BigWheeze, if you recall my sordid tale of woe with BikeBerry, I actually spoke to three different people about whether or not the kit included a 4G drive. They all said Yes it did. And of course, it didn't. I came to the conclusion, and said it out loud to their people, that they obviously had no idea what they were selling.
Bicycle-Engines.com came to my rescue with a true 4G, straight shaft kit I am very happy with.
Yup, I ordered the same one yesterday. When I asked bikeberry if they would simply send me the t-belt box, they said, "unfortunately we don't actually have any of those..." which says to me that they're deliberately misrepresenting the product, hoping we won't know the difference.
