thatguybenThese are great bearings, the cost differential of Grade 25 balls compared to Grade 300 is so small that there is no reason you should not be putting the rounder balls in your bike. These will go into all the bottom bracket and rear wheel hub services I do.
The only problem I had with these items is the delivery time. Normally Tree Fort takes two days from order to ship, this time it took six days, frustrating me during a week when I had time to work on the bike but was lacking key supplies.
