Quick question on external-bearing BBs: Are they all compatible? Are the
shaft diameters and spacing of these integrated cranks the same? I haven't worked on enough of these to find out by myself yet. I have a Shimano FC-R700 crankset, and someone near me is selling a set of Zipp ceramic external-bearing BB for cheap, but need to know if the two are compatible before putting my money down. |

Don't know much about Zipp bearings, but if you want the ultimate in external bearing bbs, check out the new Phil Wood: http://www.philwood.com/BB-Outboard%20Set.htm |

I don't believe outboard aluminum cups would last long, considering that steel inboard cups destroy steel frame BB threads in longer use, an experience I had after more then 150000 miles. If a tightly installed steel right hand cup (made of bearing hardened steel) can eat up steel BB shell threads, I believe that aluminum threads will be eaten by fretting in a steel BB. I don't know what an aluminum BB would do. Jobst Brandt |

This ain't your mum's crank format. Exploded views are not as good as a cross section drawing, but then we are all proud of our 3D CAD systems and need to show them. Jobst Brandt |

Isn't that a bit like getting a saddle for an epileptic horse? Sooner or later there will be other issues. Chalo |

The one I made has been fine for the last nine years, despite accumulating enough miles to wear out one set of very large cartridge bearings: http://picasaweb.google.com/chalo.c...782846418368274 Upon extracting the cups to press in new cartridges, I found the threads and BB faces to be in fine condition. The stainless steel spindle was only mildly burnished where it rode in the bearing inner races. Chalo |

I don't think there's anything wrong with throwing down for a new BB for an old frame. Heck, I'm currently trying to figure out if I should ride a Mountech-equipped MTB as-is, or replace the rear derailer as a preemptive measure. -- Ryan Cousineau rcousine@gmail.com http://www.wiredcola.com/ "In other newsgroups, they killfile trolls."

It's not oldness that is the source of the problem, it's Fwenchness. You can lay down a bundle for a BB, cranks, and pedals to make that smelly, leg-humping little dog learn a new trick or two, but the next thing you know it will want a headset, which will then make you find a new fork. Then it will be a seatpost in 23.7mm or whatever ungodly obsolete size, and then-- joy of joys-- the freewheel turns out to be Fwench (and worn out). Pretty soon you've spent a small fortune, more than enough to get a real bike. But it's still a peculiar, smelly, leg-humping little dog that probably has more bad surprises in store. Life is too short to suffer Fwench bikes or 26 tpi Raleighs. At the first appearance of trouble, they should be recycled. Better yet, don't even wait for the first trouble to appear and risk developing an affinity for an inadvisable machine. Save yourself and several other people a whole lot of trouble and cut the bastard up before disposing of it. Chalo |

Don't think they are compatible. Use a shimano BB, and when the bearing goes south, have a competent bike shop replace those bearings with Phil bearings. Ceramic(hybrid no doubt), unless the same price, isn't a good place to put your $, IMO. |

My old Peugeot mountain bike, from the top of their range in the late 80s, early 90s, was not well fitted to me (as I now realize), but in the ten years the original parts lasted I became awfully attached to it. It only showed its unattractive side when the original best quality parts wore out and, as you say, no new parts of equivalent quality were available. Then, within the short span of two years, it became an unreliable nuisance and my annual riding distance was almost halved. I gave it to the LBS for the goodwill because my next bike was bought from overseas by mailorder; he fixed the Peugeot and it still goes in the hands of its new and obviously proud owner (he's always all smiles when I meet him on the road), who may think that parts that wear out in two or three years are acceptable. But, I'll tell you what, I don't think many modern bikes will outlast that Peugeot. Reason: the they have a semi-integrated headsets, and I think those will wreck the head tube before the rest of the bike wears out. My Trek also has a semi-integrated headset, and I carry a short, lightweight Park headset spanner bolted behind my water bottle, and have the headset adjustment on my shortest cycle of routine maintenance; in fact, it is the only item on the 3-monthly maintenance schedule as the totally enclosed chain gets checked and waxed only every six months.
