I've used my new monocog 29er religiously for just over a month and have put countless hours and miles on her. The things I've changed so far are the seat, grips, pedals, brakes and tires. Riding some local singletrak last night and I hear some creaking form my headset. I'm wondering if I should pull it apart and check it out or just tighten in up a bit. Not sure if they have sealed bearings in the stock headset or is it possible to grease? Same for the stock BB I guess, should I pull apart to check out or? I use the bike hard but I'm pretty anal about cleanliness. I hose the thing down after most every ride and then wipe it down and clean/lube the chain. I know water is not great under pressure but I'll just do the necessary maintenance to keep it dialed in. Any suggestions?
