Shimano/ISIS Bottom Bracket Tool

Needed to replace the bottom bracket on my '98 Giant Iguana. It's never been off before and this bike has seen some miles. Almost bought the $9 socket, but have learned my lesson about cheap tools, even if you only expect to use it once, and I'm glad I listened to that little voice. Two days of penetrating oil (which did nothing), a heat gun, a ball joint C-clamp, two and a half feet of leverage, the BBT-22 socket and no small amount of gorilla torque were required the break that GD bottom bracket loose. Seth Alvo would have been proud of my janky setup! This is were the Park Tool BBT-22 impressed me. I honestly expected the splines to fail before I broke the torque, I'm not lying, it was ridiculous. But when I got it apart, the tool showed virtually no indication at all of it's ordeal. Honestly impressed. See the pics, I really had to use a ginormous C-clamp to keep the socket engaged while I turned the earth on it's axis to break that thing free. I took a picture of the socket afterwards for proof of its durability.

It fits and it works as intended. Most certainly worth the price, given what it would take to do the job less this socket. I used it on a couple different models, Trek and NEXT, very different quality of bike, manufactured about a decade apart.

Well, I broke the first one. The Bottom Bracket was really tight and I did not bolt the tool to the BB Axle using the Crank retaining Holes. The tool slipped, broke out the plastic BB retainer on the non drive side, and the tool cracked. I managed to get that side out after bolting the tool to the crank Axel and using a 1" deepwell socket and a 1/2" drive ratchet. The tool disentegtated while trying to remove the Drive side BB retainer. So I ordered a new Tool. This time I bolted it down, used the 1" deepwell socket and added a 30" breaker bar. I also took the Bike out of the maintenance stand and set it on it's wheels. The retainer came loose,reluctantly, and the tool survived. Also make sure to clean the dirt out of the splines on the retainers. Also remember, as the bike is sitting on the ground the right side turns clockwise to remove it. On the left side of the bike turn it counter clockwise to remove it. Suggest that you watch a few videos if you are a rookie.

My bottom bracket was coming loose from too much time on black diamond singletrack. I wasn't sure if I needed to replace it, so I bought a Park Tool crank puller and this BB tool. After some YouTube instruction, it was a cinch to take out the BB, clean it, and reassemble. The tools were absolutely essential (no surprise, since they are specially made for a certain task), but worked so smoothly as to make the process enjoyable. I'm not new to bikes, but new to doing repairs normally left to a bike shop. Considering that half the time the LBS has a teenage kid working on repairs, I decided to try it myself. Good decision.To use this, you'll also need the crank puller first, to get to the cartridge. You'll then need a large adjustable wrench to grip the hex-shaped area of the BB tool. The BB tool fits well into the Shimano BB, needing only a few turns to remove it. After cleaning, the tool quickly put the BB back on, nice and tight. (I didn't need a new BB, just this tool to tighten it.)

Item was sent out quickly, the next day, but that's not what make me glad that I purchased this item. The other tools I purchased as a combo was not up to par and I couldn't get the bottom shaft out as it couldn't grip the gear. This tool was deep seated and able to turn the gear shaft with no problem. Definitely worth the extra coins to have the right tool for the job.

It's sturdy and does what you need it to.It's a bit pricier than the alternatives, but it's backed by an established company so I doubt you'll have any issues.I've pulled apart and put a few bottom brackets together already and haven't had a single issue with it yet so I'm happy with it.My only gripe with this item is its price, it is a lot of money for what is essentially a piece of metal, but here's to hoping it lasts!

I had a cheaper tool to remove my bottom bracket, which I do occasionally to clean and lubricate. I hate a creaky bb! But cheaper tools don’t fit as well, slip out and I had to use a 1 inch socket on my 3/4 inch breaker bar and torque wrench to engage with the cheap tool. Park Tool is one of the few to offer this in a 3/4 inch wrench size, so no more jury rigged accommodations. Plus this will last a lifetime, made of real tool steel and machined precisely. It’s true - the only wasted money is the money you spend on cheap tools. It honestly was much easier to remove and replace my bb using a quality Park tool. It’s a joy to use quality purpose built tools, and Park Tool is the best
