Park Tool HHP-2 Bearing Cup Press
Park Tool has the answer to your headset and cartridge cup pressing needs. The HHP-2 accurately aligns and presses 1", 1-1/8", 1-1/4", and 1.5" headset cups. In addition, it presses cartridge bearings and cups into one-piece bottom bracket shells and holds fixed cup wrenches firmly in place when removing or installing adjustable-type bottom brackets.
I have to say that Eric P's review was a little unfair. If pressing a very specific bottom bracket bearing was the goal, he should have double checked compatibility first, or perhaps purchased a bearing press instead of a bearing CUP press. I think this tool works remarkably well. The quick adjust bracket in the bottom right of the photo is a particularly nice addition, as it makes this tool very easy to set up without a lot of spinning of the screwy bits.
Super expensive, and doesn't come with everything you need to press bottom bracket bearings. Unfortunately, what this products description doesn't make clear is that the #669 bushings used to install a press fit bottom bracket are not included with HHP-2. For the price of this tool, it seems like they could easily be included. Yes, this is a good press fit tool, but it should only be used with bottom brackets with the #669 bushings which are not included with the tool. I've purchased a lot of Park Tool tools in the past, and this is the first time I've felt that an expensive tool of theirs has really come up short, as it is really only a Headset Bearing Cup Press without the purchase of the additional #669 bushings, which are a significant additional cost for the average home bike mechanic. (The #669 bushings are included as part of BBT-90.3, which also includes the tool to remove an existing bottom bracket.) If you're looking at buying this tool to install press fit headsets and bottom brackets, make sure to factor in the cost of the BBT-90.3, at which point you're looking at roughly $200 all in. Ouch.
Just purchased this thru PP and used it on my recent DH bike build. Tried using a home built unit but was having issues aligning the headset into the steering tube. The local bike shop was busy and eventhough they were willing to do it for a few bucks, the wait time was unacceptable. So, after several attempts with my home built unit, I gave up and ordered this tool. When it arrived, I was surprised to see it. This is one hefty delicated tool. Within 5 minutes my new headset was on the bike. I am very impressed with this tool. With the two handles and the pre-cut grooves on the shaft, setup was a cinch and pressing the bearing cup was effortless. The two die presses automatically sets to the size of the headset and aligns the press. It's become a valuable tool in my home shop and now that I have it, I will be replacing two other worn out headsets and converting one from a straight to a tapered tube fork. Sometimes PP will have a sale or a discount so unless your in a hurry, wait and take the hard to pass up deal.
