Done 600km with the +20mm Hagons on the GT, including a 180km with a pillion yesterday.
Very pleased with the shocks so far - less wallowing, more controlled rebound and not as harsh on big compressions (longer travel helps).
The bike tips in a bit quicker and changes direction more easily, which takes a bit of recalibration, but the bike is slow handling in stock form with the big front wheel so it’s a welcome change.
I’d go as far as suggesting this bike should come standard with 380mm shocks, for anyone over 5’10”. (I’m 179cm and comfortably ball-footed solo or flat-footed with a pillion).
