They make covers to prevent chain slap damage to the frame...you can find them on amazon.....or use electrical tape works just as well or better...you may even be able to find red.
If you want the nut remover try calling customer service, I did. it was listed as out of stock but they had it, I didn't have any off set wrench so I bought the Juiced Tool for what a wrench would have cost me. My son has a Juiced also used it to change worn out rear tire,which is not that bad...
I have the SP12 very happy with it.....Bike Discount , Germany....high shipping cost but still the best price I could find..takes about a week to get it. About $80 total...23 of it shipping!
