What is the exact difference between the Shimano 7710 and 7700. From what I have read both can be NJS stamped. The 7700 is supposedly lighter due using needle bearings which needs more maintenance if used regularly. The 7710 is all sealed cartridge and is better for "riding in the rain" keirin races apparently. Anyone have any opinions? Im thinking to just get the one that comes along for sale first
