Sizing a New Chain - which method?

Which tyres for Paris-Roubaix? Whose time trial bike is fastest? Suspension mountain bikes or singlespeeders? Talk equipment here.

Thanks for the follow up Bustedknuckle.

The chain is a Shimano and using a "Quick-Link" as that is what is currently on there.

I never do this. Can't see why that's a good idea as you length will then completely depend on what angle you pull the mech cage to.

If I remember correctly Shimano recommends that the pulley bolts be directly vertical when in the big ring/small cog. Its been at least 10 years since I've not had the old chain to measure with so I might be wrong.

Here's a video of the small/small method: http://www.artscyclery.com/learningcenter/installshimanoroadchain.html
