    When to replace DH H-Bars????????????

    The title says it all.... My reason for questioning this is...after smacking a tree at nice high rate of speed that left my front (left) brake lever nice and bent...well it's not the first time I've smacked a tree with these bars, (I like hitting trees, it's fun!) they're going on 5 years of age... Truvativ Husslefelt's 31.08 in size....how much can a DH handle bar take? I'm asking from actual experience...I've heard after a couple of good impacts your bars should be replaced rather damage shows or not. Either way I have a new Easton DH monkey bar on the way...just curious if anyone has pushed it with DH bars after numerous impacts and ate poo due to failure.

    Ride it 'til it bends/cracks. Then, replace.

    I don't think my wallet could handle replacing handlebars given how frequently I lay it down... or into a tree.

    Carbon? Completely different.

    FIVE YEARS!?!? 2 years tops. maybe 3 if you don't ride a lot or too hard. Bars are cheap...faces are not.

    Yours is.

    But seriously, I agree, with frequent crashes 3 years absolute max.

    I've only had one bar fail on me and it wasn't a catastrophic break. If I had done one more drop that would have been completely different though. Always question why if things start feeling "weird"

    Ride em till they don't do what they're supposed to do. That's all you can really do tbh. Unless you don't like the geo after a while and want something different. Either way it's really your choice.

    I had my bars for about 20 months on my last bike (still looking for it )

    Yeah unless there are any serious gouges/dents in the metal, or they're bent at all, they should be fine. Carbon is a different story but in my opinion carbon and DH don't mix.

    i say if you slam them twice then replace them. if you haven't slamed them then replace every year, think about it if there damaged they wil probley break wile your doin that 15 foot drop or while your pumping around rocks going 30mph. in bolth situations you really dont want them to break and seriously anyone can spare $50 a year! what do you think is better spending $50 bucks or spending hundreds in the hospital?

    I like how people like to ignore the fact that like carbon, aluminum fails catastrophically.

    It also has a fatigue life, so replace your bars!

    Aluminum does not readily bend like steel geniuses.....it has shear planes and is not exactly "ductile".

    Every year to year-and-a-half for the bar/stem on the DH bike. Watching a stem shear is uuuuugly....

    I know, Al and Carbon fail in the same manner. Some of you peeps need to get yourselves educated.

    Another vote to replace the bars.
    Bike good, work bad.

    Good on you for replacing it. I replace mine every 18 months or so. Sometimes more often depending on the amount of abuse it's taken.

    I broke a bar a few years ago and survived. It sheared at the edge of the stem on the right side when I dropped off a curb. That small drop must have created just enough force to see a long-building crack finally go right through. I managed to not hit the ground and I was traveling slowly enough that I was able to stop safely. I'm just glad it's wasn't on a 10'er or a high-speed gap in the bike park. You can never know how much fatigue your gear is suffering from or how many little cracks are on the verge of going catastrophic.

    New bars are pretty cheap compared to replacing your teeth or months in hospital. Bars and helmets should be replaced long before you perceive a need for it.

    Wow, what a great response!!! As I stated I already have ordered a new bar... I was just curious on really the effects of DH AL. bars going south after too much abuse, or just failure during a ride after years of service. Mine were over extended, but I am not doing DH courses, just local DH trails that unfortunatly see spandex from time to time, so therefore definatly does not make that a true DH course! hahaha!

    Ideally, you shouldn't be on anything with cracks in them.
