Stripped right back now so had a good look under a 10x lens, looks like there are 2 gouges and it’s hard to tell but both look to have a hairline crack in them, but it might just be the shadow of the gouge.
I’m sure i’d have noticed this when fitting the crown race if they were there last week. No grit or anything in the race or round the bottom of steerer which might have caused the groove. Bike was reassembled so I could trim cables and set everything up, but not ridden as the forks needed servicing first.
Anybody seen similar before? Could these have been caused by over tightening the star nut and putting too much preload on the bearings? I’m pretty sure it wasn’t overtightened as I only nipped it up until all play was out of the headset, but i’m struggling to see what’s caused it.
I did fit the wrong crown race first (too many spare headsets floating around…) which was very tight to get on, but did go on. Took it off when I realised and the correct crown race went on, this time fingers were enough to get it home. Could the first race being too tight have caused it? My only thought could be it was an undersized crown race, but anything too small would surely not have gone on.
Any thoughts from the hive mind?
