Bottom Bracket Tool Bottom

Far be it from my to figure out why BB manufacturers can't even pick a spline diameter and pattern for external cup BBs so you need multiple tools for what is essentially the same piece of hardware. But, suffice to say, this fits an Ultegra BBR60 perfectly. Considerably less expensive than the Shimano or Park equivalent and for a tool that you use maybe 3 times (see comment above regarding constant changes to BB specs) that fits the bill. The advantage of a tool with a square bit like this compared to a wrench-style is that you can attach to the torque wrench.

I test fit it on a SRAM DUB - too loose. Quality would ok and fine for an attentive user - (keep it pressed on). Hey manufactures, all you have to do is punch some numbers on your CNC computer and you would sell a ton of these on Amazon. Tighten your tolerances.

Fit perfect for my Shimano bottom bracket and functioned perfectly. Great value vs the “blue brand”. Build quality seems good for you’re home mechanic.
