I didn’t want to spend to much on a tool, that I thought I would only use only once. But pleasantly surprised at the quality.I’m not very mechanically minded lol, but I’ve used the crank puller five times now (to strip down our old family bikes, that were rusting away in a leaking shed)It worked on bikes that were seized up, and it was easy to remove the crankset (I used a old seat post on the spanner part for more leverage, and it worked like a charm) YouTube channels recommend doing this with any brand of crank puller.For clarification I haven’t tried it on the bottom brackets, as oxidation had accrued between the aluminium and steel.I’ve got no hesitation in recommending this to remove the crankset, I’m already looking at other bike specific tools from this brand.

Did a bit of research on taking off bike cranks and pedals never having done it before and found these tools at a fair price , wasn’t sure about the Allen/Hex key as none of these advertised gave the size ,it is infact 8mm and fit my crank spindle perfectly to remove the centre, then the removal tool wound the actual crank off using a small hammer to tap the spanner around. All in all did the job admirably and within 10 mins both cranks removed , well worth the money

Perfect ⭐⭐⭐⭐⭐

Used on several bikes and it's been perfect, good value, good quality for the price.

For a beginner the lack of instructions didn't help, but after research I found out how to use it.

I needed to remove my crank to replace a magnet disc on my ebike. I'm a novice when it comes to bike maintenance so was hesitant when ordering this kit. I didn't need to be as I watched a you tube tutorial then carried out the task with ease. Didn't need the socket thingy or the hex key, that in particular will come in handy at a later date. Highly recommended kit

The crank puller removed my very old crankset without any problems, and very little effort. My bottom bracket was stuck fast and took a lot more effort, but the tool & allen key were up to the job. Installing the new bottom bracket & crankset was easy using this set of tools. Very impressed!

For powerspline + truvativ (blaze) cranks. The bits work, but you might have trouble with the bottom bracket if it's old. Even with a new bike installed properly, and I think you'd struggle just with the Alan key. I engineered a crude solution with 2m piece of wood to get more leverage, but also to be able to push down on the other side too to keep the bit from popping off - worked a treat. No issue taking off the cranks.
