Oumers Bike Crank Extractor/Arm Remover and Bottom Bracket Remover with 16mm Spanner/Wrench. Professional Bicycle Repair Tool Kit

The right tool for the job. This made a complicated job, easy.

This worked on my Shimano LX Crank! It is a small handle but, perfect to put in bike pack when riding. I had some other big bike pullers but were way too large for the Shimano's. I was hoping this would be OK, and was! I am happy I could get the crank off after 25 yrs. This time I am using Never Seize!

Great price. While the chrome kinda gives them a "cheap" look they feel rather solid. The crank remover tool worked just fine with no issue, screwed into the crank without a problem or hard to the crank. The BB removal tool is heavy and feels like good steel. Worked just fine taking the BB out of my fixie and putting the new one in! Did not damage the spindle or threads for the spindle bolts. These tools worked for what I needed and saved me alot of money. Even the little wrench feels solid, not flimsy or weak at all!

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.

Easy to use Worth every single penny

It worked well,

Tools are well built and fit and function is excellent. Crank puller and Bottom Bracket remover work great on the square taper cranks and the 12 pin Bottom Brackets! Check your BB pin count prior to ordering so you get the right one that matches your pin count. Just tuned up the bottom bracket on one of my bikes and these tools make it simple and easy.1/2" socket adapter makes it fool proof when using a ratchet for added torque. Can't beat the price and you might want to buy the set that has the rear cassette tool included as you'll probably need that tool at some point anyways for general maintenance such as replacing a busted spoke. With all the Utube video's available for pulling and installing the square taper cranks and bottom brackets, you can easily perform general maintenance and install/removal with these quality tools. Just one DIYS maintenance check will more than pay for these tools! Highly recommend.

Did the job and the price was right.
