External-bearing BBs?

Andre Jute wrote: A good French bike with the best French parts will have plenty of time to ingratiate itself. My old Peugeot mountain bike, from the top of their range in the late 80s, early 90s, Chalo wrote: If I understand correctly, Peugeots had gotten with the program by the time MTBs were the dominant bikes on the scene. If that's true, then there is nothing wrong with a Peugeot MTB versus another sort of MTB from the same time period. Same with Raleighs; they gave up using proprietary thread standards by sometime in the '80s, and after that their main problems were aesthetic. French origin is never a problem per se; it's the French thread system that French manufacturers insisted on using long after it constituted a disservice to themselves and their customers. All the "wonderful" French road bikes of the bike boom years were thus afflicted. And if some misguided parts manufacturer had seen fit to make French-threaded parts all this time, the French thread folly would have been nothing more than a source of confusion. That didn't happen, though. French- threaded headsets, BBs, freewheel hubs, pedals, etc., are all unavailable historical curiosities that render their respective bikes practically unmaintainable-- $120 bearing cups for $400 cranks notwithstanding. The revival of the obsolete French 650B tire and rim size by Rivendell looks particularly foolish to those of us who worked in bike shops in the '80s and '90s and had to break the sorry news to customers that their otherwise perfectly decent bikes couldn't get routine repairs at a reasonable cost. Good summary. Several European brands sold regular Asian bikes, rebadged, both road and MTB models, in various years for the US market. Raleigh's Nottingham bikes were 26tpi right to the bitter end. By that time [1985], the US models built at Nottingham were down to pretty much only Sports and DL-1 Roadsters[1], other bicycles being mostly Taiwan ROC by then. [1] Team Pro, Pro and Comp were built at the Carlton shop, not Nottingham -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 ** Posted from http://www.teranews.com ** |

I don't think there's anything wrong with throwing down for a new BB for an old frame. 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.

Save yourself and several other people a whole lot of trouble and cut the ******* up before disposing of it. Chalo Oh, no argument there...95% of the value in my PX-10 (updated with a full Campy Centaur group, aside from the PW BB) is sentimental, since I've had the thing since I was 13 (I turn 35 next month). For so many years, I built up in my head what a great bike it was, I was kind of taken aback when I tried out bikes with, well, BETTER geometry than the parallel 74s of my PX-10. I don't see myself ever getting rid of it, but if something happened to it, I'd happily replace it with a Mercian King of Mercia to fill my "lugged Reynolds classy European bike with room for fenders & 28mm tires" slot. |

Quick question on external-bearing BB's: Are they all compatible? Are the shaft diameters and spacing of these integrated cranks the same? Â*I haven't worked on enough of these to find out by myself yet. Â*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 BB's, check out the new Phil Wood: Â*http://www.philwood.com/BB-Outboard%20Set.htm I don't see what holds the spindle and what sort of spindle fits that assembly. Â*I also doubt what the free-fit aluminum sleeve and a free fit (no taper or press) spindle that seems to fit in that sleeve won't fret giving a grinding squeaking BB. Â*I think PW would do better with a cross section view of the assembly than a shiny photograph with inadequate words to explain what the selected view shows. OK, presuming the outboard bearing is from the Zipp VumaQuad crankset, how about checking out the installation manual, which does show the spindle interface: http://www.zipp.com/Portals/0/Produc...ank_Manual.pdf Oh, this shows the Isis crank interface, which is dead anyway because it is a flawed design based on the wrong assumptions about steel-to-aluminum interfaces. We have also read about spindle failures, here in this newsgroup. However, the endless pdf does not show what locates the spindle in the bearings, radially or axially. -- Jobst Brandt |

In fairness to France, the Internet has made it a lot easer. To sum up: YST universal BB, $20. Headset: ISO 1".

Save yourself and several other people a whole lot of trouble and cut the ******* up before disposing of it. Can't do that. I have already sold off a Peugeot, a Raleigh, and a Motobecane (might have even had Swiss threads) in the last few weeks. All the frames (along with an Ascente Prolite with triple-fade paint) sold for cash and parts (new 165mm MTB cranks, woot!) which I will either put on my bike, put in my pile, or turn into beer. I turned French and English bikes into beer and MTB parts! You hear that, Chalo?

I disagree, its not only Rivendell pushing the 650B (584mm) wheel size. For example, QBP, arguably the largest parts distributor in the US is pushing the 650B Bleriots Apparently, the Bleriot (a joint venture between Riv and QBP) has an appointment with the guillotine in the next few months. It will be joined in hades by the "650B only" Saluki, it's over-priced brother-in- folly. In the future, the Homer-thingy will be 700C in larger sizes and 650B in smaller sizes (at least until the hobbits work off all that unsaleable 650B rim and tire inventory). For once, Barnum was wrong!! :-) |

Again, there is no indication of what locates the spindle radially or axially, just technical sounding text but no engineering answers. Without a radial press fit the spindle will fret and creak in use and I have no idea what holds it axially. Rather than show a cross section through the assembly, we get an exploded view that shows none of the important functions. This suggests that either they are hiding something or assume the customer is incapable of understanding a drawing rather than a 3D image. Jobst Brandt |

With the weak US dollar, Rivendell appears to be consolidating its lineup and will be offering 650B on its next batch of small AHH (58cm and smaller), mixtes - yes, those are still alive!, and on the highly anticipated Bombadil MTB. Further, as I stated above, Soma is getting into 650B and plans to have a frameset, and associated wheels/rims/tires out soon. Moreover, Kirk Pacenti has come out with an entire line of mtb components, including shock forks, tire and complete wheelset, for the new 27.5" wheel: http://www.bikelugs.com/store/index.php?intCategoryID=3 This may be what is needed to make 650B mainstream!

Now put 32mm tires on 622 and we have a bigger wheel again. Bigger wheels really are better. -- Michael Press |

That's 32 on 622.--and you're right, it's better than just about anything. But that's not the point. It's a Schick and Gillette sorta deal. |
