The frameskin arrived today for my Giant Trance X2, I took a gamble and bought the 'skin' for the 2011 bike. My Trance is the 2013 model, but I've been told that the frame is basically the same. Only time will tell!
The film itself is Avery automotive film, checking their website for information shows that it's got a 7 year guarantee. So it should resist yellowing and cracking, which was a concern. There's also a video on the site with instructions on fitting the film. I'll post some photo's if the installation goes well.
