QKURT Lockring Tool, 8-Tooth Splines Bottom Bracket Tool Sealed Cartridge Tool Compatible with SRAM Truvativ ISIS 8-Notch Bottom Bracket Cups

I have an old bike that had an octolink bottom bracket that I wanted to take out and replace. This was going to be a one-time (most likely) need, so I really didn't want to spend a lot on a tool that I likely wasn't going to need again. This piece worked. It aligned perfectly with the 8 recesses of the octolink and I was able to use a plumbers wrench to loosen and then unscrew the tight bottom bracket. Solid piece, good fit, not too expensive. Checks all the boxes.

Working as expected.

It worked perfectly

It is a much cheaper version than Park makes, and for infrequent use should be fine.

Fits the bosch gen4 cx sprocket nut. Machined out of solid steel .

I could not be happier. I did not take any pictures of its use, but it was uneventful other than having to use an impact socket over the giant nut and an automotive impact wrench to take off the drive side!!! If you take a look at the picture I did take of the crank bolts, they snapped and I had to weld a nut onto them. That kind of gives you an idea of how stuck on everything was. The bottom bracket was in there tight as can be and this tool took it off with ease and did not make one little mark in the bottom bracket!!!! Two thumbs up! Thank you for an uneventful bottom bracket removal after a disastrously tough crank removal.

I needed an ISIS tool to remove the nut on my Bosch e-bike motor. This one worked fantastic at a fraction of the name brand offerings. Highly recommended.

Good quality feels durable and fit crank bolt was easy to use.

Fit perfectly and undid a very stubborn chain ring nut. No damage to nut or tool. Finish seems good too, excellent socket.

Entgegen aller Erwartungen passgenau und gute Qualität! Problemlos eingesetzt und hat Freude bereitet.

Bon outil qui m’a permis de changer sans encombre mon boîtier de pédalier. Il faut bien enfoncer l’outil et le sécuriser avec un serre-joint pour éviter qu'il ne bascule lorsque l’on force comme un malade ou moment du dévissage... :)
