Our thought is that we are putting too much torque on the chain when reversing directions. Either then or when hitting the bridge were when it usually broke. We have good alignment, and we try to have good tension but when looking at it today it looks like the toughbox mini's keep bending then we put a drive load on them, which looks to be changing the tension. Currently we are using 16 tooth sprockets on both ends, but might increase that next year. We are also thinking about using direct drive, because it was only ever the chain from the transmission to the center that ever broke.
