I originally purchased the Motion Pro version of this blind bearing removal kit but it did not allow for size adjustments for different bearing diameters. Basically, Motion Pro's instructions say that 20mm can ONLY be used for 20mm ID etc. So it didn't work for my 22mm front wheel bearing and Motion Pro doesn't sell a 22mm blind bearing removal tool. However, ALPHAMOTO allows a range of sizes for each tool. That way I could use a 20-24mm tool to push out the 22mm bearings in my wheel. It took me less than 10 minutes to remove both bearings without incident. Of course, the wheel and bearings weren't rusty or corroded. The build quality also seemed on par with the Motion Pro set.
