Clydesdales/Athenas (200+ lb / 91+ kg) - Should I change a suspension fork on a hybrid

My wife has a Trek 7200. These bikes have suspension forks and seat posts.
We both mainly ride our Specialized Sequoia's. The 7200 is for leisure putting around, looking at the sights etc. We do not do trails - only pavement.

So I have been thinking about changing the front fork to non suspension. I have already changed the seat post.

My questions:

1. Yes / No good idea or waste of money for getting a little benefit (less weight etc).
2. Easy to do - do it myself or being a noob at bike repair let my LBS do this.
3. Reasonable price to do this or expensive. (Not interested in expensive replacement fork).

Thanks

IMO if you are just putting around not putting many miles on the bike leave it. There are to many expensive things in this hobby to waste money on a bike you are not gonna ride extensively. Also it gives you the option of doing some light trail stuff if you ever find it neccessary.

When I swapped out the suspension fork on my Giant Sedona DX it was because it was my only bike. It made a difference to me mostly for handling, the weight was pretty much irrelevant.

I enjoy the ride more, and would gladly do it again, but I was putting a lot of miles on it.

If I was only putting on minimal miles, I probably wouldn't bother.

But, if you do, there are a couple of issues to consider. Removing, and installing the crown race on the fork. And also, installing the star nut in the fork, and potentially cutting the steerer that are specialized enough you may want to consider paying the LBS a few bucks to do the job. It isn't too complex, but I went ahead and paid to have it done, just to avoid the headache... I switched from a threaded to a threadless headset at the same time, so there was a little more involved in my case.

Agree with jesspal: if you're not riding the bike much, why put money into it? That said, it should be pretty cheap. Rigid forks run $40-100, with some pretty decent (if heavy) chro-moly models available for $60-70. Just make sure the axle to crown race distance is similar between the old fork and the new fork! If you buy a fork that is too short, the handling with be unridably squirrely. DAMHIKT...

Install is easy, but does require some specialized tools. If you don't own the necessary tools, it's probably cheaper to pay your LBS to do the install. I think my local Performance Bike charged me around $30 the first time I needed it done. Ideally, if you were going to do it yourself you'd want the following tools: a star nut setter ($10), a crown race remover ($20), a crown race setter ($30), a steerer tube cutting guide ($13), and a hacksaw. All of the prices are for generic Nashbar tools, BTW. I own several of these and they're perfect for a home mechanic.

If you don't want to spend money on tools, there are alternatives. Many people use a piece of pipe rather than a crown race setting tool. The steerer tube typically doesn't have to be an extremely precise cut, so many people do it freehand. Rather than buying a crown race remover, I typically buy a new crown race ($5) or pay my LBS to remove the old one ($8).

Thanks guys! I think I needed the "voice of reason" to curb my impulses.

I think the voice of reason is a wise choice. I had contemplated doing the same to my 7100, but realized the expense didn't warrant my non-active use of the bike. I ride my road bike 90% of the time, my MTB 5%, and the 7100 5%.
