Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Wanting to build a single speed out of this bike...

Any advise from experienced people. I wanted to turn this bike into single speed, I don't think fixed is an option as the drop outs are verticle. Also thinking of just throwing on a pair of bullhorns, it would probably look interesting with the lines of this frame.

Any opinions?

You could use a White Industries eccentric hub and make it fixed. Otherwise, you could just space out a single cog on the hub.

I think it would look nice with moustache bars.

I guess the most important questions is - Do you have a budget?

You ok? Don't you guys realize that these magic gears are just that. Magic. Go ahead. Try every little trick that you can for using vertical dropouts and converting to fixed. If you get lucky then, yes. Magic! And voila. You will have fixed. Unfortunately, that happens far less often than you think. The formulas can't take into account many other variables that have an effect on whether you will get good chain tension or not. Many times this magic gear does not exist without having to make some doodoo adjustments like filing axles and stuff to get it to work.

Take of the cassette, put on a cassette cog and spacers, tensioner, blah blah blah. Sheldon Brown has all you need, and if not that, check this.

Just cut the shifter cables.
SS in five, at no cost to you.

Enjoy

I'm with Jersey. I like the shortening chain, and removing the derailer. It looks hardcore.

More like tardcore!

..but seriously, I went this way on my first completely botched SS "contusion", and it wasn't so slick. Especially when the chain ghost-shifted up to a higher cog and the chain tension went up so fast it bent my wonderful pot metal Alivio chainring into a taco.

..and after I banged that back into position, I realized the bearings in my rear hub had also been savaged. The whole wheel would move around from left to right (and up and down) on the axle, even though the quick release was tight. That was a bit disconcerting.

Anyhow, +1 on the freewheel cog w/spacers thing.

I just thought it would give him a chance to try out a SS setup with out commiting to it.Thats how my bike is set up right now (minus all derailers and cables) and been flying along for 6 months now. I've seen a bunch of bikes like that around...

I think i'll have to just run this as a single speed not fixed and probably stick on a singulator. Any thoughts on this? Thanks all for the advise as well.

Oh and I've found that I'll have rig the brake lever if I run bull horns due to the style of breaks this bike uses... requires more lever pull. argh.

singulators are junk. just use the old derailluer as a tensioner... the spring is more than likely stronger and if you a run a short piece of brake cable through it with the cable stop at the barrel adjuster, you can adjust it for good chainline. i'd also recommend picking up a shimano dx splined bmx cog. the ramped teeth from the existing cassette will make it prone to dumping the chain.

i'm with sin-a-matic with the moustache bar idea.

You can use travel agent adaptor to make road levers work with V-brakes.

Sweet! I that's what I was looking for... a way to modify my existing breaks. Now if I can figure a cheap way around the singulator I'd be the most happy. The whole point of a single speed to me is to get way from having the "extra" mechanical stuff on the bike.

20 dollars from nashbar gets you a 14, 15, and 16 tooth casette cog and wide assortment of spacers, AND a generic "singulator" chain tensioner. By and large the least expensive and easiest way to get everything on one shot.

Yes, just a gold color stock paint from specialized.

i'm eventually going to replace my dropouts with horizontal ones and run a multispeed hub.

here's another option, from fgg:

Oh hell yeah, that looks fantastic! I'm just now starting to rip into the bike and at this point I'm into the easy part... tear down. I've been messing around with the gearing to find what will work but my choices are so limited that I've decided to throw on a singulator for a bit.

Once I commit i found a frame builder who is more than willing rework the back triangle with track bike drop outs so I can run this fixed or ss.

Here we go... I'll have pics when it's at least part way finished.
