That’s Mister Chalet to you ....
I've never even heard of these 'combs' before. Time to google something.
Mine was showing signs of fatigue, like a crazed cracking staring to appear, but when I took it off it was soft and pliable and seemed to still be a good fit, the "cracking" lines were superficial only and didn't open up further when bending or manipulating it, so I put it back on. If I had changed it, it would have been for aesthetic reasons only.I'm trying to figure out if I need the big top dust seal! The one that fits over the top bearing. The All Balls kit says seals included, but do I need that big seal extra?
