 "text": "My Sensa Cintura came with the budget CDN line of the Gates Carbon Drive, and after 1800KM the original rear sprocket was showing serious wear. I was disappointed by that quality and by Sensa's choice for the CDN line.\nThe fix was simple: I replaced only the rear sprocket with the better CDX model. After 6000KM of commuting, including a snowy winter that would have easily damaged a traditional chain and derailleur group set, the CDX sprocket was fine.\nThe rest of the CDN system held up well. The belt and the front sprocket are very durable; the rear sprocket is the weakest part. Combined with a Shimano Alfine gear hub the drive was ready for many more kilometres.",
