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)

Smallest freewheel size

Any leads on the smallest (in teeth) freewheel available for a normal track hub? (in this case a Phil Wood Kierin hub)

It's running a 12t fixed at the moment which is dandy but I'd like to try a free-wheel set up for longer rides. I recall seeing evidence that the 14t is the usual smallest but 13's can be had - I just can't remember where I read it or who makes the smaller ones.

I don't want BMX ones as they're too small.

Oh - this being for this - my crazy fixed Brompton folder:

I love Bromptons so much. This super nerdy guy comes into my work a lot. He always folds up his Brompton and brings it along with him.

When i said BMX hubs are too small I meant threading not teeth - ideally I'd like the same but I know this isn't realistic; maybe I need a different hub so I can go for the small sizes.

Anyone know where I can get 115mm OLN rear hubs in 32h?

I've always wondered. My buddy has a 9 tooth cassette on his 20". Are they shimano style hubs like on road bikes?

The smallest standard freewheel you can get is 15 tooth, and the only place I've seen them is harris cyclery. 16 tooth is the smallest from shimano and ACS. Cheapest option by far.

You can go down to 13T if you use a standard cassette hub, (or 11 with a cassette cog), but it'd be hard to mod it to 115mm spacing.

Your best bet is to find either a BMX cassette hub or BMX flip-flop (go down to 10T with smaller threaded side) with a 3/8" axle and file it flat.
