julians,
I don’t know about Hope ones but they work fine with Superstar floating rotors. Tips of the ally spider are extremely close to the caliper but they do fit.
Superficial,
I think you’ve misunderstood. Inboard = towards the stem.
I ran the old XTs with Shifters outboard.
i.e. brake lever > shifter clamp > an inch of bare bar > grips. This was great for single finger braking.
The issue I had with the new XTs was that the shorter brake lever necessitated bringing the lever further out to where the shifter clamp needed to be. Working around that, neither position on the adjustable SLX shifter clamp felt right.
I’ve found the solution for the new XTs now: Remove the shifter mounts from the shifter bodies on both sides and swap mounts over, refitting them so the mounts point outward rather than inward. This allows the mount to sit inboard of the brake lever but with the shifter body/levers remaining close to the grip.
i.e. reversed clamp > brake lever > an inch of bar > grip.
