going off the Shimano Res.. Crank Bros Mallet https://www.crankbrothers.com/product/mallet-2

and Time pedals Time Sport, velo luxe, velo carbone, Pédales, ATAC MX & DH both are double sided with the Spud mech in the center.

Spongy Trainers will give a good grip, around the slight Bump in the center .



Note: Nashbar gets Welgo to rebadge their shipments, so the cleats are commonly available by asking for Welgo Cleats .

I wouldn't have a Toe clip installed on the Underside, and thus dragging on the ground when using the Clipless side .

a Better plan, in that case, A QR Pedal , pop off.. the SPuD, and put on a Toeclip one , MKS makes that Easy
