Fits New Shimano BB R9100
Nice quality of spanner. Found it cheapest and quickest delivery here on Amazon although I usually stick to bike shops for bike things. I was searching for an easy installation solution for the new style smaller bottom brackets from Shimano.The small side of this fits the new style (2018/19) Shimano groupset - R9100 - Bottom Bracket without having to use an adapter (FC24). The FC24 adapter does not all BB tools so watch out.Just for info - the large side is too big for the Ultegra 6800 and the 6800 BB adapter (FC25) is too big to press in to this spanner.I'm sure I might use the large end of the spanner one day with another brand of BB.

Easy to use, well made tool
A well made spanner for bottom brackets, fitted very well just need to be carful to keep it straight as it’s a thin spanner. Can be a bit hard on the hands but does the job well.

Top tool for a top class job
I had to purchase this tool to strip &. fit the FSA -BB386 B/B. I have 4 B/B extractor tools but none fitted this B/B . This is a must in the workshop .A top quality tool with two different size end's. I am very pleased with this and can confirm buying this from Amazon they are the cheapest on the net .Very happy with this tool .Crooky SOUTH WALES UK

Good quality tool
Bought this as I needed to replace a wheels manufacturing bbright. Very glad I opted for this rather than the cheaper options available as the bb was very tight and I thing anything less well made might have caused problems. 1 star off because as it’s double ended it’s quite painful to grip, needs a proper handle.

Does the job.
It’s ok. It does the job. Cheaper is available but I needed something over night so went for this. It’s basically stamped out of sheet metal which is fine, and probably hardened afterwards. But the stamping process does leave sharp burs on the edge which I wouldn’t expect from Park Tools.

Park Tool - Robuste Qualität
Schwere und präzise Ausführung!Etwas scharfkantig - die Verarbeitung müsste für den Preis besser sein!

Nice piece, but it didn't work for me.
I bought this to tighten the bottom bracket that came with my Shimano 105 R7000 setup. Although the dimensions seemed to be right, it didn't fit. It looks like a nice quality tool though. I don't fully understand the bottom bracket sizing and how to make them work.. Anyway I just ended up getting an ultegra BB from a friend, and borrowing the appropriate tool from him to tighten it. Note: this tool didn't fit the ultegra BB either. Maybe Park Tool can come up with a guide or chart on what tool to use with what BB? Maybe someone has already done that? I don't know....
