I will be running a 700 R4. I would like to cruise at 70 without running high RPM. According to the chart I have, with a 26" tire and a 4.56 at 70 MPH with a .7 overdrive I'd be running at 2,900 RPM. That sounds a little to high to me. Not terrible just seams a touch high. Again, I'm new to this
Thoughts?
