Nice
I’ve put in exactly 1 sealed BB. I was a bit disappointed as I bought the Park tool and the BB was a Shimano UN55. What the heck, the tool barely contacts the splines. Tapped a bit with a hammer and didn’t get too carried away.
I just figured my tool or the BB just didn’t match up well. I would think the beauty of the spline setup was the easy availability of lots of contact area even with some manufacturing slop built in. Oh well. I will remember that.
