After a seven year break I'm back into mountain biking. I went to the dark side during that 7 years and was a full time dirtbiker. But a torn ACL, surgery, and alot of physio has shown me I need to get back on the mountain bike.
Wow, I'm so amazed at how mountain bikes have changed. Full suspension was starting to take off when I quite, but I was so turned off with these bikes after my GT RTS-2. But it seems like manufacturers have really done their homework and come up with great bushings and linkage systems. I'm really impressed. Part of the reason I got out of mountain biking was my old Kula just didn't handle the downhilling very well. I'm a true XC guy, but downhills is 50% of the ride. So now that I'm getting back into it, I figure getting a different bike is good. So I find out there is a new category called "all mountain". Cool. Heavy for XC climbing, but smooth for XC downhills. So I find a cheap one in the bargain finder. A 2001 Giant XTC AC2. Nice bike. But like everything I own, needs to be overhauled to perform at 110%.
My time with dirtbikes has taught me alot about suspension. So I figure the first thing would be the rear shock. Surely the previous owner never changed the oil. Well I was right. But the funny thing is I'm trying to find out info on shock oil changes and nothing seems to be out there. Does nobody change their oil on their shocks??? I don't get it. My shock is a DNM backdraft air/oil shock. Seems like a pretty crappy one, but good enough for my comeback. But I can't find any info on this shock. DNM has been absolutetly no help. They suggested I send it back to Tiawan for repair. I don't think so. The shipping would cost more then the shock is worth. So I find myself figuring it out on my own. I just wanted to ask if anyone here has had experience with this shock and knows where I could get a seal kit for it. I'm also trying to find out the correct oil volume it needs.
Also, why are most of the XC bikes using air/oil and not a coil over shock? I would think a coil would be far better then air.
Anyway, thanks for your feedback.
