I do have a Rockshox Mag 21, but I ran that back in the days and was curious how the competition of the day worked out. Back then, I couldn't afford multiple forks, but today it's no problem. Also because 2nd hand value is way lower.
The Mag 21 has a threaded steerer, so that doesn't work out with the ahead stem I'm using. And sourcing a new crown with ahead steerer has proven difficult.
My shock is still not here, so I put some NOS Onza H.O. brakes on the RTS. It brakes like cr#p, but hey, that's how they rolled back then I have a longer steerer for my mag21's on the way, so maybe I'll switch the forks someday. OTOH, I really like this Pace fork,
