2012 Langster to freewheel?

So i just got my 2012 Langster and i was looking at questions about converting it to freewheel and someone answered:

just buy a shimano freewheel and fix it on the original hub. this freewheel sprockets attach with a lock ring so they can be mounted on a Fixed/fixed hub.
i've done this mod on my 2012 langster

I don't really understand that so I Googled shimano freewheel and is this all i need to make it freewheel on the standard fixed/fixed rear rim?

Yep, assuming you have an unoccupied thread on your rear hub. Dicta freewheels are cheaper if you think this might be a temporary thing.

Thanks! Yes I do, and I think I'm going to stick with freewheel. My rear cog is 15t and I can only find 16t available to buy?

48/15 is a pretty high gear for city riding. 48/16 or 48/17 might be better but your chain might not be long enough to take a 17 tooth freewheel. 16 tooth should be fine.

Oh and make sure you get a healthy dollop of grease on the threads before installing the freewheel or it might never come off again!

By rear rim I assume you mean rear hub.
If it is a standard OTP Langster is should be a flip flop hub, but you say here it is fixed/fixed in which case the suggestion freewheel won't fit.

48/19 would be a good start.

16/17 is still pretty high.

Thanks Butters! I find the gear fine, i went on a 20ish mile ride when i got it and the gear didn't bother me at all.

Freewheel?. Fixed gear is where its at. The biker and the rider are one plus you need more skill to ride fixed. However as far as I knew they were flip/Flop hubs.

flip/flop, fixed/fixed, it doesn't matter as a freewheel will screw on to any of them.

Doesnt the Langster come with a Freewheel?

Take it down your LBS and get them to do it for peace of mind if you havent got the skills - shouldnt cost much

This guy seems obsessed with fixies like it's 2008 again!

Thanks for the tip though, so fixie bikes make you more at one with the road? Hmmm, noted. And they take more skill to ride you say? Gotcha.

Fixie bikes have made me one with the road on a few occasions.

There was also beer involved on quite a few of those occasions, so can I claim that beer makes me one with the road?

So if I've got a fixed/fixed hub, a freewheel should screw on over the top of the stepped thread? Will it be ok as there's not going to be much thread used?

Will be fine.
