so last time i posted i was buying a cannonadale frame will the person sold it and forgot to tell me ******* lol but anyways i have that gt moutian bike just sitting there the front brake dosent work and the gears i was wondering can i make it ss/fixed bike i need road bike wheels and do i need a new fork ?

here is a pic of the bike

Alexrobots

do i need new cog or spacers since im taking of the gear thingy

Alexrobots

here the build as it looks now i took the tires seat and seat post out i think i need new cranks cause i cant figure out how to get them of to make its fixed also i cant figure out how to get the brake lines off help me

i r yo

To be blunt - it's not worth it.

You'll need a new rear wheel, cog, chain, and probably a crank set.

All this on top of your frame having the wrong drop outs in the rear. In order to adjust chain tension you'll want horizontal drop outs instead of the vertical ones your frame has.

It's a pretty cool frame though. I'd vote for keeping it as a mountain bike.

Stop. Stop wrenching at your bike with blind wreckless abandon. Yes, it can be made into a fixed gear. You are going to need a new crank, new bottom bracket, a new rear hub/wheel, cog & lockring, chain tensioner and chain. I think I got everything.

But your going to need a singlespeed MTB crank with a matching bottom bracket that is the right size for your bike. You need a rear hub that can accept a cog and lockring. You need a chain to drive the whole thing and a tensioner to keep the chain tight.

Build cost: 100-300$

IMO it's not really worth making it into an SS/fixed gear due to the vertical dropouts. It is possible, but you either have to get lucky with the perfect gear or get a really expensive hub to make it work. You could run it SS with a chain tensioner though, but I think they look tacky.

You won't need a new fork, or anything else really unless you don't like the stock stuff. I suggest starting here: https://sheldonbrown.com/fixed.html

*Edit: I also vote for keeping it a regular mountain bike. It looks nice as-is.

Alexrobots

i still want to make it into a fixed gear i think it would be a fun rewarding experince

Capocaccia

Does your bank account smile with glee at this same fun rewarding experience?

for as much as you'll spend you could something like buy this:

Have you ever done this before? Do you have any knowledge of bikes whatsoever? You cant just take tools and start wrenching it before you have any idea of what you are doing. It will cost you way more and require a lot of bike knowledge to undertake what you are attempting to do than if you were to convert a roadie or just buy new.

Well, I got bored last night and looked up prices on all of this stuff. Lets just say I couldnt find a new SS MTB crank for under 150$ and could only find last years models for 100$. Its gonna be at least 250$ to get this ride going as a fixed gear. Basically, buy this instead. Its the same price as your build.

The kid's got pep, but it's not a good idea

Alexrobots

so everything is off the bike now im waiting on parts i found a crank online on ebay 40 bucks so we will see if it works and the guy at bike of america by me is going to keep a look out for some used parts

FastJake

I can't think of a nice way to say this, so I'll just say it: it is highly unlikely your GT will ever be fixed gear. Vertical dropouts are a HUGE road-block for an SS/FG project. Buying parts on ebay and "seeing if it works" is another red flag. You will end up spending lots of money on this bike and not get what you want out of it.

Sell what you have left and buy a bike with horizontal dropouts if you really want to undertake an SS/FG project.

Alexrobots

i do belive it has one dropout

I do believe it's a waste of time trying to help this one.

rustybrown

I'm all for the project. Want to see where this goes.

Magic gear ratio. It will help with the vertical dropout situation.

bumblebeetuna

Keep us updated. I suspect you will learn a lot with this project.

Alexrobots

So I have the crank on but what do I excatly need for the back side of the bike

Alexrobots

I will learn good and bad but what ever I will enjoy it

It's a pain in the a$$, but very doable. Here's mine:

I won't go into to much about it because last time I spoke up I got a ton of crap over it. But I run fixed with 46/16 as my "magic ratio".
Bottom bracket is stock, crank set, stem and bars from ebay, wheelset from a friend, brake and lever from LBS, cog from Amazon.
I say go for it, use it as a beater and get a "proper" bike later. It's a fun project and you'll learn a lot in the process.
Good luck and keep us posted!

coma061

Oh yeah, all said and mine cost $250 total.

honestly dude, i dont mean to be a jerk but it seems like you only have a faint idea of what you are doing. i could be totally wrong, but converting a mountain bike to a fixed gear bike is not exactly an easy thing to do even for people with experience building bikes.

especially with comments like "i do believe it has one dropout" and "taking off the gear thingy"

also, again i could be wrong, but a mountain bike to singlespeed conversion is not exactly cheap either.

then there is knowing about all the various dimensions/sizes/compatibilities/makes/models/etc of lots of different components on the bike and how they work together.....lots of stuff we cant just tell you.....not because we dont want to help, but because its sort of niche thing you are aiming for....

for instance, to have a fixed gear bike from a mountain bike frame without horizontal dropouts, you need what is called an excentric hub for the back wheel, and those run more than a hundred dollars. then you have to build the back wheel off that hub, which would mean learning how to build a wheel, which is not exactly an easy thing to just pick up.

i dunno, maybe im being too negative, its just i would sort of feel bad if you just kept buying random bike parts that dont fit your bike and you waste a couple hundred dollars and have nothing to show for it.....

illdthedj

i think thats pretty badass!

maybe i spoke too soon. alexrobots, you should bug this guy for your information lol

illdthedj

speaking of mountain bike to SS conversions.....check out these haro extremes! i love that fugly frame!
