Bicycle Mechanics - Smallest gear cassette out there for a Road Bike...

Hi, I went to my local bike store this morning enquiring about a new cassette for my road bike and I told him I wanted the smallest possible, and the smallest they offered was a 11-21 if I can remember correctly.

Do any of you guys know whether you can go smaller than 11-21 gear cassette to add more restistance???, And if so, Could you please post the link to where I could purchase one from...

Any comments would be a appreciated, Cheers...

Cogbox: For the requirements of the professional bike shop Miche offers cog boxes available in 3 drivetrain; Campagnolo 9 or 10 speed, Shimano 8 or 9 speed and Campagnolo 8 speed. All cog sizes from 11 to 28 are available in quantity of 10 each with first position cogs available 11T to 18T also in quantity of 10. The box includes 200 spacers and 20 lockrings.

are you looking to ruin your knees or something?? good luck!!

the purpose of the cassette is to give you OPTIONS, not to torture you. even if you do want to do power intervals, you can't go any lower than 11T.... so why not just spend all your time in the smallest cog??[/

Hmmm. What are you planning to do with such killer gears? deliriou5's comments make sense: don't overdo it. But if you are superhuman, perhaps you could look for a 10t sprocket and a 55t chainring. ;)

If you need an even bigger gear you will need to change your big ring fi you already have the 11t in back. 56-58t will be about the biggest, easy to find, chainrings. They will degrade your front shifting some and the chain will rub the ring when in the small ring and smaller cogs( the last 2-3)

What are you running for a big ring? Like a 53? I can't imagine you'd be able to spin out an 11-53 for very long, and if you can, look out Lance! The gear ratios that are most popular are that because a great many people tried a lot of different stuff over the last hundred years or so, and the consensus was that 11-25 or thereabout works the best. Make sure you have a large enough chainring and an 11 cog in back and you should be set. My .02

Thankyou for the replies, really appreciate it...

Are you looking for a straight block?

I think he needs a V-Twin.

That Miche kit... What is it about? About $2000+ US?

Are the Shimano packs ramped like the Hyperdrive stuff?

Some recumbents have 62-64t large chainwheels, needed because of their 20" wheels. www.hostelshoppe.com has a variety of larger CW in stock.
You will need a clampon F der though. Steve
