I am a road biker for the most part. I also have a beater mountain
bike that i use for local chores. I do not off road mountain bike.
The Mountain bike is at a point where i have to do some parts
replacement.

The front chainrings are completely chewed up and need to be replaced
along with the cranks and chain. I only have the 2 bikes (road and
mountain). When i replace the chainrings, I am considering either
making the bike as is with 3 chainrings in the front or removing all
of the clutter and having a fixed gear bicycle. Please only make
comments if you have experience with both styles of bicycle (mountain
and singlespeed) or let me know if you do not have any experience with
one style of bike. Any input would be appreciated.

I don't post here a lot, but i am a frequent reader. I really
appreciate the comments of some of the frequently posting people on
many of the other topics posted, and I wanted to say thanks to you
for helping all of the other visitors who are not as knowledgeable on
the subject as yourself. The input does go much farther than you
think.

Thanks Matt Brink
