Yeah the stem works fantastic, makes the steering very precise and stable, don’t have any issues with lack of grip on the front wheel with the passlia
What fork are you running on the Radical?
Cane creek helm mk2, air… best fork I’ve own, can adjust the travel myself, from 160 to 120, and service it myself. Super supportive and supple and boy can it take some big big hits and still stay smooth and don’t blow your hands off the bars
