Does this compromise handlebar strength?(4 posts)

Does this compromise handlebar strength?Shultzman

I picked up my new bike last week; and after riding it a couple of times, decided to lower my STI levers on the bars (to shorten brake lever reach in the drops).

When I unwrapped the bar tape, I noticed a cut in the bar finish around the circumference of the bars where the tape ends. It looks like whoever built the bikeup, used a razor knife to trim the tape edge.

These are Deda Newton 31.8 bars, and I wonder if these cuts in the finish are dangerous. Seems like I read an article a while back that said these type cuts in lightweight aluminum bars can start a stress riser.

Should I be worried?

Thanks,

Bill
Yes, it does!Alexx

Bring it back IMMEDIATELY to the bike shop, and have the bars replaced. DO NOT RIDE ON IT!!!
(BTW, this is a prime example of the lowering of standards in bike shops today.)
If it bugs you...DrD

I would go back and address it with the shop if it realy bugs you - realistically, while aluminum certainly doesn't react well to having sharp notches in it, a superficial scratch through the finish is not going to be a problem (despite what some of the realatively paranoid posters have said thus far) - if the scratch is very deep, well, then that's a different story! (if you drag your nail across the scratch, does it get caught in it? If it does, I would bring it back - if it's just through the finish, I wouldn't worry about it as a safety issue, and would only bring it back if consmetically it will bug you. Most bars are 1.2mm+ thick around the stem clamp.)

the etchings. (Contemprary road bars ARE still etched aren't they? Or of that just a retro thing?) At any rate, you can pretty much assume bars wouldn't be etched so deeply as to compromise safety, and I'm guessing the razor scratch isn't nearly that deep.
