Just got off the phone with SOLA.
My wife's bike (Christmas present) has a 34 performance with new fit 4 damper and the rebound adjust has seized after a couple rides, the bike is basically brand new, not a scratch. From googling it seems a common problem with the indent ball.
Shop I bought it from has closed, it's a Liv so called a Giant dealer who want $150 to send it off, fair enough I didn't buy it from them and no one wants to work for free but it's a new bike!
Called Giant in Melbourne but they didn't want to know about it stating it's a Fox issue.
Called SOLA and explained situation said I'm happy to take out the 5 bolts and remove the fork, they had a bike shop call me back 2 minutes later who will handle it for me I just need to drop it off with proof of purchase.
So far so good, will report back soon.
