I'm building up a slalom bike, and bottom bracket drop seems to be something to think about according the manufacturer (Planet X). Apparently, if I run a 5" fork, there will be no bb drop, which I'm assuming is the level of the bb in relation to the dropouts. If I run a 4" fork, there will be 1" of drop.
Are there benefits to either one aside from clearance? Does anyone have a travel preference for this type of riding?
