stuck crank arm, made the job of removing it easier and hassle free, small enough to fit in my tool box without taking much space. Definitely recommendVery easy to use. Took crank pedal off easilyI am new to bike maintenance, and I am trying to slowly build myself a set of tools that I will be able to use for the long time. I do not want to have multiple duplicate tools.Sadly, I cannot recommend this tool as your only crank puller tool. The handle is too short to have enough leverage, so if you ever happen to work on a bike with a difficult crankset to remove, you won't be able to have enough leverage with this tool. What is sad is that they could have added a 1/2" drive hole, or even a bolt head, on the back so you could use wrench to get more leverage if necessary.But you are stuck with the think handle which will hurt your hands and provide very limited leverage.So I ended up having to buy another crank extractor tool, one which will allow me to use a breaker bar. It's unfortunate. If they just added a bolt head to the back of the tool, I could have saved the day, but no, have to get another tool.So, not recommended, unless you want to have multiple crank pullers and want to reserve this one for the easy situations.does exactly what I need it to do.Useful and works as intended but be very careful not to let the piece on the end come off in your cranks. It tends to come off and if you don’t notice it you’ll ruin the next crank you fry to pull off. I learned this the hard way with a very expensive set of vintage Campagnolo cranks.I needed this to remove and replace the flywheels on my rower and the puller worked exactly as expected. Now a mainstay in my toolboxI had become progressively frustrated with my inability to remove/separate the crank arm from the fly-wheel of my recumbent exercise bike. This exercise in futility started shortly after the pedal loosened up and stripped out the threads inside the crank arm! What I thought would be easy, slowly became next to impossible. As a man, I hate to admit defeat, but I knew I needed more than a hammer and screw driver, but I was at a loss of knowing exactly what I needed to finish the job, or where to find it!So, after trying everything I knew, to separate the crank arm from the fly-wheel, grew increasingly next to impossible, I broke down and purchased a new exercise bike. Even so, that spirit within me, that doesn't give up, kept searching the web for help in removing this crank arm! Then, lo, and behold, I came across a short film on you.tube [less than two-minutes], and I found the Crank Pulling tool, and it looked, per the film, to be simple. I said to myself, "If it's that simple, I could even do it!"So, a few hours after I bought the new exercise recumbent bike [on line], I ordered the part Pulling Tool. It arrived two-days later, and I found the tool to be as easy to use as the DIY film showed it to be. And after successfully removing the crank arm, I got on the phone and canceled the order for a new exercise bike. From there, I pulled up the Schwinn parts site, and I bought two new crank arms and pedals, and more importantly, including the cost for the pulling tool; I saved nearly $300.00, plus I will get to keep the bike I loved and used for more than ten years!Now, what makes this even more interesting is that I am not mechanically inclined, so for me to say that this tool is easy to use, is not a lie! I love cyber space, because there is so much information available, and most of it is life, and cost, saving!If you are not sure on how to remove the crank arm of your bike or exercise bike, before you scrap the old bike and order a new one, just consider p this Crank Puller Tool. If I can do it, 99% of you can do it too!Decided to spend my off-season revamping my bike. Chose to save money and buy a cheap kit with several tools, including a crank puller. Big mistake! It was junk. When I tried to use it, it completely stripped the threads out of my non-drive side crank arm. After spending days trying to get it off, I finally resorted to a hacksaw. Thankfully, I was already replacing the crankset and bottom bracket, but it would have been nice to have my old parts as spares. Anyway, I ordered this item and abandoned the project until it came in, which only took a day. First time I used it, it was so easy, I first thought I broke something else. But no, it just worked. Simply. Easily. I see others complaining that it’s too short to get good leverage. I did not have that problem, and my upper body strength is crap from two surgically repaired arms from the bike wreck that ended my 2019 season (broken left arm, torn rotator cuff and biceps in right arm). My point is, save yourself all the hassle I dealt with and just buy this. It’s well made and won’t tear up your bike. Park Tools has a new customer for life.I'm quite surprised by the number of 5 star reviews for this product. I own a lot of bike tools, many of them by Park. This is my least favourite, and one I intend to replace.First, let's start with the obvious. This tool doesn't come with an integrated hex wrench like many of the other crank pullers. As such, you'll need two tools to finish the job, which is frankly annoying.Secondly, the fact that this is described as having "a long, comfortable handle" is absolutely laughable. This comes with an EXTREMELY short handle that's quite thin. It's about one third the length of my Park Tool pedal wrench, meaning you don't get much mechanical leverage at all. There's a reason for this; they want you to be able to use the wrench without removing the pedals from the crank i.e. the wrench is short enough that it won't hit the pedals. If you have a difficult crank, this tool simply doesn't provide enough leverage. I found myself having to bash the tool with a hammer to get the cranks off.Third, this doesn't support Octalink and ISIS drive bottom brackets; you need another tool for that. Some other manufacturers managed to make a "universal" crank puller but Park would rather you buy more tools.Fourth and finally, this tool comes with the Park "premium" i.e. it's overpriced. Granted it's not going to break the bank, but it's more expensive than alternatives. Normally I'm happy to pay that premium for a quality product, but this just isn't it.Good tool all in all, but not 5 stars round tool.In my opinion, handle should be longer to increase leverage, even if pedals have to be removed, which is not such a great disturbance considering the number of times a crankset needs to be pressed off.Due to the shorter handle, I had to use a wrench in conjunction with the puller tool to increase leverage during removal of a tightly fitted crankset.Admittedly, tool did the job and material used seems to be of top quality, however, tool handle blue sleeve took some damage due to extra wrench pinching on its edge.IMHO Park Tool should offer an alternative tool with a longer handle.Used to remove the crankset from a 2011 Giant Defy 4 due to the drive train being worn I needed to upgrade the chainrings which due to the age were becoming quite difficult to source and when found were more expensive than buying a newer crankset. The process was simple and the tool was very easy to use too. The handle is flat and relatively comfortable and there was enough of a lever to allow for removal. I like to do things myself so for me, the item cost was worth it as I enjoy the process however if you are just doing this once and changing the BB out to update your bike to newer technology the likelihood is that you will only use this once so may seem like a bit of an expense, but if you are a mechanic or an enthusiast then this is a useful item of high quality to have in your tool kit.I am a big Park Tool fan and I do like this tool however.... In the REAL WORLD (not YouTube video step by step on brand new removals and refit) you are removing quite corroded stubborn crank arms and this tool is far too short for this application as it is too hard to get leverage. The only way forward is to either insert a hollow bar over the tool or use a soft blow hammer. Other brands in the market look similar to this. As much as I’d like to give it 5 stars I can’t, that said it doesn’t mean I wouldn’t recommend this tool, they may all be like this.Bought this for my Trek Marlin 8 to swap the chainring over from the existing 30T to a 32T (SRAM SX Eagle). Made the job slick and trouble free. Previously bought one of the cheaper bog standard crank pullers which was useless, not saying one of those many cheapo ones wouldn't have worked, but if you've spent a fair bit on your bike then don't faff about skimping on the tools you need and get this!
