If you need to replace Trek BB90 bottom bracket bearings, and want to make sure you don't ruin your frame or new bearings, this tool does the job perfectly. Wish I had purchased this years ago.
I used to tap in bearings using a block of wood and a hammer. This simple tool does the job better and easier without risking damage to the frame.
During the pandemic I've done a good bit of home mechanic work for friends. This was my first stab at PF BB. Tool worked flawlessly and appears to be constructed sturdily. I can see where the pro tool may have broader applications and quicker execution but neither were needed in my application
perfect out come replacing a BB30 bearing.
The easiest way to press cups and bearings. Quality tool that will last.
If you got the old one out properly, using this tool to install the new one is nearly effortless. Great tool, simple.
