Following the usual discussion on another thread about which frame material was best etc I was wondering about what experiences people have actually had? In particular, I was wondering if different frame types were were maybe likely to fail in different places.
So in the poll please differentiate between breaks at the joint or in the middle of the tube itself? Thank you :0)
I went all out with my first bike back in 2000'.
It was a 2000' GT XCR-LE i-drive in GT Team race colors. The LE was for limited edition, the top of the line I-drive. It had Easton 6061 taper wall tubing and was hand built out of the Santa Ana plant. The frame material made the frame a whole pound lighter than all other I-drives. I had been pondering over a few different brands at the time and the I-drive system intrigued me. And then I came across an article about this impending model coming out and I was sold. I drove to Super Go in Oceanside / San Diego who were a GT dealer. I asked the manager about it and that I wanted one.
All the employees were dumbfounded none having heard of this model. They actually acted like I was full of crap.
I asked the manager to call up his GT rep and check on it. And sure enough the rep said that model is going to be available soon in a limited quantity hence LE / Limited Edition. I interrupted their phone call and said I want to special order one right now if possible. So that's what we did on the spot. The rep said it could take a couple months and I was fine with that. Three week's later they called me and said it was in. I hauled my butt down there only to find all the employees in the back drooling over it. It was the first one they had seen and first one shipped out of Santa Ana. They had a GT XCR-1000 [the next highest at the time] next to it comparing the two. Which weighed 1.5 LBs more. It cost me almost 4k which was quite a lot for a bike back then.
The BIG I-drive frame failure issue in the first I-drive designs.
They always cracked at the seat tower where the seat post inserted into the frame on the front.
I ended up cracking two frames and the second one happened right after the GT bankruptcy of 2001'.
The first frame cracked exactly 6 months in. They warranted it with a replacement frame. They said it was the last LE frame left. I got lucky on that one.
The second frame cracked exactly 6 months later [see a pattern ].
This time it cracked right after the big GT bankruptcy of 2001'. This time I was S.O.L. On getting a new replacement warranty frame.
But I did luck out in that Super Go stepped up and offered to give me $600 towards any frame they had. I didn't have a choice GT was done with. So I went with a $2K INTENSE UZZI - SL frame. Which I had them switch as many parts over from my cracked GT LE frame. I ended up purchasing a new $650 FOX fork and $450 Hope brakes. I spent a pretty penny that day "again".
2 frame cracks in 15 years of riding is not bad.
Here's the frame that I was referring to.
And a photo of the area that cracked. They always cracked at where the seat tube entered the frame on the front side. Which this photo doesn't portray.
By the way my both of my cracks are not listed. They are one in the same.A seat mast failure.

Top two wierdest cracks and not on that list were the external bottom headset cup and a fork dropout. The external portion of the headset separated from the internal pressfit portion..that was @ 2 yrs ago, and this year 20mm fork dropout cracked pretty good
After seeing these, I'm not sure I want to keep handlebars longer than 4 maybe 5yrs...
(1) 1996 Y33. Aluminum to carbon crux junction. Known weak point. Noticed failure in 2013. This bike was used, abused and flat out beat. It was flipped and crashed into and onto some serious rock gardens, and has chips in the paint that dug into the carbon fiber. Again, this bike was used WELL beyond it's design. It raced downhill and won many races in the mid 90's.
(2) 2008 Fuel EX9. Aluminum "seatstay" swingarm. Broke in 2009 I believe it was. Started a ride, suddenly the bike felt weird! Slightly rocky area. Not an abused bike, by any means. I had not been riding really since 1997, so I was trying to get back into shape. Did not ride it much.
(3) 2015 Remedy 9.8 Carbon, top tube. Riding uphill in a rooty section, and a nasty loud crack happened. Bought in March, broke just two weeks ago. Bike has 250 miles on it, and has not been ridden very hard yet.
I've had several "others"; all alloy: BB/seat tube joint, seat tube/top tube joint, head tube itself, strut in rear triangle (not really a seat or chainstay).
Also, I don't know how you'd capture this in a poll, but I've personally had 5 'others' that only get one count in the results, yet if I broke 5 frames different ways they'd each get one; for purposes of seeing what failure modes are most common, you're going to come up short.
