BBB Kurbelabzieher Power Pull

Excellent delivery time. Good quality lot better than the cheaper ones works perfectly.

I’d like to say, I’m a total novice with bike repairs. My daughter’s chain came off and we wedged between the front crank and the frame. 2 hours of effort left me with nothing but sore and filthy hands. I figured I’d need to pull the crank out a little to loosen it. I did what most inept dads do pull, strain and curse.Had it not been for all shops closed because of COVID-19 and the prospect of the kids not even able to go on their bike I would have thrown the bike in the van & taken it to a bike shop.I didn’t know until I googled the problem that you needed a special tool to pull the crank out.Then I nervously read the reviews where people had stripped threads and effectively ruined their bikes.I was not confident!!I carefully studied the pictures on the card. Removed a section of the tool for my ‘square tapered crank’ (who knew?)Then wound it in with a 15mm spanner and tightened the bolt with a 14mm socket. It slid out, I released the chain (using gloves this time) and tightened the bolt back up.I only flipping did it! Wow, big smile (reestablished credentials as hero dad who can fix anything- title lost some 6 years ago!)Fantastic worked so well - I also don’t usually write reviews but I was so chuffed I did it and well, I have a little more time on my hands.Thanks for a simple easy to use tool.

Great little tool feels well made and very strong. First time I’ve ever done a crank pull there is a really useful Halfords video on this explaining how to do it.The most important thing is to make sure you screw the crank puller in fully. Otherwise if you only have it screwed in a bit it will sheer off the threads of the crank and pop out. Then you are doomed.Very simple once you know how and this tool is great and well made.So to be clear on steps.... You have to rotate it to retract the pin bit As far as possible -then fully screw it into the crank then rotate the pin bit with a Spanner which pushes the crank off the bike.There are diagram instructions and they are ok ish. Good luck.

Well built and good value. HOWEVER: Has a pivoting end on the pusher rod which is wider than the narrow end of the square tapered hole on my cranks. Didn't notice this when I tried the first one and ended up stripping the threads of my crank. Winding the pusher all the way out removes this pivoting end leaving a narrower section that passed through the hole and worked just fine to remove the crank.

Good quality item. However, the instructions could have been a bit clearer in one respect. Pictorial guides are useful, but sometimes adding the odd word makes following them more useful still. On first attempt at removing my old crank, thinking I was closely following the guide, I started to strip the thread. This was because it is not really made clear that you need to open the main bolt by fully loosening it, before you attach the puller. Otherwise the device will not penetrate the crank arm sufficiently and possibly start to strip the thread. Luckily, I noticed before inflicting too much damage. I admit this is a silly novice mistake; but this is basically what I am. However, I'm sure I am not alone in making the mistake described, as I have seen other reviews of similar devices where individuals have managed to strip cranks. Be careful when using the puller for the first time. GOOD tool when used correctly.

No need for anything more expensive, and anything cheaper might not be machined to the same tolerance which can cause damage.This tool was exactly what I needed for removing Shimano Octalink cranks without causing damage.Make sure to unscrew the inner part before inserting the outer, and make sure to insert all the way before using the inner part.Mine was a little sticky with manufacturing grease which was easily removed with soap and re-lubricated with a drop of oil.

Please use with care on an alloy crank, it stripped my threads !!!

Take your time with this tool and it works perfectly - clean out the thread of the existing chainring with chain cleaner till it’s like new and then a smear of assembly grease or Vaseline etc as u wind it in until the thread of the tool is fully in (u need to make sure the inner part is retracted to do this) and then simply turn and it comes away ...I think any of the negative reviews are people who didn’t do this - great little tool

