This item should not be for sale.

This is the poorest quality tool I have ever used and it should not be for sale. It didn’t even last one use and has also damaged the crankset I attempted to use it on. I will be seeking a full refund along with the replacement cost of the damaged crankset.

Hi Brigitte, thank you for your review and for sharing your experience with our members across the world.

Can we request you to come back into our store and for us to check your bike? We'll be happy to refund you for the tool, and we'll need to examine the crankset to help you out further.

We look forward to seeing you, please let us know before you come by simply replying to this emai..

See you soon!

Btwin crank extractor

Does the job perfectly.

Only lasted the first use

I hadn't noticed that the threading was damaged as I unscrewed the tool after the first use, which was alright as thought that I only needed it the once, So when I used it the second time, no amount of turning would pop the crank arm off the crank set. Still good if you want to make your bike stop squeaking as you ride.

Happy customer

Just what i needed.

Sturdy and would recommend

This is a sturdy, great bit of kit; the handle is nice to hold and turn and it's easy to use. Not too big, I would recommend this for anyone.

Does the job

We needed to replace the left crank arm of our Triban 520 flatbar. This tool did the job easily - I love that it also has an "8mm-allen head". So it was the only tool we needed. The fact that it comes with a handle means you don't need a wrench. It may not be the tool for you if you own an 8mm allen key and you have a wrench, though - you can buy crank extractors without those two things for half the price. Anyway, very happy with this product!

Tut was es soll.

Funktioniert problemlos mit 4-Kant.

Sehr massiv, damit bekommt man die Kurbel ab


El material es muy sólido. Es fácil de usar. Su diseño es bueno, aunque para tuercas que están, casi enrasadas a la cara exterior de la biela, no es recomendable ya que no tiene pasos de rosca suficientes para hacer palanca y sacar la biela.
