As the build of my new Calfee approaches I need to decide if should spend the extra money for the belt drive ($525 vs $50). As I understand it the advantages are lighter weight, less noise, no grease or lubing, longer life, less stretching and so fewer adjustments of the eccentric. If the price was half of what it is or if I had idle money I would not even think about it. But having spent close to $8K already I am getting wallet fatigue. I am thinking maybe I can just go with chains for now and maybe in a year I will feel better about spending the money, or the price will have gone down or Gates will stop making it. Any feedback would be appreciated.
