tks for clarifying that guys!

seems the chorus is the way to go for value

I already have mine but while getting some tools online I came across the Park CT-11 (Campagnolo Rivet Peening Chain Tool) from Tree Fort Bikes for just under $36. Quite cheap indeed. Just thought some might want to know...

Wow, you might need a different Campy 11 speed cassette soon.

BTW, I grew up in Valparaiso

What exactly is required to get the pin in and out? Anything special?

As I might look at the Park tool in that case...

Yah, I'll need a 12-27 but don't know that I can bring myself to do it !!!!

I am from LA (Calabasas). Small world.

The Colorado Rockies might force you. I shameless use a 12-27 x 53/39 combo which comes in handy in the San Gabriel and Santa Monica Mountains. I don't use the 27 and 25 very often but they definitely come in handy once in a while.

You need the Park tool CT-4.2 chain tool and the Park CT-11 rivet peening tool. Both are well made and do a great job but perhaps not as classy as the Campag

Best price from Ribble a week ago on sale extra 20% was still $140 shipped to the US for the Campagnolo 11 speed chain tool whereas you can get the Park CT-4.2 and the CT-11 for under $80 shipped in the US and use the CT-4.2 for other chains besides Campagnolo 11.

Both the Park and the Campagnolo tool have replaceable parts.

Think I might simply go the Campy tool.

Can't find the Park ones on Ribble

Might be able to get the Park one through your LBS. Might be closer to $50 USD each but that's a lot cheaper and you get the advantage of the CT-4.2 for other chains, including 7900 DA. I have some Campy tools but just couldn't bring myself to pull the trigger when the two from Park give me so much more bang for the buck.

I'm 42, I can do Tuna Canyon in 21 x 39 and I haven't weighed 135 since well before puberty.

I use a 12-27. You've got an additional gear over 10-speeds, so why not make life easier!
And don't forget there is also now a 29. You can buy it in a separate 3-cog cluster if you want. Just don't make that chain too short when you first fit it.

At 42 that's great! La Tuna in 21x39 is easy, Tuna in the sane is fantastic.

Most late model 10 speed chain tools will work fine with an 11 speed chain. To be sure, look at what part of the chain takes the force of the driving pin. The inner plates should not be taking the force, against the U-shaped center guide. The back of the chain should be taking the force. If the center guide is too thick, file it thinner, but be sure to file down the side nearest the drive pin. I've done this and my old Park CT-3 tool still works.

The only issue with any tool other than Campy's is they do not hold both ends of the chain together. It's critical that there is no chain tension if some other brand of tool is used. Otherwise, the pin will be misaligned and likely bend the guide pin, resulting in a failed attempt at installing the pin.

If a second joining pin is installed, the first one is left in place and the second put far away from the other one. If I install a master link, I remove the original joining pin.

I bought the Campy tool for about $140 in November 2008, since there were no other options at the time.
