Review: Good - Excelente producto
Review: Installed easily and working perfectly so far. - Had no issue installing these in the front hub of my bike. Redneck tip: Put the bag with both bearings in the freezer for 24 hours before installation. The cold will contract the bearing and they drop in to about 75% depth without tools. You can then use a 1-1/16 (or similar) socket and rubber mallet to finish seating them. Just make sure they go in EVENLY and that whatever you are driving them in with contacts the OUTER race of the bearing.
