Can I replace Cane-creek headset on 2001 Trek 5900 with CK?(6 posts)

Can I replace Cane-creek headset on 2001 Trek 5900 with CK?PwAg

Recently went down to my LBS to get my Cane-creeking headset replaced with a Chris King 1.125" headset (have one on all my bikes). But when the mechanic slipped off the fork, he said it was a no go...steer tube had a special warp to it so he deemed the headset was built into frame for good...ack. Is this true, or is the guy a bit mis-informed like myself? I just have not had the time to pop it open and give it a whirl...too many rides lately :) I did go into the shop late at night, so maybe he was in a rush and wanted me out.

It's a Trek 5900 USPS 2001 62cm Superlight. LMK if any of you have had similar problems. Thanks.

Could be that the ID is such that he can't get the headset remover to hook under the lip of the HS. In reality this stuff should be pretty straight forward and there isn't much reason to make things too difficult, but recently it seems that several mfr.s of frames don't think you should be able to get a HS out once it's been installed. A decent wrench should be able to get the "Can Creak" HS out and King should fit. Your biggest issue should be stack height and facing, but as long as you have some spacers in there now you should be OK. Maybe drop the bike at the LBS so they have some time and/or find another wrench.

Sorry, but you cannot. Trek is using a special fork (actually a Klein fork design) which has an over-oversized steerer tube at the bottom (1-3/8" I believe), which then is reduced conically to 1-1/8" at the top. At best, you could replace the top cup, bearing and cap with the Chris King, but for now you are stuck with the lowers.

Do you think it would be worth it to just replace top cap and bearing with CK? I just get the chills everytime I think about my buddies cane creek dripping rust after a few rain rides. BTW, this is not my bike...loaning it from friend...maybe I should just let it be.

I'm not sure which Cane Creek top is used, it is either the C2 or S5 model. Anyway, I would pull the fork out, clean everything up, and then re-assemble with a heavy coating of quality grease on the bearings and races. Even if the bearings are "sealed", cover it all in grease to help avoid water contamination.

Replacing with the CK upper would seem like a costly option. $100 and you are only using half of the parts! If you look at Cane Creek's website you can order parts from their store section. www.canecreek.com

Hmmm, maybe there is a good reason why it's so easy to order parts from them? Like, people need to do it a lot! ;-)

Best thing to do is to clean, grease and reassemble - especially if it's a loaner. Even that would be condsidered "returning it in better shape than you borrowed it."
