Hey folks, I bought this bike new in the early 2000's...don't remember exactly. It was handed down twice to family and is now coming back to me. As I understand, it has essentially been stored inside all these years and really not ridden at all. I am planning on a complete overhaul, simply based on age, so with that said, are there any proprietary parts that will be difficult to source given the age of the bike? I was thinking seals for the front fork and rear shock, and things like that.

Thanks,

Ultra
