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 front 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.

cyclingmikeI'm not building a particle collider here... just repacking a bicycle hub. The price difference is minimal between a Grade 25 and a Grade 300 or 1000 and the tighter tolerances and roundness of the bearings makes a notable difference in any rolling application (like hubs).
My wheels were noisy, first I tried repacking the bearings and realized that did not fix the problem, so I replaced the ball bearings and now it spins smooth as silk and quiet as a church mouse.
