Parts E-Thirteen ESpec Plus Chain Guide

Most e-bikes use a different ISCG standard to a ‘normal’ MTB as the motor gets in the way so an ISCG05 chainguide won’t fit as the bolt spacing is different. Most manufacturers have their own ‘standards’ to work with the dimensions of their motors but E-Thirteen has come to the party with an aftermarket option that improves upon some of the existing designs out there.
