So important to have the right tools for the job
I have a bottom bracket where the ONLY way to tighten and untighten due to the width of the external BB being less than a millimeter is using two of these tools. One on each side and a friend to help turn while I hold the two tools on with a fair amount of pressure. The good news is that I don't have to take my bike to the shop for BB adjustments anymore. The bad news is that I had to purchase two of these tools. I had previously tried (unsuccessfully) to use this tool along with the flat handled counterpart tools. My bottom bracket is Wheels Manufacturing PF30-THD. These tools when paired up like I described above do a surprisingly good job given the extremely thin BB material to work with.

Works very nicely
The tool's splines properly and securely engage the notches in the threaded BSA BB. It allows removal and installation without marring the BB. Various threaded BSA BBs have different diameters and numbers of notches, so check to make sure you get the right tool for the job.

Great tool. Quality build
Excellent BB tools (as expected) from Park. I own tons of bike tools and I only purchase these or the offerings from Wheels MFG. I like that Park color codes their BB tools though.

Innenlagerschlüssel von Park Tool
In Kombination mit dem Park Tool Werkzeug: BBT-RS ist es der absolute Hammer. Man kann es aber auch mit einer Knarre oder ähnlichen benutzen. Wie immer bei Park Tool sind die Sachen sehr gut dafür aber auch sehr teuer. Wer mehr Interesse hat, kann sich die Park Tool Sachen bei YouTube anschauen. Ich kann es nur empfehlen, aber sehr preisintensiv.
