Any Carbon fibre parts without the weave obviously showing when the owner looks like he could do with spending the money on a gym membership instead. Again agree with @Exige short stubby leaver, mainly front break. Al Fagan said it right on a 44T video, anyone with one of those has never had to grab a handful of front break in a flap.
It was installed before my ownership...no idea if it was that make or not,but what i do know is it like sideways at every available roundabout in a controlled way.
