I’m using the Chromag knees for all pedal rides, and Fox Launch Pro (d30 with hard shell removable knee caps) for bike park/shuttle. No complaints about either. Crashed whilst wearing them and each time they did their job very well.
I forget I’m wearing the Chromag ones most of the time. They are very well designed, never move around and offer more than adequate protection.
The Fox ones are a bit bulkier of course but that doesn’t matter given their intended purpose. Fit is great, protection is excellent however they can get a bit sweaty in the summer heat. Not a big deal when you’re not pedaling all day though.
