I had ARC 1100’s in 80mm and 60mm in my P5 and had many light speed wobbles rear, but also front. But also they catch quite a lot of wind. I more or less got used to it, but…….no riding a Cadex with the 4 spokes and the difference is so shocking. That bike wheel combo is ridiculous stable. We have had some very windy days last few weeks and all those things that happened with the ARC’s is no longer there.
