Want to replace headset on my 5900 Superlight . Looks like the bottom cup is bigger than the top. Does anybody make a replace set like Chris King, FSA etc. Or am I stuck just replacing the top only?Thanks

I assume you mean 2001 (as ridden in the 2000 tour) there was no 2000 edition of the 5900.. although it was technically released in late 2000..

Anyway, any 1-1/8 upper will work. A lot of people immediately dump the Cane Creek S6 for a Chris King upper. For the lower, you have to go thru Trek (talk to you LBS) they will replace it. I haven't had an issue with it. It is a special part made to match that fork which is used on the 5900 an the top of the line Kleins.

The lower cup is bonded to the frame, so the frame will have to back to Trek. Do not let an inexperienced monkey-wrench try to remove this cup.

Lower bearing assembly seized up after a few thousand miles on my 2k1 5900. As I understand it, Trek used a modified XTR lower assembly to accommodate the 1 3/8" diameter at the bottom of the tapered steerer. The LBS had a problem with the replacement of the lower assembly and rather than screw it up, they sent it back to Wisconsin. This provided Trek with the opportunity to lose the fork.. In the end, Trek found, repaired and returned the fork and the LBS made it all better no charge.

For what is supposed to be their top-o-the line ride, Trek built it up with a rather mediocre collection of components (Dura-Ace excluded). While the frame is a wonderful ride, there were enough problems with the peripherals that it never endeared itself to me.. I upgraded the problem-plagued pig-iron and sold it.
