Park Tool BBT-9 External Cup BB and Hollowtech II Tool Tool

Ultra reliable Park Tools - does exactly what it should, would highly recommend

This is designed for installation or removal of 16 notch external bearings and is an excellent tool that is made to last. I used this to get a BB out of a friends frame that had seized in, no grease on the thread???, with the aid of a club hammer as a smaller one would not budge it; this left no real signs of damage to the tool which surprised me as I was welting it. The little plastic tool for the crank arm compression cap is removable but does spin freely on the arm so you can use it in its place, as it only needs between 4-6 in-lb of pressure to tighten it you don’t need to rip it up. The lever arm is 8½” (215mm) long so there is enough length to tighten things up, depending on rider weight or power production you may need to tighten it a bit more. The overall tool length is 11” (280mm) with the head width being 3” (77mm).

I don't have many Park Tool tools as they're outstanding quality, but normally significantly more expensive than alternatives. You no longer get the Shimano tool in the box when getting hollowtech bottom brackets, so I needed a tool. This fitted my exterior BB perfectly. Highly recommended.

Used to remove BB-R60 bottom bracket. Note that you need to use the adapter that is shipped with the bottom bracket. This is a very tight fit when inserted into this tool. The tool also includes the adapter to remove the crank end cap on the none-drive side. Knocked off a mark due to the cost of this tool which at £20 is pretty steep for what it is. Other than that it is great quality and it is always worth buying the best tools you can afford. They last forever if cared for.

This was up to the usual excellent Park Tool quality. It fitted my BB68 bottom bracket like a glove with plenty of leverage due to the long bar length. Made in the USA as well :o)

Got the job done. Installed the hollowtech ii with ease and got the preload cap of the crank on as needed. It's not the most ergonomic (quite thin with little padding) but is a great quality and will reach for it anytime the job calls for it.

Had to change my crank that was propper stuck. give this thing a good bashing with a hammer to try and get the crank off, even stood onit bouncing up and down it took me 2 days and a pulled neck(frm raggin onit) to do the job and this bad boy was standing stong looks brand new :-)

This tool is excellent and fits perfectly to a 44mm bottom bracket that has 16 notches. The tool took the bottom bracket of with ease and the other little thing on the other end unscrews the cap on the side that doesn't have the chain rings. Two tools in one, I can't fault it.
