I purchased this used on Mercari, but I'm selling it because I haven't used it much. The two bearings have been greased, so the rotation is smooth. The exterior condition is good, but there is a visible scratch on the handle cap, so I've marked it as "Slightly scratched or dirty." It's a small 55mm knob, so I believe it's for the [2500SHG], but it's a Yumeya [H-11] type, so please check the Shimano compatibility chart to confirm fit before purchasing.
