If you look at titanium frame bikes on the web you can see their warranties. Most have very long or life time warranties that cover everything but crashes and deliberate damage to the frame. So I would assume this frame was involved in a crash. There are three types or cracks in titanium frames (from best to worst): Weld crack seam crack (titanium comes ...

It is very likely that you are putting too much stress on the frame when you are cycling due to your power stroke. It took me a long time to train myself to avoid standing and powering the bike through the acceleration of starts, or even powering through it while sitting. I've long since learned that while I have plenty of power, I actually am able to ...

There are certainly techniques that will put unusual strains on the bike, track stands could be, I certainly think that excess use of a turbo trainer does. I (try) to do track stands where possible and my commute bike (~150k per week for a number of years) only died when I crashed it ... Quality of the ingredients is certainly one factor. Another could be ...

I had a run of bad luck with road frames quite a few years ago, going through about three in rapid succession. Like you, the faults were always in different places. Since then I haven't had any troubles, but I did start using a slightly higher upgrade of frame materials. I currently ride about 120K a week,mainly commuting, doing track stands wherever ...

I think this question has gone a while without an answer because it's a little unclear what you want to do... do you want to do it yourself? Or by 'experience with welding' do you mean 'experience with having welded'? Either way, I don't have an answer for you, because I don't have direct experience welding titanium, nor do I know any welders in NJ, but I ...

I broke two steel frames in different ways, but both were used for commuting under heavy loads. I stretched the rear dropouts of a frame built for a 7 speed hub to fit a 9 speed hub, and this put stress on the chain stays just behind the rear bottom bracket. After about 6 months of daily riding, the right chain stay cracked. I rode my bike head on and it ...

Am I looking at the right thing? The little line running across the seat tube about 1cm above the bottom bracket? It's hard to say, but personally I'm not sure that's a crack at all. It looks more like a scratch. I say that because: a) it looks shallow, and b) that is a really, really weird place for a crack to occur. There are four types of stress ...

Riding without enough seat post in the bike is a real problem. Not only do you increase the mechanical advantage of the seat post against the seat tube but you put stress where the bike was probably not designed to take stress. And you are putting stress in the area of the top tube and seat stay. You state you have been riding with a longer post. Have ...

You're better off getting on the phone to FSA as opposed to asking your questions here. If it's a common problem they'll be the ones to know and they'll likely be eager to set it right. I can tell you that I've had no such problems with my Gossamer cranks in many years of ownership. If I were to speculate I would say that that is a defect and if the cranks ...
