In this article I will review the Shimano Deore XT PD-M8100 SPD pedals, which are the default for mountain bike and gravel pedals. The new limited edition Shimano GRX SPD M8100-UG pedals are basically the same Deore XT M8100 SPD pedals.
I also have two pairs of Shimano XTR PD-M9100 SPD pedals (which we discounted) that are a bit lighter for the top end group and used by Pete Stetina on his Canyon Grail gravel bike.
