Thinking of going to the dark side...(14 posts)

Can I get a shimano cassette with a 16 tooth cog? Replacing 8 speed record with chorus or dura-ace. Agonizing over which to buy after riding my friends shimano bike. I do have mavic wheels I am using with an ultegra cassette and on colorado cyclists website they offer cassettes from shimano but I did not see a 16 tooth cog.
don't do it !!!C-40

Switching from campy to shimano and getting only 9 cogs! What a waste. Chorus is the best value, hands down.

Get a 12-25 ten speed setup. You'll have the 16 you want and a 25. If you go with shimano, a 12-23 cassette must be used to get the 16.
um ... what's so important about the 16?weiwentg

don't mean to sound like a dolt, but this is probably the 3rd time I heard someone mention the 16-tooth cog on the cassette.
too large of gap...C-40

If you don't have a 16, you will often find conditions where the amount of torque required to spin a 15 is too large and the cadence with a 17 is too high. It's a bad place for a 2 tooth jump. It's a 12-13% change.
Thanks,I needed that.koala

C-40, you have once again brought me to my senses, just like your advice on the thomson post, tried someone elses and I could not get knee over pedal. I was thinking chorus 12-25 as my current set up-42by23 is not quite adequate to get my aging a-- over the worst inclines where I live. Chorus and the lovely chorus post with enough setback... thanks, dennis

C-40: capiche.
but the Thomson seat post fits my bike perfectly, including knee-over-pedal and all that. funny.
same is true for 17-19CT1

That's why I built a cassette with the 18.

I find if I'm riding at 95+% level having the 18 is the difference between getting dropped and hanging.

I sure get a lot more use out of having a 16-19 straight block (13-23 9 speed) than I ever would out of having a 12. On flat ground, 90 rpm in a 53/18 is just about 21 MPH. Don't use the 16 that much except in TTs, going down grade, or with a good tail wind - I can't cruise at 23 mph (53/16 at 90 rpm).

The method I use is to use a straight block for as many gears as I can and then add one more tooth, then two, and so on. I had hopes, when I went to 9 speeds, for adding a 26 to my 12-13-14-15-16-17-19-22 eight speed, but it didn't work out so I'm now using a triple. I think the method makes pretty much sense both arithmetically and in real life for providing a cluster of gears in my normal range and help where I need it with easier gears.

One more question...can I use the Mavic 10 speed cassette on my classics pro wheels for chorus 10 or do I have to buy the Wheels Manufacturing cassette?
mavic 10...C-40

The mavic 10 only works with mavic's CC9 hub, that has a longer cassette body. The 10 cogs won't fit on a standard length shimano body.
Thanks again, your a great resource.n.m.koala

There is a DA 12-23 (w/a 16) and a 13-25 (w/a 16) in Ultegra.

The few Shimano 9 speed road cassettes with 16T cogs are built with the 16 in a two cog cluster. But, some of the Shimano 9 speed mtn. bike cassettes (like the XTR) do have individual 16's. My LBS is now trying to order a single 16 for me. I plan to buy the 13T with built in spacer, compatible lock ring, pull the 12 and 13 from my 12-27, add the new 13 and 16, for a close ratio 13-27 cassette.
