Tandem Cycling - Campi chain question

Has anybody had experience using the new 5.5mm 11-speed Campi chains? Seems like the 6.9mm 10-speed chains, shifters and cassettes are becoming extinct, just like the 9-speed components. I am particularly interested in anyone's observations/problems using 5.5mm chains on a 10-speed cassette.
Thanks

I just checked several of my vendors and they all have huge quantities of Campy 10 speed shifters, chains, chain rings, shifter parts etc.
I think with the 11 speed here alot of shops may stock the 11 speed and only special order the 10 speed.....I know that's how we are doing it.

I should probably re-phrase the question. Are there any advantages to go to a 11-speed 5.5mm chain (using my 10-speed cassette), rather than continue to use 10-speed 5.9mm chain?

Simple answer NO
Better answer, would start by asking why would you want to? Thinner chains are usually more flexible and wear faster (not always but usually). A weaker chain + added torque of two engines = Disaster waiting to happen.

You answered my question - Thanks

WheresWaldo is right. The 11 speed on a tandem would either break or have no service life.
I switched to Super Record 11 on my single and the first chain went from .5 to .75 in 700 miles.
So I'm thinking every 1,000 miles the chain will need to be replaced.

Wow. That is some serious wear. I think I'll stay with my 5.9mm 10-speed chains on my road bike and on out tandem. Thanks for the post
Cheers

Not that anyone cares, but I've found Shimano's "Super Narrow" 10 speed / 6.1 mm chains work just fine on Campy 10 and are often times cheaper / on sale.

Note that I use the Shimano chains on my single bikes with Campy rear wheels but stick with the hybrid Campy 10 derailleurs & shifters + Shimano cassettes and chains for our tandems: more cassette options and less expensive.

TG, you have always provided great insight and a willingness to share you knowledge, so your input is always worth it.
Don't know what you get your chains for, but here are links in the UK that I have used.
http://www.wiggle.co.uk/ - Record 10 chain delivered in USA $53.00
http://www.probikekit.com/ - Record chain delivered in USA $47.00
Prices can change depending on the exchange rate

I'm a Gold or Platinum member at Wiggle or something like that... Good stuff, great prices, free shipping and here about as fast as any domestic Etailer.

However, if you keep an eye open for them you can find even better pricing on Ultegra/6600 or DuraAce/7800 chains for under $30: http://www.coloradocyclist.com/product/item/SSFEJWFS

When I find those kinds of deals I usually stock up. I do the same with tires, tubes, handlebar tape and cables -- often times just buying 10-packs on tubes or bar tape which then lasts me for a couple years.

Anyway, getting back to the UK firms... some will recall that I scored my Tubus Fly rack for about £37.58 and my Ortlieb panniers for only £79.65: unbelievable deals to be sure.
