It's for a flip flip hub...
Some people ride single on one side and fixed on the other. Or you can ride fixed on both sides just different sizes.
Magical right?

its so you can run a chain from the back wheel all the way to to a cog on your front wheel.
you're fixed on both wheels of your bike.
it sucks cause you can only bike in a straight line.
kind of fun.

something like that...HA
It was saying that if you have two chaing rings for example( 44 and 42) and buy the surly "double fixed cogs" u can just switch the chain without worrying about getting the right tension...
makes sense though, I just did not want any faulty products

"Surly Dingle Cogs are part of a different concept for fixed-gear drivetrains. Having two cogs on the back means you have more options for gear changes when the conditions demand it. For instance, say you want to ride your off-road fixie from your house to the trailhead, but your gear combo is either too high for the dirt or too low for the road. With a 17/19t Dingle on the back, pick two chainrings that are 2 teeth apart, like a 44t and a 42t. When you change from the outer (44:17t) gear combo to the inner (42:19t), you'll have a much better off-road gear and your wheel position will not change. This maintains effective chainstay length so you won't have to worry about having too much or too little chain length to accommodate the gear change. The Dingle (the word derives from from dual and single) works great in hilly terrain both on or off-road. Like our cassette and track cogs, these are made from machined, heattreated and chrome plated SCM415 CroMoly steel, so they are tough and long lasting. They're available in 3/32" (narrow chain) tooth width 17/19t, 17/20t or 17/21t combinations. We recommend using 9-speed chains only. You can thread it onto any standard ISO threaded (1.375x24tpi) fixed gear hub and it takes up the same 7.4mm threads as a standard fixie cog. We recommend using a wider lockring (like our improved track lockring) to assure you can get a lockring tool onto it."

I think its putting two cogs on one side of your hub
You can thread it onto any standard ISO threaded (1.375x24tpi) fixed gear hub and it takes up the same 7.4mm threads as a standard fixie cog.
So you have a choice.
It's basically like riding a two-speed except changing speeds is a bitch and cant be done mid-ride.
I have seen people ride hubs with two fixed cogs, one on each side, with two chains, the idea being if a chain breaks you have a back-up brake.
That would be a double fixie

why thank u mr. friction for your help. I would love to ride my bike in a straight line : |

FIXED on the SAME side of the wheel, you must use a skinny chain though, you are limited ot the sizes you can us enot just by sprocket and cogs, but dropout distance also

@PURP
hmmm sounds interesting... i think i just might purchase that surly then
so u mean peeps put two chains on one side???
pretti*ugli12.18.08 - 3:02 pm
reply
so final question would be
Good idea to have two cogs on the same side?
Or just keep the flip flop hub... The two cogs on the same side appears to be a little more easier to switch gears. But then again a quick release skewer would make it easier.

well thanks hipsters for all your helpz... My road to hipsterdom will be a fixed, tight pants, and skinny one...

Dont do quick release on a fixie hub, thats bad noose, no pun intended. I luv Surly but different side hubs are better cuz u can use 1/8 chain. Its possible to use one chain with two cogs, u just gotta be dialed. I did 48/14 with 48/18 as well as 48/18 with a 48/21
Just do 48/18 its the best ratio I ever found for all around brakeless riding (fewest skid patches) and stunting and jumping! I hit 32mph many times

no, one chain and one cog on each side, both fixed

Thanks meng but i still have de questions.
What do you mean by dialed, and "fewest skid patches?"
I wanted a higher ratio so i can start playing polo better. That shit is addicting!!!
pretti*ugli12.18.08 - 3:17 pm

Do 48/18 with a 48/21, one chain and a half link was all i needed. My real polo bikes are like, 34 18 or 34 20 though
Dialed means taking time to do the job exactly right just for your bike and wheel combo, takin into account everything custom. Dialed.

i thought its like 14, my gear chart at home said that. I use bigger tires though, whatever if you swithc your wheel out for both sides every week a few times for polo, like me, then you wont notice.

48/17= 17 skid patches. Thats what most of the people including myself have. I would like to bump it up to 19 and see what that feels like. Its all about the lowest common denominator when figuring out your skid patches.

Sorry, I couldn't come up with something juicier for QFT to fuck with ya. hahahaahah
Just wanted to confirm that skid patches mean nothing if you're changing your wheels around a lot.

BOTTOM LINE: dont use quick release axles, soma everwears, or skinny chains on yer fixie. Just had to drop that line about Somas, the sidewalls rip on those every time. If yer not rippin sidewalls on those yer not riding enough. Sorry i forgot im not lafixed

I dunno tallcans, I've been running Everwears for the last 6 thousand miles on my daily ride, I've NEVER had an Everwear rip a sidewall. EVER. Some have had some light cracking near the end of their life, cracking no more than any highly abused tire would
I've worn a few out (down to the threads, and I gots 15 skid patches) but most of that was due to egregious skidding.

Lucky you fuzz, I ripped the sidewalls in mine in less than 2 months every time, 3 times over, although that may have been due to bunnyhopping or something... the 35 bucks i've thrown away on each one made me bitter. I never skidded thru the top of them, to their credit

sezdaniel12.18.08 - 5:43 pm

I dunno, I hear of people talking baout it happening, Tallcans is the FIRST person who I've actually heard say it happened to them all i ever hear is "oh the sidewalls rip, it happended to someone I heard of once"
I've NEVER had a sidewall go bad. I've been running Everwears on both of my 700c bikes for about a year and a half. Maybe they made a coupe bad batches or something, I dunno.
I've seen cracking on my everwears when I let the pressure get too low and rode them then, but never through a sidewall. There is probably something related to how a person rides them or something, It's impossible to say, I hear people talk negatively about the everwears all the time, all I'm saying is that they are still the longest lastin tire I have encountered.

dont go for specialized armadillos if your doing to be skidding much either. i want some gatorskins they are the only tire i have heard 100% good about.

tbong, I've heard good things about those, and will prob try them as my new tire when i buy some.
FuzzBeast12.18.08 - 6:36 pm

I just buy the cheapest tire I can find and lean forward on a 46/15 (15 patches) when skidding. They do wear out faster but for half the price of the special skid tires you can carry an extra one in your bag and hardly ever need it.
If you skid through the top of your tire a lot... then take an old tire and cut the sidewall off... stuff the top of the old tire, minus the sidewalls, into the new tire. This homemade tire liner will keep your tube from squirting out when the outside tire is worn through and also allows you to prevent pinch flats on potholes even when running a little low on pressure. I run one in my front tire all the time.

damn matt i never thought of doing that shit. As i buy cheap tires all the time...sounds like some shit i am going to try...
pretti*ugli12.19.08 - 4:14 pm

On really thin tires it can be a bitch to get the old tire and the tube inside the new one.... it helps to cut about one inch out of the old old tires circumference so it doesnt bunch up inside the new one when you are mounting it.
