Worked like a charm on my 2015 Trek Remedy 8 (PF41 / BB89.5 / GXP)
On my 2015 Trek Remedy 8, I'm swapping out the stock 2x drivetrain for 1x SRAM Eagle, and part of the process requires switching to a SRAM Dub bottom bracket. The world of bottom bracket terminology is a bit confusing, but I think the stock bottom bracket + shell I had on my Remedy was PF41 / BB89.5 / GXP. The shell is 89.5mm across and 41mm in diameter, and the bottom bracket that comes with the bike is 24mm on the drive side and 22mm on the non-drive side. I'm mentioning this in case anyone has a similar Trek bike and is as confused as I was before doing a bunch of research and finding this tool.I hesitated to buy this tool because it's essentially going to only be used once, but after a bunch of hassle of unsuccessfully trying to remove the existing bottom bracket without the tool, I finally caved and bought it. When the tool arrived, it took several whacks from a rubber mallet, but it worked like a charm to get the bottom bracket out, and I can see the value in having such a tool versus some other more makeshift methods, especially if you're going to use it more than once. But even just using it once, the amount of time I saved by just using the proper tool was probably worth the $45. At this point I'll probably just hang onto it and lend it out in my local mountain biking group or sell it on craigslist.In any case, from what I can tell, the BBT-90.3 is absolutely perfect for this kind of bottom bracket (PF41 / PF92 GXP) and worth the $45.

Pure joy to use
A tool that is worth every cent, and a tool with such a simple design puts a smile on my face.

Simple but effective tool
This tool is great for BB94 press fit in mountain bikes. I have successfully used it to drive out cups held in with grease and teflon paste, but not park retaining compound which is basically like glue. I don't use the drifts as I puchased a complete bearing press with higher quality machined drifts but they appear servicable. You can easily bend the arms slightly to gain additional pressure against the bb shell if your plastic cups have been tapped out before. Make sure to keep the driving end concentric with the shell you are driving the bb from to get a square impact on the cups instead of wedging them in sideways. That can be a bit fiddly since the shaft is by design smaller than most cranks.

It works, but not my type
The tool I got has missing parts. Other than that, this tool works well to extract BB bearing. But I still prefer using other kinds of extractors extract slowly instead of using a hammer.

Essential Bottom Bracket Bearing Tool
Essential tool to change out bottom bracket bearings. Read the specs to make sure this is the tool for your bottom bracket. The removal tool is easy to use. Just follow the straightforward instructions. You'll need a mallet of a block of wood the whack the tool to push the bearing- easy. Also it comes with 2 bearing press rings used to make sure you are pressing the bearings into the housing evenly and in proper alignment. You'll need a bearing press tool, or just as effectively you'll need a long 5/8" or 3/4" bolt, a few flat washers and a nut to use as a press. Again easy and the bolt, nut and washers should cost about $6 in a hardware or home improvement store. That's a lot less expensive that buying one of the various presses available. The best benefit of this tool is that you can change your bottom bracket bearings yourself and make sure that the bearings and seals are installed correctly.

Get the right tool.
Made quick work of popping out the press fit BB. Glad I spent the money on this. Now I have it for future uses!

Great for Trek BB90 and BB95
I bought this to replace the bearings in my Trek road and mountain bikes. With three carbon fiber bikes needing the same type of bearing, I figured it would be more cost effective to buy it outright rather than relying on the LBS.The tool taps the bearings out easily enough without damaging the frame and bearing sockets. The press plates work with the Park headset press, or one you can make out of a threaded rod. I cannot bring myself to buy the press, so using the threaded rod instead, I was able to quickly and easily press the bearings in, with perfect alignment. The plates align the bearings well, so there is no worry about doing it incorrectly, except for maybe using too much force. This has saved me $50 between two bearing replacements, so it has already paid for itself.
