Very happy with the bearing, it fit my Campagnolo bottom bracket perfectly and it's better than the original because it is sealed on both sides. The original failed due to the lack of a seal on the inside edge. Thank you!
verry good
These bearings are excellent quality and fit was pefect in my Alchemy racing hub. Super upgrade to the stock bearings. Hub spins forever with these bearings installed.
