Which External BB Tool
I am new to external BB and a friend has asked that I install a new FSA
BB and compact crank on his bike. So I am looking for a tool. I see two types: one is a socket-driven cup like this http://cgi.ebay.com/Park-BBT-19-Bottom-Bracket-Tool-External-BB-Tool_W0QQitemZ360097425999QQcmdZViewItem?hash=item 360097425999&_trkparms=39%3A1%7C66%3A2%7C65%3A10%7 C240%3A1318&_trksid=p3286.c0.m14 and the other is more like a traditional wrench like this http://cgi.ebay.com/PARK-TOOL-BBT-9-EXTERNAL-BOTTOM-BRACKET-TOOL-NEW_W0QQitemZ320295603121QQcmdZViewItem?_trksid=p3 286.m20.l1116. The socket-driven one seems like it will permit use of a breaker bar or torque wrench (not that I have ever torqued a BB before). While the more traditional wrench looks like it may stay on the cup better as the lever arm will not be offset to the outside (which seems to me will encourage the tool to slip off the cup under torque) but has a smaller lever arm. I really only want to buy one tool (really don't want either). So your comments are appreciated. |

I really only want to buy one tool (really don't want either). So your comments are appreciated. I'm happy with a socket type tool. After having some cranks installed by the LBS who I saw used no grease and no torque wrench, then discovering them loosening and ruined, I don't mess around with things around the bottom bracket area, and follow the installation instructions to the letter. They give a torque value, I use the torque wrench. It seems to be more critical for external BB interfaces. Note that a breaker bar can angle more than 90 degrees, which puts the lever arm back in line with the cup so that it doesn't rotate off. -pm |

My vote goes with the socket driven cup because you cam use a Msomething bolt with a few washers to hold it onto the BB(assuming the BB is threaded of course[1]), then it *wont* slip and you can use whatever lever you think will work and have to hand. I use this method to remove traditional BBs, works a treat. [1] If it isn't then I'm sure a G-clamp or similar will hold it. Mind you, I've no experience with these external ones, but I know the puncture fairies weld the traditional ones in place during the night shifts. |

I use this method to remove traditional BBs, works a treat. I do this with square taper BB all the time and it works great. Of course, doesn't the bolt go through the square hole where the socket snaps on? One is then forced to use the hex fitting (if there is one). |
