Newbie-headset conversion question(4 posts)

Newbie-headset conversion questionRemmingtonShowdown
Jul 14, 2003 7:24 PM
So here's the story- I bought a great Trek 5500 with all the bells and whistles yet it has a traditional threaded headset with a Cinelli Frog quill stem. I was considering converting to a threadless setup so I can buy a stiffer fork and save some weight. I am maintenance savy yet am in the dark whein it comes to this. If anybody had done this, seen it done or can tell me what sort of mess I am getting myself into I would much appreciate it. thanks!!

... did I see this topic posted once before?

While your swap is debatable... the only caveat might be the headset used on your 5500.

I'm not completely Trek savy... but know that on some high end contemporary models (along with Klein) that they use differently sized upper and lower bearings (I've got a Klein Q Pro Carbon which uses an oversized lower bearing and no fork crown race). You'd need to determine and locate the proper headset for the job (bought my Klein as a bare frame/fork... got the headset from a Trek dealer (who, ironically, originally sold me a straight Cane Creek IS before finding the right parts)). The above Park link has all other relavent info (remember, measure your steerer three times... cut once). With the proper tools and parts... it's fairly straighforward.

Be the bike.

Here we go again...

There is absolutley NO good reason to switch to threadless, except perhaps that you have a wheelbarrow full of cash that you don't know what to do with.

What fork would you get that would be "stiffer" then what you have ?. "Stiffer" in what way ?, laterally ?, less compliance ? , and why wouldn't you want that ?.

Perhaps if you go into further detail as to what you are trying to accomplish with a new fork and why you don't like the existing, then maybe we'll have some useful advice.
