🔧 Park Tool BBT-30.4 Press Fit Bottom Bracket Bearing Tool Set - Versatile Compatibility with BB30, PF30, and More! Review

Fits me perfectly. Instead of paying $79 for an extra tool to press in new bearings, I used a 5/8 bolt. This tool includes cups for truing and installing new bearings. An additional tool is to simply squeeze them together.

For the weekend warrior when your bike needs a bottom bracket replacement this is a must have tool. You don't have to miss a ride if your local bike shop is closed. You can do your job. It's very easy to build a BB30 with Ultegra cranks. You will need a press tool, buy or make your own. Profitable investment.

Works mostly as advertised. The grip tip is a bit gnawed from the tap so I wish they had used a higher quality metal that doesn't wear and warp as easily as it looks. I only had to take out a few BB30 bearings although for the money I paid they would hold up better.

I used it on a Cannondale CAAD 10 BB30 bottom bracket. After several consecutive hammer blows it moved from where I had positioned it, but this is a really useful product. I don't know why they include two pieces to install the bottom bracket when that requires a completely different tool. I'd have to buy something similar again, I'd look for one of the tools that pull the bearing out with a screw mechanism rather than knocking it out.

Replaced standard BB bearing set with ceramic. Not only did this tool make it very easy to knock out the old bearings, but the BB30 fittings inserted my new bearings with ease. I used a bolt with washers and a nut to press the new bearings into the frame. Went like clockwork. Took me about an hour from start to finish. Bottom line: If you're a home mechanic and feel like you have the skills to take the drivetrain apart and swap out the bottom bracket bearings, this tool will get the job done.

The owner of a bike with a PF30 bottom bracket has the choice of buying this tool or another bike. I bought it with the Park HHP-3 Bearing Press Tool. Now that I'm tired of the squeaking, I can remove the bearings, lubricate the bottom bracket shell, reassemble it and enjoy three months of smooth riding. The included bearing mandrels are the perfect size for pressing in bearings, so that's a bonus value! If you have a noisy PF30 or BB30, get this tool, buy a new bike, or live with the creaking.

It's easy to use but can be awful for taking a hammer on your bike (via the tool). If you're stuck with an extremely squeaky BB30 (the worst invention ever made on a bike), you need this tool to remove the bearings so you can try to stop the nasty squeak. Unfortunately, you need to buy another tool to install BB. The BBT-30.4 is expensive because it's basically a fancy stick. Maybe manufacturers will switch to a different BB standard if enough people buy it. Please do your duty and buy it.

This allows you to REMOVE the BB30 bearings but not install them yourself. In the picture you can see the main removal tool, as well as two installation "cups". These mounting cups are used during the installation process, but this tool alone cannot install bearings. The description may be a bit unclear, but I'm familiar with press-fit type bearings, so I knew right away that I would need an additional tool to install them. The removal tool works fine, just make sure it's actually installed in…
