I have a set of nitto noodles that were involved in a pretty hairy over the bars crash that resulted from a failed front wheel. I thought for sure that they were bent and went to the trouble of finding a replacement, a 3ttt maes bar that I think i’m going to be less partial to. Now that I have the bars off, though, I can’t find any evidence that they’re bent. I’ve been over them a fair bit with a couple of straightedges and a level. In all of the places that they’re out, they don’t seem to be any more out than the 3ttt’s are. In other words, the variation between the left and right sides seems to be within what someone might consider normal manufacturing tolerances.
Would it be ridiculous to chuck these bars? Or, would it be risky to run them? With high quality aluminum bars that have been in a crash, where is the dividing line between prudence and wastefulness?
I’ve had a pair of Nittos suddenly break at the stem without any sign of them being damaged.
Can’t say I woudn’t use them in your situation though since I’m currently riding a pair of 3TTTs with an as doubtful past. What kind of riding will you be using them for?
Thanks for the advice all. I tried riding the bars around with no tape, torquing on them, etc. I felt a great deal of Zen but heard no creaking so i think i will go for it.
If the aluminum isn’t bent in any significant or detectable way then you likely didn’t exceed the yield strength from the force of the impact. The life of the bars might be shortened to some degree, but it’s likely not significant. It’s your well-being to consider, but if they were mine, I’d ride them and inspect frequently for cracks. If no cracks develop after some use, then I’d stop worrying about 'em. If you can find cracks, toss 'em.
