Where can I get an alau. cogset for my Campy 10 speed?
Is there someone in the US that has them?
Thanks in advance, David

Hey popawheelie,
try triathlete zombies located in santa monica california, they have tiso cogset's and cassette's for your campy setup there . Ask for jose he will help you out, and this shop is full of weight weenie stuff.

120g for 12-25 10s ... and only 80€

I am still looking for a ramped alau. 11-21,23,23 cogset for my bike.
Some of these places want close to $ 250 for one!!!
It seems the single piece ones are like 11-26 or bigger!
I don't want to run another chain settup and I like my close ratio 11-21
Would my small cage derraileur have to change?
I want to get below 6 kg. I guess that is a good goal.

I use a medium cage Record Deu. and have actually ran a 12-29 without problems (for that 18-20% grade on Hogpen), although I wouldn't recomend it. You shouldn't have any problem running a 27 or less though.

Where would you buy one? Tiso? Other? I like the one piece idea because the set acts as a single unit.

Look at http://www.amclassic.com/Cassettes_Alum.html
or

T.A. is also producing alum. cassettes, but 10 speed ,i dont know.
Alu casettes are just good for 4000 km, not longer

I asume you are in the US. Go to www.cyclininnovations.com for the Tiso cassette. Or send them an email at info@cyclinginnovations.com. The guys name is Andrew. I beleive that www.hi-techbikes.com also has Alu. cassettes as well.
