Project 321 ISO Disc Boost Front MTB Hub
Project 321 front MTB hub from Wheelbuilder.com Project 321 Front Boost ISO Hub

This Boost offering from Project 321 is a wider spaced hub specifically designed for 115x15 forks. Project 321 set their Boost front hub apart by moving the left flange out by 5mm but actually leaving the right flange in the same position. In doing this, spoke tension ratio is much closer to equilibrium, yielding a stronger and stiffer wheel.
