Hey guys, I bought a Mongoose Rockadile Al a few years ago back in 06 (pic attached), I rode it around the block a few times and took it on holiday etc but never really got into Mtb. Recently a mate of mine was looking for a bike and it sparked my interest in the sport again. I've also been looking at a few mid range bikes as I know mine is pretty much entry level. Would it be worth to upgrade? or try sell it and get another one, how much would I get for it? I was thinking of disc brakes for starters, dunno what else to look at/do, I remember my suspension was very bouncy
