Here Is about my 500th garage sale bicycle I've bought
over the many years...I convert em all to single speeds
I just anchor the cable stop In the barrel adjuster,take
the rear brake off...here It Is about three pics

dude, if the dropouts are long enough, take that derailleur off! THEN it will be hott.

What, no rear fender?

What, no rear brake?

rear brake's are for *****'s

...that looks like a girl's bike!!! haha..

I've found that the bicycles do better with a deraueller cause It acts as a chain tension
otherwise things can happen like loose bottom bracket from uneven forces If chain
gets to tight{what way Is the rear deralluer hurting anything the way It Is]

Thats what I say when I see Urban, DH and DJ bikes with inclined toptubes.

HEY, NICE GIRLS BIKE!

I have a frame like that in the garage, a Cambio Rino? If the owner gives it to me, it's gonna be a chopper.
Like with waaay too long forks. Already ran it with a 24 inch rear wheel. Easyrider.

Maybe nothing but it is another mechanical thing to break or whack and knock out of adjustment. It adds some drag, noise and weight which may or may not be important to you. Many might feel it is visually unappealing to have a singlespeed bike that looks like a multispeed. The fact is that there are alot of singlespeed conversions that have overcome the problems you mentioned. But ultimately these are your bikes to do with as you wish.

Chip, they make very nice chain tensioners? (sp), they are used on DH, DJ bikes.
Why not run single chainring mid front and use the rear derailler? 5-7 speeders?.

Something like this.

I hear what your saying I usually do on some run the rear dearalluer and run centre chain ring In front
especially If I'm trying to sell It but for myself I convert everything to single speed-just anchor the cable stop In barrel adjuster

There just cafe cruisers If anyone Is wondering racing bike NOT
It's just that I run Into so many of them at garage and yard sales
and I know that they would satisfy some poor fellow or gal for awhile?
