Niner Bikes co-founder Chris Sugai proves with a very awesome example that their new full carbon rigid 29er fork is as durable as you could ever want it to be.  Hit ‘more’ to see a still photo…
The fork on the left is their Reynolds steel rigid fork, and it looks a little worse for the wear.  If you didn’t watch the video, this damage was done intentionally with a 16oz hammer with a hub installed in the legs.  The carbon fork has only paint damage, they claim there are no structural failures (cracks or punctures), but they also said you probably wouldn’t want to ride this fork again if something similar happened trailside.  The point was to prove that it’ll take some serious abuse without catastrophic failure.