La herramienta cumple con solvencia su cometido, que extraer las bielas de la bicicleta.No voy a polemizar si hay otros útiles de mayor calidad, por el precio que pagas es más que suficiente para un uso "particular".Esta en concreto es válilda para diferentes tipos de biela ISIS, Octa, Square...La herramienta es sencilla de usar, con la bicicleta en un sitio estable, ya sea en el suelo o en un soporte. En la parte trasera del empaquetado encontrarás unas instrucciones de uso, que no son otra cosa que la forma de usarla en función del tipo de eje de la biela, hay una pieza al final del tornillo que tendrás que sacar con la mano.De forma general para extraer la biela, tendrás que:1- Quitas los tapones de los tornillos de la biela, si los tiene.2- Si en mantenimientos anteriores no tuviste la precaución de untar con grasa de montaje el eje de la biela, rocia el eje de la biela con un poco de lubricante en spray, tipo 3-1, WD40... (y no, no se te va a disolver la grasa de los rodamientos porque no llegará.... hay que añadir un poco de lubricante... no bañar la biela)3- Unta con un poco de grasa tanto la rosca de la biela como la rosca del útil, esto hará que enrosque más suave.4- Asegurate que has enrroscado hasta el fondo el útil ya que el algunos casos tendrás que aplicar mucha fuerza para extraer la biela. Se trata sólo de enrroscar hasta el final, no hay que apretar.5- Te aconsejo usar una llave inglesa, ya que el agarré será mas fuerte y ejercerás mas fuerza. Si todo va bien al ir apretando el tornillo, la biela irá saliendo.Yo la recomiendo para trabajos esporádicos y caseros ya que por calidad y sencillez.Saludos.

Utilisé pour sortir des manivelles avec un axe "carré" ou standard. Fonctionne parfaitement. Robuste.

今回使った自転車のシャフトの太さが少し細く、この工具の飛び出し部分が直接シャフトに当たらず、間に合わせに手持ちのボルトをスペーサー代わりにして作業をしました。

Sicuramente la qualità non è delle migliori ma per un uso non professionale vanno più che bene. Diciamo che per il prezzo pagato la qualità è adeguata. Io ho tolto già 8 pedivelle e non ho riscontrato alcun deterioramento come riportato in altri commenti.

Demontage meiner extrem festgefressenen Vierkant-Kurbel ist gelungen. Ich hatte fälschlicher Weise beim ersten Ansetzen vergessen den Aufsatz für Oktalink-Kurbeln abzumontieren. Beim Werkzeug war nur etwas Lack runter, die Kurbel hatte es natürlich extrem verformt, da der 4-Kant tiefer liegt (steht nicht über) als die Gewindeführung der Kurbel. Dennoch habe ich es danach geschaft die Kurbel zu lösen. Dieser Fehler führte zu keinem bleibenden und Funktionsrelevanten Schaden, weder an Kurbel noch am Werkzeug.Bei der zweiten Kurbelseite (die Antriebsseite) habe ich diesen Fehler nicht erneut begangen, jedoch saß diese Seite noch fester auf dem 4-Kant, als der andere Kurbelarm. Der zuvor drehbar gelagerte Ring direkt unter dem Aufsatz für die Oktalink-Kurbeln ist jetzt nahezu kaltverschweißt (wie Rührreibschweißen :P) mit dem Gewinde des Abziehers. Allerdings weiß ich eh nicht genau wozu der drehbar gelangert sein müsste.Also alle Festigkeitswerte des Werkzeugs, mit dezenter Ausnahme bei dem Ring (wozu auch immer der da ist), sind mehr als nur überzeugend. Da haben sich an meinen Rollgabelschlüssel mehr Spuren hinterlassen.Werkzeug war wie alle Werkzeuge, die ich bisher von BBB bezogen habe, auch mehr als gut vorgeölt.Tipp: Wer ebenfalls Probleme hat, die Kurbel locker zu bekommen, ein Heizluftfön soll helfen und was definitiv immer gut ist, einen Tag vor der geplanten Demontage Öl auf alle zugänglichen Seiten des 4-Kants geben und seitliches Lagern, damit das Öl hineinlaufen kann. Weiterhin hat mir geholfen, wenn ich immer mit leichtem erneuten Anlauf die Schraubenschlüssel anziehe. Das heißt, ein Wechselspiel aus leicht Lockern und erneuten verstärktem Anziehen.Die meißten Werkzeuge haben harte Kanten, ggf. Handschuhe oder Putzlappen zwischen Werkzeug legen. Hilft auch die Risiken für Quetschungen, etc. zu vermindern.Zeitaufwand: 2h etwa bis ich die alten Kurbel endlich gelöst bekommen habe (leichtes vorheriges Reinigen mit einkalkuliert).14mm Maulschlüssel, Rollgabelschlüssel oder Nussschlüssel empfehlenswert^^
