Well I've been interested in SS/Fixies since I've been riding, but never brought myself to spend the money on buying one since I'm still a big fan of my gears :-).. BUT, I've got an old Fuji M100 hanging in my garage that is/was my grandpa's and it's pretty much been wasting away for the past 4-5 years.. I've been wanting to revive it, but can't bring myself to spend the money to make it just a fuji m100 again bc, incase you don't know. the bike really isn't worth anything considering the M100 was the box store fuji mountain bike...
So anyway I've decided I'm gonna turn it into an SS/Fixie.. I'm going SS but want to do the flip flop hub..Now I know little to nothing about SS and just a little more about bike mechanics in general.. Though I can usualy figure stuff out :-). I do have a few questions,
1. Is it a decent idea to put 700c wheels on a bike set up for 26'' or am I asking for trouble?

2. Gear ratio? where do I begin?

3.How do I know what cranks will work with my frame?

thanks, lol and wish me luck!!

1. its OK but it wont be a direct replacement you will need new brakes.
2. experiment with your geared bike.
3. you can keep the crank thats on it. Remove the smaller chain wheels and work with the largest.
4. Bikes with rear horizontal drop outs work best for single speed bikes. Geared bikes generaly do not have them.
5. I would just buy one. In the long run it will be cheaper. But if you are looking to build a kick ass top of the line fixie building is the way to go. Just be aware its not cheap if you need to buy all the components.

Yeah i know its not my cheapest route.. More of sentimental with this bike... But im also not looking to build this bike n a month

I had to swap out my BB for a really narrow one, and move the chainring inboard of the spider to get a good chainline on my Raleigh.

Here are my thoughts. Instead of swapping for 700c wheels and tires, you might be able to get away with swapping tires and tubes for skinny 26" road tires. For a couple of years I ran Forté Fast City K 26x1.25 tires on my geared MTN bike, and they were great, they really transformed the ride! I think their replacement model is the Metro K. Don't forget that you'll need matching tubes if you go that route. Doing that will save you from having to buy rims and brakes in addition to tires and tubes. Just remove the derailleurs, shifters, rear cassette and install a single cog and some spacers on the rear wheel. If the frame has horizontal dropouts, that's great, just swap the chain for a single-speed unit (SRAM PC-1 works well), otherwise you'll need some sort of chain tensioner, like a Surly Singulator. Performance Bike also has a kit including the spacers and the tensioner. It might be worth investigating. The nice thing about using a cog and spacers is that you'll have some flexibility in adjusting the chain line to your liking, the downside is that it's not a flip-flop setup, just single-speed.
