Cyclocide...
 
1 Attachment(s)
It's happened. My bike has been condemned to permanent garage living (I can't bear to trash her) by most every bike-master I've been to see. The head-tube crack in question is indeed fatal and the mixte-master will no longer ride the crappy streets of San Francisco. If everyone could do a trackstand or pour a little White Lightening on the ground for our dearly departed, I think she'd really appreciate it. Excuse me while I mourn for a little while...--End melodramatic scene...

:( Sorry to hear that. Do you know how the head-tube crack came to be?

Perhaps it could be a good opportunity for you to learn to weld. Some hardware stores rent welders, mine has both wire feed and arc. I don't know how to weld, and don't really know what those type of welders are, but they sure sound fun.

On a lighter note, what's your plan for the new ride?

katio 05-04-06 11:40 PM

I have a sneaking suspicion the crack is a product of oxidation and being thrown around on the train trip. I also talked to some people about welding it and it's possible that could fix it but it would probably just crack again. The wrenches pretty much told me to get a new bike though. I found a yellow PX-10 at the SF Bike Kitchen which is awesome because you can't buy a PX-10 for 30 dollars ANYWHERE. So in keeping with the esprit de corps, I think I'm gonna go french.

Be careful of going French. See what the threading is, if it French threading good luck.

My dad used to race (road) way back when, and he also worked at a bike shop. He built up several PX-10s and raced on one for a while. He loved them.

Is $30 the frame/fork or the whole bike? Either way nice deal.

katio 05-05-06 02:09 PM

It's only frame/fork but they're pretty lax on trading parts and kicking in maybe a few more bucks to keep some components. It's a full bike right now but I have some parts I think I want to keep. P-Son, it's definitely french threading but my last bike had french threading so I know the headache I'm about to encounter. I could get a whole new bb/crank set and not have to worry about the threading though couldn't I?

onetwentyeight 05-05-06 02:13 PM

yea but you need french threaded cups for the bb. which limits you to phil or sugino i think. or some vintage **** :)

prodigal son 05-05-06 02:15 PM

I think you can get French cups from Phil wood ,stronglight maybe TA specialties. There is also the issue of the headset. There is a person on here and he usually posts in the vintage section, Poughoumame or something like that. I believe he is a french bike expert.

katio 05-05-06 02:28 PM

Oh well it's a complete bike right now so I don't have to worry about getting any new components right away, which is awesome. Some Phil Wood might be nice though...

I'll PM that guy though and see what he has to say though, thanks.

katio 05-05-06 02:30 PM

Wait a second, wait A SECOND! Can I convert a PX-10 into a fixed gear??

You can convert pretty much anything into a fixedgear. sheldon brown did it: http://sheldonbrown.org/px7.html

Does it have horizontal dropouts?

iamtim 05-05-06 02:36 PM

Hey, wait, katio.

Is that a Motobecane frame? If so, I have a gray one sitting in my garage not doing anything; you're welcome to it. I imagine it is since the topic of French threading came up, you weren't worried because your last bike was French threaded, and I'm pretty 100% sure that the Motobecane I have just like yours is French threaded.

Interested?

schloe mo 05-05-06 02:36 PM

hey katio, sorry the mixte has to go. it was fun to see it, and you, in chicago.

katio 05-05-06 02:37 PM

No, they're a 45º slant

prodigal son 05-05-06 02:38 PM

That is fine then.

onetwentyeight 05-05-06 02:38 PM

those are horizontal drop outs :) http://www.velostuf.com/Campy%20Ti%20Dropouts%20I.jpg

katio 05-05-06 02:43 PM

Hey Tim, it's a Peugeot but I'm assuming the two frames would be near identical otherwise. I found another Peugot to take her place though so no worries but thanks for the offer.

And Schmo, el gusto es mio! Meeting you and Chicago was a very memorable experience. I had a feeling it was the end of the line for mi bici but I just had to show her a good time, a last hurrah if you will.

gorn 05-05-06 02:44 PM

Another idea for the BB/crank would be to pull what you had on the mixte off. If you go the fixed gear route you can remove one of the chainrings and replace the chainring bolts with single speed chainring bolts. It's possible you'd have chainline issues, but if it's on the inside of the spider you'll probably be okay.

katio 05-05-06 02:45 PM

Ooooh, campy! Can dropouts be changed? It looks like the end of those have some sort of thing goin on that would allow for it.

katio 05-05-06 02:46 PM

Hmm, interesting...

yes but it requires some brazing/welding. not worth the bother really. if you wanna put on new drop outs and make a fixed gear, might as well get track ends. totally unneccesary tho.

gorn 05-05-06 03:29 PM

Forkends 101:

There are three main types of rear fork ends:

Track ends - What you see on the fancy track bikes. Obviously these can be used for fixed gear, sometimes they are also used for derailleurs on TT bikes or something, but then there are brake pad alignment issues I think?

Horizontal Dropouts - What you see on older derailleur bikes. Including the PX-10. Though it's called "Horizontal", they really are at an angle as Katio noted. These can be used as either SS or derailleur. This is what my fixed gear has.

Vertical Dropouts - What you see on modern derailleur bikes. These are more painful to make into SS because you can't adjust chain tension since the rear axle has only 1 position.


Basically you'd have no dropout problems on the PX10
