avoiding running the cable under the bottom bracket, where it is exposed to spray kicked up by the front tire."
