🔧 Oumers Professional Bike Crank Extractor and Bottom Bracket Remover Tool Kit with 16mm Spanner/Wrench - Essential Bicycle Repair Tool for Optimal Maintenance Review

It worked on a Shimano crank, it wasn't fun at all. The damn thing was very tight! I figured I could use the orange socket wrench, but it's not that useful. I used a 9/16 socket wrench to knock the crank out. I mean it makes sense to see how small and flimsy that wrench they gave me is. Luckily the main tool I needed was the crank part. I laid the bike frame on my slippers and then smashed it with a 9/16 wrench, which thankfully didn't damage the socket tool. Both Shimano cranks took a few hits

Worked great. There are several tricks to do this. First, you need a high-pressure lubricant. If you ride your own bike, you should already have one. Brush over the threads, including the threads of the part that attaches to the connecting rod. This keeps the aluminum from sticking to the steel.

The two parts fit together quite nicely if you just screw them together as "dry"…
