So I just order some tires and tubes and now need to replace chain and sprockets on my 79 cm400t. I've already ordered a jt front sprocket, 17 tooth and plan to order a jt 35 tooth for the rear. I think I remember that the standard chain is a 530, 102 links. Is that going to fit with the additional tooth on the front or should I go up in links and cut to fit? Doesn't seem one tooth would make much diffference, but I'd hate to get a chain one link too short.
