9-26T cassettes.
i just discovered this today. i think i might have to get the hub and cassette and build a 700c wheel around it. not because i can spin a 53/9, but because i can.
enter: Shimano Capreo.
they say a 9-26 cassette on a 20" bike is roughly the same as an 11-32 cassette on a 700c wheel.
check it:

Whoa!!!
Beyond cool. I wonder if I can use my Campy shifters with that?
53-9. That's a big gear. Especially if you tried to build up some 700c wheels with it.

That looks like it was meant for the folding bikes with the 16-in wheels that are so popular over here...

It is, but I can see some crazy speed freak who wants to break the sound barrier on a 2 mile long, 25% descent, actually trying to do it with this setup using 700c wheels.

is this stuff avaliable in the US?
if not, I'm going to japan in the summer. Maybe I can get a few rear hubs and cassettes for all you speed freaks.

grrr... checking out the Shimano japan site and it says the OLD is 135mm. Cost of the rear hub and cassette would be 9,450 yen, or right now ~$83.

It's actually not quite as high of gearing as a 11-32 on a 700c wheel 53/9 on a 20" wheel is a gear inch of 118, 53/11 on a 700c wheel is a gear inch of 130.
53/26 on a 20" is 38 gear inch. 53/32 on 700c is a 45 gear inch.

who want's 9spd anyways
seriously though, at what point does a cog get to small? eventually there's only going to be 3 teeth in contact with the chain, i'd hate for something to slip on a sprint down a slight grade.
also you're kinda limited on what you can build, powertap is out.. wheels like the ksyrium with their special spoke's and hub's are out.
Interesting to have a 9spd cog though, it's designed for a specific use, this isn't it unfortunetly.

no, they're both "cans." i was saying i want one, not because i can spin a 53/9, but just because i can get one and build it up pretty easily.
krazyderek, while it wasn't actually designed with racing in mind, one of the bike friday techs uses it to race his 20" travel roadie.

Biggest gear i ever used was 60 - 12 on a 20 inch bmx. I could not even get to the point where it felt like i had no chain going down a grade 23 hill lol. That was not a bike to ride for any distance i used it for jumping. Go down the hill pedal till my legs felt like they would fall off and hit the ramp.

Thats about as few teeth as you can get on a free wheel or casset. I think the absolute lowest is ither 7 or 8. Bmxs could go as low as 8. as in previous post i ran 60 or 62-12. forget wich on the 60 it came off of a exorsise bike and it was a schwinn ..

They dont (well you can put on a 5 speed free wheel). I never road with any thing smaller than a 12 my self. Like i said i could not even get to a point where it didnt feel like there was much resistance going down even the largest of hills with the thing (possibly could now but not back then).

This seemed to fit here - no crazier than the rest of the thread.
He is a Dutchman going for an hour record for charity. Oh, with no saddle.
From Cyclingnews
Van Beek has been averaging 43 km/h during training, and says that it's quite possible to hold a position out of the saddle for three hours, provided the muscles are used to it. He'll be using a bike with a massive 68 x 11 gear and 205 mm cranks, but no particular aerodynamic equipment.

I would love to have a setup like this. I never go below 44/14/26, so I'm pretty sure I could push a 53/9/700c. Would come in handy on those long steep hills- at least going down hill.
