I just purchased a standard bar (Oval Concepts M200) and standard grips (Ergon GE1) to replace the IsoZone stuff. IsoZone is making no difference for me, and I don't like the non-standard bar which restricts the type of grips and bar ends I can install. Should have the new gear installed sometime next week.
I just replaced my pedals with the Origin8 Ultim8 Slimline Platform. We'll see how these work. When I purchased them all I knew was that I wanted a wide platform pedal with replaceable spikes so my foot wouldn't slide.
