I bought a cheap no name tool and the tooth profile was not fitting to remove the lockring on my centerlock disk brake even if it was the same number of teeth and diameter. So I decided to pay a few more dollar to get the original and it works.

Does not damage or mark the bottom bracket cups; It fits perfectly, better than others made of steel, and being softer, it does not mark the pieces. In addition, thanks to its precision, the notches are not damaged, and it is perfect for use with a torque wrench. The drawback is the price, but it is cheaper to use this tool than having to change the bottom bracket cups every time you have to remove them.

No estropea ni marca las cazoletas de pedalier; encaja a la perfección, mejor que otras de acero, y al ser más blanda no marca las piezas. Además, gracias a su precisión, no se estropean las muescas, y es perfecta para usarla con llave dinamométrica. La pega, el precio, pero es más barato usar esta herramienta que tener que cambiar las cazoletas del pedalier cada vez que hay que quitarlas.

Excellent quality like all park tool products, in my case I bought it to use it together with the dynamometer and tighten the centerlock disc fasteners to their tightness.

If its primary function is to unscrew and reassemble external Hollowtech 2 bottom bracket bearings, it has also been designed for Centerlock disks. Indeed, since the arrival of the traversing axes, the centerlock discs tend to be screwed on the hubs thanks to rings with Hollowtech 2 imprint. The Hollowtech 2 flat keys do not make it possible to screw to the torque (generally 40 Nm, that is is written on) CL rings. It is therefore necessary to use a socket with square imprint to mount a torque wrench. All Hollowtech 2 sockets do not allow this, because often the 16 teeth are bevelled, and hang badly fine rings CL, see not at all. This Park Tool BBT 69.2 bushings have been designed for this: the teeth are flush, and the bell is deep enough to accommodate the hub axle if necessary. Advantages = This socket is therefore suitable for crankset and centerlock hollowtech 2 rings, tightening to the prescribed torque. Disadvantage = The price, as often with Park Tool.

Si sa fonction première est de dévisser et de remonter des roulements externe de pédalier de type Hollowtech 2, il a également été pensé pour les disques Centerlock. En effet, depuis l'arrivée des axes traversants, les disques centerlock tendent à se voir vissés sur les moyeux grâce à des bagues avec empreinte Hollowtech 2. Les clés plates Hollowtech 2 ne permettent pas de visser au couple (généralement 40 N.m, c'est écrit dessus) les bagues CL. Il faut donc utiliser une douille avec empreinte carrée pour y monter une clé dynamométrique. Toutes les douilles Hollowtech 2 ne permettent pas cela, car bien souvent les 16 dents sont biseautées, et accrochent très mal les fines bagues CL, voir pas du tout. Cette douilles Park Tool BBT 69.2 a été étudiée pour cela : les dents affleurent, et la cloche est suffisamment profonde pour accueillir l'axe du moyeu le cas échéant. Avantages = Cette douille conviendra donc pour les pédaliers et les bagues centerlock hollowtech 2, en serrant au couple prescrit. Inconvénient = Le prix, comme souvent avec Park Tool.
