4iiii Frame Clearance: The Zayante+4iiii cranks will clear most, but not all, frames. The 4iiii module requires at least 10mm of clearance between the inside of the arm and the frame or bottom bracket mounted brake. Please see 4iiii’s FAQ or contact 4iiii for further information about frame clearance.
