Alright, I have ideas. But before I can spill the beans, I’ve a few questions about your spec and design constraints:

1– are you amenable to more cable stops being clamped onto that lovely paint job?
2– must the bell stay on the stem?
3– is that front brake nutted or recessed mount? (looks recessed but want to confirm)
4– how much clearance is available between tyre and fork crown?
