I used the puller to remove the sprocket side crank on a Giant ATX bike. The bottom bracket insert had loosened up and needed retightening.
I was a Shop Foreman at a German auto dealership for 30 years. I have seen $300 German pullers destroyed. All pulling tools like this have to be greased prior to use.
As mentioned in other reviews this is not a professional quality tool. The bolt does not appear to be hardened. It became very difficult to turn with the supplied wrench and I STOPPED. I placed a ball bearing, approximately 11 mm in diameter, between the spindle and the puller bolt. This drastically reduced the force required to turn the bolt using the supplied wrench and the crank arm came off easily. There was no visible damage to the threads .
The bottom bracket tool worked perfectly. Make sure all grit and grime is removed from the flange splines.
I’m sure a bike shop would have charged more than twice what the tools cost, so it was worth it to me.
With the addition of the ball bearing I’m confident this puller will last for years.

Works as it should. No issues. Seems like good quality.

This worked perfectly. There are a few tricks to make it do so. First you need a high pressure grease. If you are working on your own bike you should have some already. Apply a dab to the threads including the threads of the part that attaches to the crank arm. This keeps the aluminum from sticking to the steel. Second, use a square nut or make a square steel slug to sit on top of the crank spindle. This will prevent the threads from being damaged. This is why the Park Tool tip breaks. The tip on this one is solid. Third is the real trick. Apply heat! The crank arm is aluminum and the crank spindle is steel. They will and do stick under pressure. Put tension on the tool, then heat with a heat gun. This will expand the aluminum. When you cannot touch the metal finish removing with the tool. No need to blister the paint, it doesn’t need that much heat. Final note: the part that threads into the crank arm only needs to be finger tight. If it doesn’t thread in, your crank arm threads are damaged an need to be cleaned and repaired.
BTW: The tool to remove the nut holding the bearings is a 1/2 inch drive socket ratchet. This was not a problem for me as I had rachet of this size. As with all ratchets, it is best practice to support the ratchet head while using. I had no damage occur during use. If you have a swivel handle ratchet, aligning your hand in the same plane as the BB nut will also reduce the twisting of the tool.

Needed to order this tool to get the pedal off my exercise bike to do some work to it. The tool worked great with a little elbow grease. It’s a little odd when it first shows up and you see the parts and you aren’t exactly sure how they work together. You can easily find videos online on how to use this tool and it’s really not all that complicated just a little confusing at first but once you see how it works it’s pretty obvious how to use it. It’s quite small so it should be pretty portable should you need to take it somewhere. It does do a good job at removing the part it’s designed to just expect to have to use quite a bit of force. The durability seems good enough but personally I would have liked it to be a little thicker for peace of mind.

Purchased this tool to replace a bent crankset on a new ebike. With the tool, was able to remove the bad crankset in less than 5 minutes and replace it with a brand new one.

IMO this is a very budget friendly, specific use tool that is great for the occasional use. The crank arm extractor works exactly as it should – don’t be afraid to put some force on it, but maybe use something to persuade it (your hand will thank you). I actually used a dead blow hammer from my auto tool box to strike the tool handle (the orange part) and it worked perfectly.
The bottom bracket remover (toothed socket head) is too crudely cast for fitting perfectly – the teeth were too big to fit inside both Shimano BB rings (the left side actually was ok, but the right side was not). I ended up popping for a Park BBT-22 at my local bike shop – and the difference between the castings is noticeable. The Park is much finer, and the teeth fit perfectly, allowing the socket head to seat much deeper in the ring itself. This is an important detail, as it takes a bit of leverage to loosen and tighten the BB rings.
Given the price, I still give it 4 stars – even without the BB extractor, it’s still a good value.

Received it today and promptly used it to remove two crank arms. Didn’t use the wrench, used an adjustable wrench instead. Was a little concerned it might pull out of the threads, but it was a needless worry. Very happy with it.
Used the bottom bracket socket yesterday on a very difficult to remove unit. Cleaned the engagement area very thoroughly on the bike. Sprayed it with a solvent to try and make it a little easier. Added a bolt through the socket to secure it from moving off the bracket. Was quite a chore to loosen. Eventually had an 8” pipe wrench and a 4’ cheater bar and the non drive side finally came loose. Drive side was much easier. Socket worked wonderfully. Hard to believe it didn’t fail under that much torque.
Turned out to be a great deal. Highly recommend the set, but I also suggest researching some videos on how to make the task easier.

Does the job. Value for money product.

It works –
Honestly I think a lot of the bad reviews are old probably from before the manufacturer had better quality control because,Honestly I haven’t experienced any issues with the crank puller or wrench or socket,I’d have to say that if you’re on a budget and can’t afford park tool brand tools,then this is a really good quality option.

Ich habe dieses Werkzeugset verwendet um die Kurbeln und das Innenlager am Fahrrad meiner Freundin zu entfernen (habe ihr einen Kettenschutz montiert). Das Werkzeug ist sehr gut verarbeitet, kaum zu glauben dass man nur so wenig dafür bezahlen muss. Das Abziehen der Kurbeln hat einwandfrei geklappt und die Verzahnung der Nuss zum Ab- und Anschrauben der Tretlagerschalen hat optimal gepasst (kein Spiel). Volle Kaufempfehlung!
