|actually happened this year on BMB about ~480mi into ride..
is 480mi good excuse for unclean chain?

|Must have really torqued those cranks. Well done.
Sorry, just feeble attempt at lightening the mood.

|I guess that I also would like to see a pic of the legs that||bill|

|Must have been a Seven, Merlin or Airborne...|
|Yikes!!!!......please pass the warranty||jagiger|

|A word to used bike buyers...the warranty is not fo your life time, as they are not transferable (at least not for the Cannondale I picked up....if they say "they'll take care of you", check the site 1st!).|
|Looks like a Moots, what is it? (nm)||JS|

|pull the cranks!||alex the engineer|

|..and send a pic of the other side. I don't see a clear origin of the crack on this side. Maybe the other side will be clearer. Could mean the difference between a warranty replacement or not!|

|Looks to me like it started right at the edge of the weld (heat affected zone). that is the weakest part of the weld and the crack goes right through it on the pictured side. Is it a butted frame or straight gauge tubing?|
|not so fast!||alex the engineer|
Sep 13, 2001 8:48 AM
|the crack could've been directed along the edge of the crack. I see a dead-straight failure line there-looks like the crack "travelled" along that weld.|
|you're probably right.||vanzutas|

|If it started in the HAZ that is visible in that picture ther is probably no reason for it not to continue along that weld towords the back of the bottom bracket. Now I really want to see the other side of that frame.
Pull the crank, please!

|no this is not my bike I can't pull cranks off and I haven't seen the other side but I am guessing it looks similar if crack goes around on that side too.
I can speculate on how the frame failed. Cues:
- frame is at least 10 years old
- if failed on downhill (rider ~190lbs was standing)
- there're many potholes in New England
as far as I know frame was warranted and I would expect it was replaced if customer service is smart enough. Frame possibly had a few hundred thousands miles on it. This is the price for ultra endurance riding: frames fail
|Looks like a Seven? (nm)||_blt_|

|Not at 10+ years old. Maybe a Six? :-) nm||MikeC|

|once again do not blame Merlin as far as I know that frame crossed States at least once ;-)|
|Is that a touring frame?||Largo|
Sep 13, 2001 1:47 PM
|That would explain the triple, and perhaps explain the crack, that is, heavy loads+lots of miles.
Damn, and i thought Ti was forever!
Ti is an Uber metal, but even it has a fatigue limit.
|frame is road..||cyclopathic|

|this is "brevet" machine, hence triples.
yes also called "light touring" oppose to "touring" with cantis and enough clearance to fit fenders and 30mm+ tires
imagine climbing 2,000' gain hill with avg grade 10-12%
then imagine doing it 5 times
then put it in the beginning, middle and end of 750miler
and you get an idea what is it like and why you need triples
Most brevet riders ride 10-15K (and I mean miles) annually and occasionally break frames.
Al, steel, Ti I have heard it all break either in BB area or headtube. More about Ti and steel this would be ~95% of all randonnee frames.
All Ti frames I have seen/heard broke around welds maybe because they're not heat treated like some Al or steel frames.
I have Reynolds 520 steel frame with 25 year warranty.
I commute on it.
I ride centuries.
I ride brevets.
I am afraid I'll use warranty some day
