Remind me of the advantages?
I never understood the use of those small black plastic guards: they won't keep the disc dry, for the most of that is exposed to the weather anyway, besides it's stainless...the headers will get wet also, guards or not.
The advantage of "flipped" calipers is a better weight distribution, makes for lighter handling, and a cleaner look of the front side.
All bikes have nowadays their calipers behind the fork legs...why?
