Looking to replace my Rad Rover suspension fork with a rigid fork.

What adapter for the brake mount was used

Should be a $5 piece. Any bike shop should be able to help you with that.

I locked mine out since I only travel on paved roadways. The Supercell fat tires soak up the casual road imperfections really well even aired up at 18 psi (20 max).

Which supercell's do you have and how do you like them?
