Can anyone identify this Gary Fisher or give me an approximate year? The serial number is FS90071877. I dont know anything about it other than it is a ChroMo frame and has Shimano 400 components. I am a truck driver and wanted a more compact frame to carry in the truck but I also wanted a SS. I know absolutely nothing about MBs but I got this in hopes of dooing an inexpensive conversion to SS. I would really love to have a disc brake also, front or rear or both, dont really care. Any suggestions on the least expensive and still effective way to get this bike to SS/Disc Brake? Tod

1990 or 1991.

Disc brake conversions require new hubs, a compatible frame/fork, and the brakes themselves. It can be done on a bike that old, but would cost more than it's worth.

thanks! how about forks?
 

I appreciate the reply and certainly the info on the bike and the conversion. I don't know anything about mountain bikes but I am somewhat versed in road bikes. I do understand spending any real money on this bike would require shelling out more than it is worth but "worth" is a relative term.. LOL I like the bike, it suits the purpose and I prefer older stuff. It just isn't "quite right". I have nothing in the bike at this time, here is my question.. The bike has a Gary Fisher Evolution headset and fork, would it be possible for me to change the front fork and wheel/hub to a used one with disc and if so what should I look for? Does it have to be a specific fork size etc? Does not need to be severe duty as it will only be ridden on the street and occasional dirt road. Thanks again for the reply, Tod

To do a total conversion to disk is not worth the money on a older bike. It's best to work with the current brake set up and put better brake pads on

To do a convert over to disk would range in the $$$ range if you're not doing your own work.

Here's two new bikes with disk brakes and one with dual suspension and one with front:
$300

$350

But really, don't put too much into a older mountain bike. They are not like road bikes which increase in value by how much you add on to them. An older mountain bike is a OLDER mountain bike, there is no money in upgrading them and they are not worth the money.

The guide to SS the bike.

Shopping list:
3/16 chain, just a cheap one
one ring taperred crank bolts
Bmx freehweel
Chain tensioner for 3/16 chain

What teeth count do I want for my freewheel?
Well consider what you're riding over:
Flat land/roads?
Hills/off road?
Mountain/downhill?

Do me a favor and count the teeth on the crank and give me an order like: 32/46/54
And then tell me what you want to use the bike for.

The # of teeth maybe labeled, mine are on the inside facing the frame

Evolution is a 1 1/4" steerer tube, so you'd need some head tube shims and a new threadless headset as well as a 1 1/8" fork with disc mounts. Add a threadless stem in the mix as well. If you wanted to keep the original front brake lever, you will need a BB7 road disc caliper, as well as a new front wheel.

All of this could easily cost you over $300 in parts alone even if you shop around for deals.

I didn't know the figures but I was spot on.

So it'll be cheaper getting a new bike in the long run.

getting closer thanks to everyones help... gear rstio? steerer tube?
 

First of all thanks for all the valuable info. I had looked at the bikes suggested but after sinking a ton of money into my bike that was recently stolen I just can't fork out another 300 or so which is why I am trying to at least get close with this Fisher frame. I got lucky and bought a badly damaged bike at a coop for $25. The frame is shot buit the forks are perfect, they have disc brakes, and the wheeelset is decent. I will be doing the work myself, hopefully this weekend, so I need help with a couple things. I have a chain and a tensioner also so I think all I need is the shims to make the 1 1/8 fork fit my 1 1/4 Gary Fisher frame, tell me if I am reading that reply wrong please, and the parts necessary to go single on the rear wheel. The front chaining is currently 48/38/22.... I will be riding mostly flat ground, primarily roads, an occasional trip along dirt roads and mild trails to the fishing holes with my son. Very few hills, no real off road. I need help with gear selection for the rear and what type of freewheel to look for. Thanks in advance, y'all have been a big help. Tod
