Different look, added washers
Overall, the idler works very well and fit into the mount hole perfectly. There are a couple things, however. The chain retention arms do not look like the picture. They are more like pictures of the other idlers, with a split in the middle to tighten around the mounting bolt. Also, the arm for the return idler would rub on the drive idler when both were in the most outboard position, and the return idler arm looked too short, so that the chain could potentially jump, when the idlers were both in the most inboard position. So, I added 2 2mm washers, 1 between the idlers to prevent the rubbing, and 1 inboard of the drive idler to limit the lateral range of motion.
