>>1193450Bought this 1998 GT Outpost today and took it to the bike park. It was fun, maybe not as capable at harder stuff as my hardtail but a great bike. It got really muddy and there is a gritty feeling in the headset. Is it absolutely necessary that I clean out the bearings to prevent damage or is it not a big deal? On my other bikes I mostly ignored it apart from trying to spray in grease from the outside.
