I have a 2005 Trek 7200FX, purchased and have been riding it since 2006. I think I have a problem with the headset. A little backstory, I rode it in the 2009 NYC 5 boro bike tour, and it was a really, really rainy ride. Afterwards when I got home, I decided to tune up the bike a little, did some somewhat basic maintenance, cleaned and lubed the chain, repacked and regreased the hubs, and then I tried to do the headset/fork/steerer tube. I saw that some liquid rust was coming out of the seams between the bottom cup? and the fork. I took it apart, cleaned it up and checked it out. I'm not sure what everything is called in there, but one of the bushings? bearings? was cracked and was heavily corroded. I figured I'd just clean it up, grease it up, put it all back together and worry about it later. After that incident I've noticed some play in my handlebar/steering. If I hold the brakes at a stop I can move the bike back and forth a bit, and I see a bit of movement forward/backward movement between the bottom of the headset and the fork. I'm pretty sure at this point I need to replace something http://www.bikeforums.net/images/smilies/smile.gif
So my questions are:
1) I would like to know what size headset I would need to replace it
2) Is it hard? Would I be able to do it on my own? I think I have some basic mechanical skills, been able to do maintenance on my hubs, and biggest bicycle related project was conversion of my handlebar from flat to drops.
3) Do I need any special tools to put in a new headset? Starnut?
4) What part/brand would you recommend? I prefer something cheap and durable. Weight and fancy materials is not an issue.
Oh Yea, didn't post this in the Mech forum because I have no idea what parts I needed, figure i'd get some stuff Identified first.
