Hello folks, first post. We've had our Co-Motion Speedster for about 3 months now. It came with some 700x28 tires rated for 105psi. I changed to some IRC Duro/tri's that are 700x25 rated at 115psi. The rim is a litte wide for this tire and kind of swallows it a bit.
I'm now waiting on a new set of wheels built on a narrower deep V rim as I want to run narrow high pressure tires.

Here is my question:

I'm happy with the way the 25c's handle and preform but, am wondering if a 700X23c with say 125psi is ok for tandem use?
