11t single speed?

I know they're almost impossible to find,

But I'm looking for a 11t for a single speed conversion.

Any info would be great.

I guess the first question should be, single-speed conversion of what?

Road bike, freewheel, replacing a cassette.

There's a reason singlespeeds come with a 16T. Because you set your ratio by selecting the chainring, there's no need for that small of a cog. You'd need to run like a 38T chainring with an 11T cog to be able to get up even a mild grade.

Who can't get up a mild gradient with gears higher than 38t-11t? hahaha
Maybe I'm asking the wrong person about the 11t

I hadn't previously seen the nonsense thread about the 70T chainring. Somebody's gearing up to do 50mph. So umm...

If you are replacing a cassette, why not just use an 11 tooth ring off of a cassette along with a single speed conversion kit? I think Jenson sells the 11t cogs for around $3.99. Add the spacers from the conversion kit and you're all set.

If you’re looking for a thread on freewheel with 11t, you won’t find it. If you’re doing a multispeed freehub conversion and looking for an 11t sprocket (I’m assuming shimano/sram) well, you likely won’t find it. The easiest option I can think of would be to modify the standard 11t sprocket so it will slide all the way on the the freehub body and be used with a conversion kit. I wouldn’t recommend that though unless you have access to and experience with matching equipment. There’s a reason an 11t stand-alone sprocket likely doesn’t exist. Use a 12t, problem solved.

A real man would use a BMX hub so he can get a 9T cog.

A first position sprocket won’t slide all the way onto a freehub body. It has ‘stops’ and would need to have those precisely machined off in order to be useable.

He wants to pair the 11t cog with a 70t chainring.

I missed the part about a 70 tooth. Same OP as the other thread? Pbbbth. Nevermind. I wish him luck, he'll figure it out soon enough.

Any poseur can climb a mild grade in a 22/11.

As far as I know, the 11T cogs will only work in first position, and requires the notch on the end of the Shimano freehubs.

Perhaps they could be modified to work with extra thin spacers.

Chainline would be an issue. But there are a couple of different freehub widths. For Shimano hubs, the 7-speed freehubs are the narrowest that are commonly available that accept hyperglide sprockets & lockrings.

A few brands have "single speed" freehubs that are closer to 5 or 6 speed width, that could possibly be used.

I have some Capreo freehub bodies that are also narrow, and could potentially be modified to accept an 11T sprocket. But, the Capreo freehubs attach slightly different than other Shimano freehubs, so you'd be needing to replace the hub too.

That's what I was thinking.

It looks like there is a 11T Odyssey Driver

In many senses, the BMX Driver's look a lot like the road sealed bearing freehubs (not Shimano), and it is quite possible that one could be substituted with a bit of tinkering.

Odd, the pawls look backwards in that Driver from Down Under. Perhaps they do things backwards down there.

Overall, I think the smallest freehub/cassette style single speed sprocket that is available is 12T, and as mentioned, you could probably adjust your chainring to work with it.

Yep, it's RHD (right hand drive)

Then get a Hollowtech crankset & install it backwards. Easy-peasy!

Aren't 99% of the bikes RHD? I.E. chain, chainrings, sprockets all on the right side of the bike?

Which would mean that one would slip, unless one is backpedalling.

Thanks for your reply.
That was my original plan, however all 11t rings on cassettes are designed to be stationary at the end. I could remove the rest of the cassette, however I won't be able to shift it on the hub.

Oops, RHD is the norm. That photo should be LHD.

Many BMX hubs/drivers/freewheels, etc are available for either side.

This Odyssey driver has symmetrical pawl cubbies so you can flip the pawls for LHD or RHD:

76x12 is almost as high a gear as 70x11.

This is a 76, along with a 53T little ring:

[MENTION=495208]tellmethetruth[/MENTION] you're also gonna want to choose a saddle carefully for this build as its gonna have to support your evidently enormous manhood

Honestly though, build your bike how you want man, don't let all of us skeptics get in your way. I just ask that you follow up once this build is done. Everybody on this forum loves bikes, whether they appeal to the popular formula or are a bit kooky. I think most of us here just want to see what you come up with!

good luck with the build
