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)

7 tooth cog?

Hey I'm thinking about getting a 22 tooth chainring and a 7 tooth cog for my Mercier Kilo TT. The problem is, I don't know where to find a 7 tooth cog, I've searched online but had no luck. I also would like to know if there's a fork that i could buy that allows me to barspin on my mercier. I don't give a **** if you think bar spins are for BMX, I'm asking for help. Thanks.

EDIT: If you were wondering, I want a 22/7 ratio because I heard it was the easiest ratio to wheelie with. If what I've heard is wrong, please let me know.

Like I have nothing against the tarck/bmx niche and have tolerated a lot of silly stuff on here, but this really upset me.

I sincerely hope it's a troll.

Either you're a troll or you don't really belong anywhere near a bicycle.

Look, bike chain is 1/2in pitch. I don't know for sure the OD of a fixed gear hub, but I'm pretty sure a 7 tooth cog is impossible.

Ok. Do u have any idea why I'm hearing about this 22/7 ratio? Should I just leave the cog/chainring alone? I'm just wondering cuz I can do keo spins now but can only get 4 pedals in on my wheelies.

You were probably looking at BMX ratios.

I've seen LBFG online and have thought about heading over there since I live in Anaheim. Kinda a random question, but does the focus cutter frame with the genesis fork allow you to barspin with a 700c wheel? Also, do you think the 7 tooth cog would be ridiculous or does it really help you on your wheelies?

Alright I'll admit it, I don't know **** about bikes because I'm relatively new to taking them apart and stuff, that's why I'm asking for help.

The smallest size I've ever seen in BMX drivers is an 8 tooth. Check danscomp.com as a reference. BMX drivers are only for freewheeling BMX hubs, not fixed gears. As far as threaded fixed cogs go, the smallest size that is physically possible is a 12 tooth. Sugino makes one, Ebtech makes one, Monty makes one, someone else probably does too.

If you want wheelies, get a 42 up front and a stack of cogs from 18t to 22t and see what works right.

What are you currently riding? What type of cranks, what type of hub? All the info you have can help us tell you what will work best for you.

PS: if you're trolling I will come to your house and **** in your pillowcase
