thanks a lot Grizzbob. that cleared a lot of things up for me. i can't decide whether to go with the 48 pitch or 64 pitch. i will probably go with the 64 pitch simply because there is less resistance in the drivetrain with it and i also have more variety of gear changes i can make.
haha, one last question.
how do i determine whether or not my belts are tight enough? once i have broken them in, i know i will need to retighten them (going on what everybody has said). should they be tight enough so that they still give a little when i press down in them, but yet loose enough so that they do not bind up the drivetrain? i have little experience with belt driven cars, so any help will be appreciated by this EP TC noob.
