Posted on 8th, October 2010 about Hollowtech 2 Socket Tool
The socket tool makes a solid impression right away. It's steel and has a 1/2inch wrench drive interface. It is more compact than the Parktool socket, thus puts the wrench interface closer to the cup and helps prevent the whole thing from angling out and slip when torque is applied. This together with the a better fit than the parktool socket results in markfree cups during install. Due to the external cup only design it is worth pointing out that with e.g. Howitzer BB, with the axle sticking out, this socket doesn't work. i couldn't find anything wrong with it if this socket was 15 or 20 GBP, but for this price it's a bargain!
