Hello,

I just purchased a Gary Fisher '02 Tassajara today, I'm a newbie so I tried to check the bike for obvious damage (cracks, dings, gouges, etc...) Everything looked OK to my untrained eye (couple of rub marks and a ding on the crank though). This bike was already assembled, I bought it right of the LBS rack. I had them put a pair of Continental slick tires and a Serfas gel saddle on and took it home. When I arrived home, I took a closer look (wiping the dirt and grime off) and noticed a straight vertical crack about one (1) inch long on one of the shock cylinders (Manitou Elite). There was also a green fluid oozing out of it. So, is this a manufacturers warranty issue or should I take it back to the shop?

Thanks!
