With the development of the XT M8000 groupset, Shimano had updated the venerable dual-sided XT Race pedals. With the M8100 groupset, Shimano updated some graphics but the pedal is virtually the same otherwise. As this platform is one of the most durable, effective pedal options for trail, gravel, cross and even road for some folks, there were real changes expected after M8000 version had seen some more significant upgrades from the previous version. Most crucially the design carried a new body platform which increased the pedal-to-shoe contact area by 2.8mm in width, and increased overall power transmission efficiency. At the same time the body was reduced in height for slight reduction in stack height.

With the M8100 you get all the XT level standards you expect: the anodized forged aluminum body, stainless steel hardware, chromoly spindle, sealed cartridge bearings and adjustable release tension. The single release (side action) SH-51 Cleatset is still packaged with the PD-M8000 pedals. Long considered the best value in SPD pedals, XT level offerings are durable, completely functional, resilient to trail damage, and serviceable. Don't disregard Shimano's overall level of quality and engineering when choosing pedals. A few extra grams isn't worth reliability issues. Mountain bikers, gravel riders, cyclo-crossers, and daily commuters swear by the durability and performance of XT pedals and the M8100 simply carries the standard forward with the new generation.
