Chain Length(11 posts)

Chain LengthSome Guy

How do you figure out how long a chain you need? I've heard that you put the chain on the large chain wheel and largest sprocket and then add 2 links to this length. Is this right? I'm using Shimano 105 53-39 chainset and 12-25 9spd cassette. (nm)Racer-X

... I've actually used the long formula with great success... never a problem (It's not too bad if you program it into a calculator or PDA).

you're asking for trouble. You definitely want your cassette to match your shifters. You might be able to get away with some of the other mixing and matching that you suggest, but I bet you would regret it later. If you already have Shimano oriented wheels, just get Shimano. It's not a very big deal. Parts are parts.

I was just looking at running 9 speed Campy wheels on my Shimano 9 speed drivetrain, and its possible.
Wheels Manufacturing ( makes alot of cassettes for different setups, even 10 speed stuff...

If you don't already know the answer to your questions, or are unwilling to spend your own money on parts with which to experiment, then go with a homogenous setup.

Not sure this is a good plan. Why would you spend that kind of dough to possibly compromise your performance? Yes, you can buy converter cassettes and the like, but Shimano and Campy have gone to great pains to make sure their stuff is not compatible with the other. Maybe it can be done, but is it worth the hassle?

You can mix the two, however the cassettes will be relatively expensive. I run Campy 9spd with Shimano compatible wheels using a Wheels Manufacturing cassette and a Dura Ace chain. I know that you can run a Dura Ace crank and BB with the same setup (I use a Record BB, crank, and front derailleur). The system shifts extremely well ( I actually think it shifts better than Campy EXA and Ultra drive cassettes). The only downfall in the cassettes are $100 each; this is not too bad if you planned on buying the ti/steel Campy cassettes. Excel Sports and Branford Bike stock the Wheels cassettes.

If you want to run a campy setup in 9 or 10 speed, you can purchase an aftermarket cassette from Wheels manufacturing called the Accelerator. This cassette is nothing but either an Ultegra or dura Ace cassette that Wheels manuf has remachined the cog body and changed the spacers so that the new cassette cogs exactly match the spacing required for a Campy drivetrain. The beauty of this setup is that now you have a cassette which has the Shimano spline pattern necessary to buy just about any wheelset going. I have been running my Campy Chorus 9 with this cassette for about 6 months now and I truly think the shifts are smoother with this cassette than my original Chorus cassette. Beware though, if you do this you should not run it with your Campy/Chorus chain. Use either a Shimano train or a Rholoff chain of you will not get smooth movement by your chain over the remachined Shimano cassette. This product truly gives you the best of both worlds - campy drivetrain with Shimano hub wheel availibility.
