is my handlebar still safe?(8 posts)

is my handlebar still safe?colker

scratched severely with quill stems while trying different fit (didn't have open face stems around). it's a 320gr deda handlebar. the scratches took not only paint but some alum. in the bends. it was not an expensive bar but i would rather not buy a new one.

It could be point for breakage to begin. I just met a guy in a bike shop who went endo when his 3T bars failed up near the stem. I would not risk it. Aluminum is not great stuff in these situations.
Impossible to answer w/out seeing itcory

Maybe not even then...I have an old Scott AT-4 (sort of like bullhorns) on a beater. I scratched them when I put them on six or seven years ago, and every time I think of it, it worries me. But I've been riding it six or seven years with no problems.
On the other hand, if it ever breaks, I'm really going to wish I'd thrown them away and spent another 40 bucks or whatever it was.

Handlebars almost always break at the stem. Every other place they just bend over a large area. There wouldn't be any stresses that wouldn't find the handlebars weakest at the stem clamp.

Right under the stem most handlebars are butted up thicker or have a sleeve to scratch up, protecting the bar from cracks starting. Cheap bars surely aren't as granularly dense or as strong as expensive ones, so they would be more susceptible to cracking. If you can't trust them, replace them for peace of mind. Or if they still feel stiff, go with them.
this bar is made from a soft aluminum alloy...colker

it's the heaviest of the deda line thus supposed to be beefy... i guess. will probably buy another bar soon but emailed deda, curious to know what they will respond. now i'm convinced that open face stems are better. btw, it was a nice itm eclypse and it's 26.0 clamp is way smaller than deda's 26.0 bar.

Really. Just buy a new one.

Why have to worry?

A scratched up ol' Deda is not worth the hassle yer putin' y'self thru.

Just buy a nice Nitto or Salsa or Cinelli or whatever, and let the sun shine and the birds chirp, and all will be well again.

Turn the Deda into a hat rack or somethin'.

Really bro. Life's too short for this sorta thing.

A. (No, really, go buy a new bar.......For real......Today......Now......Really.)

at a a guess i think the bar is fine but you would know better than us.

on the itm ecypse - its tres importante to use the stem bolt expander when moving or fitting the bars; especially as you have 26.0 bars and the stem diameter is 25.8. open face bars are easier but in my experience the old single bolt clamp style like the eclypse is assuredly more solid and stiffer in terms of setup. the downside is that a little more care and effort needs to be taken when fitting or changeing the bar setup. if you have lost the expander ill happily mail you mine - it makes a biig difference.

with regards to bars - i weigh between 165 and 180 and have been super happy with the itm super italia 225's. they arent that common but there is one ebay vendor that regularly (once a week) posts them for sale at very reasonable prices. he also seels stuff off ebay for no additional shipping at very good prices (ie tires).

my advice is if you are concerned buy a new set of bars and post your email and ill send you the expander bolt.
0.2 mm of bar diameter width isnt a lot but if you rush it or dont have the right widget it can easily stuff up your bars especially if they are a 26.0 size going into a 25.8 stem.

many thanks! indeed, i don't have the expander bolt and neither does the lbs that sold the stem!
tried two eclypses,110 and 120, for fit purposes and one couldn't even tighten the bar. it was so "expanded", the bolt wouldn't fit the thread anymore. the borders of the stem clamp are sharp steel and cut the aluminum of the bar. i had the eclypse on another bar with a harder finish, less severe bends and it didn't happen.
again, many thainks on the stem expander,man. problem is... i live in
not too many equipment options around although some stuff is cheaper than in the us: i bought those stems for $20 each. those itm bars are not sold here right now. i saw them on a bike and it's pretty!
