Old bike upgrades / repairs
New member here and new cycling enthusiast. I'm saving up to get a road bike in the next few months (wife won't let me buy it right now because I already spent alot this year on a mac and some other toys). So in the mean time, I decided to start riding my current mountain bike. Its an old bike probably 6 years old. I don't even remember where I bought it but it has the stickers "MGX" on it LOL. Anyway, the bike is still in good condition. However, I think the front forks/shocks are shot. Are they pretty universal where I can buy new fork/shocks and just replace the old one? I wanted to change the front rim and install quick release too so I can mount it on the truck but apparently I have to buy a new rim because the hubs are ancient.
Thanks for any assistance. I'm rather embarrrased to take it to a bike shop so I'd rather do the upgrades/repairs myself.
