I have a 2008 55 ATA2.
It failed in Morzine with the bottm three inches of travel not being available and the wind-down winding down while riding so I was ending up at the bottom with about 1" of travel all told.
They went back and had all the gubbins replaced.
Then early 2009 on a very cold night, I came out of the pub after a night ride to find only about 45mm of stanchions showing.
They went back and had all the gubbins replaced with 2009 gubbins.
Then a few weeks ago, after a cold night, I went to get the bike out of the garage and found only about 45mm of stanchions showing.
They went back and had all the gubbins replaced.
When they work I really like them. I've got about another 13months left on the warranty and I'm fully expecting them to go again at some point during that time. If they do, I'll have them fixed again and ride them 'til they die. I couldn't sell them on with a clear conscience.
Having said that I understand the 2010 versions to eb so comlpetely different inside that you can't base any judgements on them on what's happened to the 2008/9 forks. Sadly for me they don't do any travel adjust ones any more or I'd replace mine. Maybe, just maybe, they'll re-introduce a problem-free adjustable travel one in the 2011 range?
