Bicycle Mechanics - shimano or SRAM chain

Any significant differences for a person riding a road bike? I know the sram has a easy off link. the bike is a 9 speed ultegra/105.

thanks

Powerlink is the main difference and reason enough to choose SRAM.

+1 on DOS.

masterlinks are easier to work with for both installing and removing, but i really like shimano chains and the pin for reliability---it more closely acts like an original rivet, and in my own applications significantly reduces instances of chain suck and other chain problems. to be sure, the pins are more of a hassle than the masterlinks, but i don't really have need to take my chain on and off very often (and if it requires a serious cleaning, i just pony up the pocket change for a new pin).

Try Wipperman, their connex link is easier to assemble and reusable.

I'm using a 10-speed Shimano chain and Wipperman Connex link on the road bike and a similar 9-speed setup on the MTB. My shop friend convinced me everything would work best using a Shimano chain with an otherwise full Shimano drivetrain, but I can't stand the replacement pin system.

As a word of caution, the masterlinks deteriorate at least as quickly as any other links within a chain. By using them beyond the life of the original chain, you can speed up the deterioration of the chain within which you reuse them, and of the drivetrain.

The SRAM 9 speed is reusable too. As for easier to assemble, the Connex chain makes a really annoying noise if you assemble the link upside down. SRAM doesn't have this problem.

I used to use Shimano now I use SRAM. The main reason for switching is I was having problems getting the Shimano pins in and out without bending the links. So I switched to SRAM and have not had any regrets. I like being able to take my chain off and they have been easy to work with.

In the end I think the Shimano might make for a stronger chain (if installed flawlessly) but SRAM is much more convenient. Also, SRAM makes it possible to use my new favorite lube.

This sounds like a good thing. Better to have all the links wear at the same rate. If the Connex did not wear, it could skip around.

Easy solution: Install it right-side-up. The Connex is shaped like a kidney bean. You know you have it installed correctly when the Connex's curvature matches the curvature of the chainrings and cogs.
