Questins about headsets
I searched this forum like a good little newb but couldn't find the answer I'm looking for. Can somebody explain to me the difference between a threaded headset and a non threaded one and are the two interchangable? The reason I ask is because I have a Trek 7200 with what I assume a threaded headset and like the look of the higher end trek ones better which I assume are threadless. Can I upgrade to a threadless one?

Park Tools' web site (www.perktool.com) has a very good explanation of the entire spectrum of headset types. It's much better than trying to type a necessarily long description here.

Threadless: https://parktool.com/repair/readhowto.asp?id=65
Threaded: https://parktool.com/repair/readhowto.asp?id=127
Bikes don't care if they have a threaded or threadless headset, so long as you have the correct stem, headset, and fork, and the bike's head tube is the correct size (usually 1&1/8' or 1'). Size will be the most important factor in finding a new headset.

"Threadless" headsets are almost universally applied to mountain bikes, and increasingly to current roadsters. They are simple to adjust, very strong, and stay in adjustment.
"Threaded" headsets are often seen on older MTBs, and large numbers of roadsters. The stem used on these is the "quill" style, which inserts into the steering tube and is held there by a wedge/screw arrangement. Adjustments are made by means of a threaded bearing cup and a lockring; an arrangement that occasionally causes headaches. The wedge frequently siezes inside the steering tube, causing no end of problems.
Many roadies like the clean looks of the old-style stems, which can be very swoopy. The threadless (or Aheadset) style tends to look clunky and mechanical, with lots of securing bolts and all.

^^^....Parts being fork,HS and stem. There is also no good reason to change to threadless unless you are already in the market for a new fork.
