Avenir Crank Puller

This crank puller works great. I've removed 2 square-spindled crank sets with this without any problems. I found it easier to just separate the two pieces of the tool, thread the black piece into the crank, then turn in the silver piece to push out everything. I also later realized that the back of the tool is a 14-mm socket wrench -- the usual size of the crank bolts. I would recommend this tool to anyone who needs to removes their cotterless crank set.

This tool works ok for removing BB's, I was disappointed at the massive allen wrench socket on the end which made the tool completely impractical for using on the end of an allen wrench (I think it is a 14mm or 16mm, something huge). Otherwise, if you were going to use a wrench anyway, it will perform the job. The design is apparently for using this end like a socket wrench to first remove the BB bolts.

Removed the crank on the non-drive side with difficulty. The tool sheared in half when removing the drive-side crank. It has a square pin pressed into the center of the tool that is poor quality. The threads need to be shallower to generate sufficient force on the tapered end of the bottom bracket rather than shearing force on the pin. The metal in the end of the drive pin is too soft and deforms the threads after use so it can't be removed from the collar. I don't imagine this tool would last very long with any use unless the cranks are very easy to remove.

Simple and easy to use. I've only had to use it twice so far. Threads are still holding up. Hope to get many uses out of it.

After trying to remove some pretty stuck crank arms, I ended up snapping this tool right in half when turning it. This changed my perception of buying tools: always buy the better quality tool.It did it's job in the beginning, but most would do better with Park Tools.

Great crank arm puller tool for square taper crank shafts. The tool is very well made and the center that presses against the crank shaft threads spins and is removable. I used this on a low-mid range MTB with a 3 piece crank and bottom bracket assembly, and the tool works great.

Got this to DIY reapair on the crank of my bike. Worked slick and was such a cheap tool to have in my repair kit! Would recommend it to anyone that has a working knowledge of bike repair!

Just the right tool for the job. I has to change out the crankset on my mountain bike and required this to remove the old crank. Worked like a charm.
