I have a 95 Trek 7000 and was wondering if I could put on a 1 1/8" threadless suspension fork? Right now the bike has on it a ridged Cro-Mo fork with a 1 1/8" threaded quill stem. I know it may not be worth the money, but I really like the bike and plan on keeping it. The bike is in almost new condition or I would not bother.........

Yes, a suspension fork can be fitted to the 7000. I believe that there was a 7000SHX available that year that used the same frame but included a suspension fork. You will need a new stem and threadless headset along with a suspension fork that has cantilever brake posts. It would probably be best to use a fork that has around 80mm of travel. I have a 1993 Trek 7000 that I installed a suspension fork on around 1995 and then replaced the fork with a new Rock Shox Recon Race last year. My 7000 originally came with a threadless steerer, but it is no problem to change from threaded to threadless. The newer forks are slightly longer that what this frame was designed for, but this only slightly relaxes the steering geometry and I find that the bike handles very well. My fork has adjustable travel and I do have it set at its minimum (80mm).

Am I right in seeing a front cantilever brake? This will be difficult to adapt to a suspension fork due to the need to anchor the cable on the fork itself. I would switch to a v-brake at the front.

That looks in almost showroom condition. For adding suspension, yes, why not; but you will need a few other bits on top of the fork, unfortunaly it's not like the past where you could buy a fork with a threaded steerer tube and fit.

Would suggest looking for a short travel fork, 80mm-100mm max, as this bike would not have been designed for the length forks mainly avaliable now whcih are 100mm+, say something like a Marzocchi Marathon LR or Rock Shox Recon.

Would suggest looking at the lower end of the market, but not budget. You do get what you pay for, but most high end forks are 140mm+ or if short travel very expensive like Rock Shox SIDS

Also, you will have to get a threadless headset, as you can not get any decent fork with out this now. This will also need a new stem, would look for a shorter one to you currently have (90-100m), this will improve the handling of the bike. Most forks now are also disc only, if you are planning to keep the bike long term, going disc for the front is a worth while upgrade, this would also need a new wheel

If looking for 2nd hand forks, be careful as the cost of servicing and finding spares will soon add up, and come close to the same as a current lower end fork, and you will still have the issues of the headset, and discs.
