I headed North of Cambria on Highway 1 for a change. The chip seal north of Cambria, even though mitigated, is still a bit rough. It's not so much the rough ride as it is the constant vibration, especially at higher speeds. After awhile you get used to it. At least it's not nearly as bad as when some brain dead engineers at CalTrans back in 2013 decided chip seal on a popular bicycle route was a good idea.
Using 28mm tires at low pressure on my 700 makes the ride enjoyable and still reasonably fast.
