The Right Tool for Removing/Installing the Praxis T-47 Bottom Bracket
This is the right tool for removing and installing the Praxis T-47 bottom bracket. Pricier than others, but fine quality. It fits snugly over the bottom bracket providing a sense of confidence.

A must for any bike shop or home bike mechanic! The color is gorgeous and the quality of the this product blew me away. It fits perfectly on the bottom bracket of my bike. The durability looks like it will last for many years to come.

Top quality BB socket for your Thread Fit 30
This is what's needed to install a Chris King Thread Fit 30. The CK tool was on back order and this was readily available. Thank you Park Tool. It's top quality and it's what was required to finish tightening the BB to 40nm for my gravel bike build. TIP: Use a zip lock baggy or similar thin plastic to cover your BB before pushing on this tool. It will lessen the chance of slippage and also prevent your nice new BB from getting scratched up.I do wish Park would make tools available in 1/4 drive instead of 3/8 drive since most all torque specs. in the bike world are in Newton Meters NOT FOOT pounds
