Niner Carbon Fork Still Rideable After Being Smashed With Hammer

niner-carbon-fork-hammered

You may recall the video where Niner Bikes co-founder Chris Sugai smashed their new carbon fork with a hammer. A few people posted comments about what the inside of the fork may look like, and Niner said that while it was structurally sound, it should be replaced if such damage occured. The point of the test was to show that even massive hits to the fork wouldn’t result in catastrophic, rider-flying-off-a-cliff, certain death failure. Well, it seems Niner wanted to see if the fork was rideable afterall, so they tested it. Here’s the results:

After abusing a carbon Niner fork with a ball peen hammer, we sent the very same component off to our testing facility and sent it through the same rigorous tests that our brand new forks undergo.

Niner forks are tested to the new European standards specifically designed for mountain bike use. To pass these safety standards the fork must undergo a load of 650 Newtons, both pushing and pulling on the dropouts for one hundred thousand cycles. Our hammer fork passed this test easily, so we kept going… and we upped the load. At 750 Newtons, the hammer fork passed another hundred thousand cycles, so we kept at it… and at it… In the end we were not able to get this fork to break until after three hundred thousand cycles! The Niner carbon fork tripled the most stringent bike product safety standard out there, after being beaten with a hammer! We would prefer that you didn’t do this to your fork, but it is nice to know how tough these things really are.

Also, they’ve updated their demo shop list, so if you’re looking for a local shop that has demo bikes in stock, hit ‘more’ to see the current list.  Oh, and you’ll see their sweet Niner Sigg water bottle…

These bottles are tough, reusable and just look damn cool. Made of aluminum (with Sigg’s new BPA-free EcoCare liner), they will resist any beverage you put into them and last for years. Sigg manufactures to high ecological standards and is 100% recycleable.  We grabbed one from Interbike (thanks, Chris!!!) and they’re pretty sweet.

I think this test would have been much better if they had beaten a fork that had a hub in the dropouts. Without that bracing effect, the fork leg will flex and vibrate when you hit it with a hammer. If there was a hub in the dropouts, then the hammer would have more leverage and the test would better simulate a crash.
Still, it’s a pretty cool test video and I’m amazed that the all-carbon forks could withstand such abuse, brand-new or not.

Following the testing press-release, a second press release was issued announcing the new 100gram lighter fork for 2010 :) ….

Is there a typo here? Three hundred thousand cycles, very impressive.
750 Newtons? It this correct? Isn’t that 15 lbs? I’m not impressed with 15 pounds of pulling force, even for a million cycles. Can anyone clarify?

Steve - 11/24/09 - 10:18am

Actually, the correct conversion from Newtons to lbs is 750 Newtons = 168 lbs. The fork is in a test jig that simulates a fixed head tube with a standard headset installed and the drop outs are pushed AND pulled with this amount of force for that many cycles. I hope this helps.

Steve, thanks for the clarification…always nice to get it straight from the source.

Thanks Steve for the help there. My apologizes to all.

Paul, it actually did have a hub installed during the hummer test. watch the video.
