This is a Mountain bike that built up about 15 years ago. Its a early Specialized FSR M4. The FSR was first introduced in the late 90's. When I built this bike, I planned that it was going to be the last bike I ever built. (That did not work out the way I planned), as a result I ended up splurging a little bit on the budget for this one. I originally built it up to be my dream bike. I have two set of wheels for it, the others are Red Mavic 517's. The mags just looked cooler, and I used them on crushed gravel paths. It currently has a SRAM 9.0SL drive train, Paul Breaks, a Race Face Crank, Tioga Spider Pedals which were swapped out with Titanium Time's when racing or riding off road, Chris King Headset, Thomson Seat post, (Some Aluminum Housing German Cabling System that I forget the name off), and a bunch of other time period goodies that were available online back in the early 2000's. (Basically all the stuff I always wanted, but couldn't afford until after I got set in a decent job). I last rode it about 2 years ago (it needs a new chain, last time it was used I went mountain biking with a friend who is a Clydesdale, and I let him use this bike, he snapped my chain so many times I decided to just throw it out). Just looking at it today, it's bringing back some memories. I'm going to have to get this one back out on the trail this summer. If I remember correctly, I seem to remember reading articles in the early 2000's that stated this was one of the first full suspension race bikes that out performed hard-tails at the races. (I don't know if that's true or not, but people were talking about that type of stuff when this bike first hit the market). Magazines like MBR and Mountain Bike Action were raving about this bikes capabilities. I never put a whole lot of miles on this bike, as I found my older steel Trek 930 just as enjoyable to ride, and the Trek was usually the first bike I grabbed when I went out for a ride. I'm sorry for the incorrect title, My PC crashed while I was making this post, Then when it booted backup the tab was restored, I accidentally hit enter, and the post was saved before I entered all the information.. It seems I'm unable to edit the title of this post.
