Weight changes and ownership

MX Select EVO capacity, offsets and optional micro plates

MX Select’s current EVO dumbbells make two distinctions easy to miss: equal end settings and offset end settings are different loading plans, and a separately sold micro-plate kit is not part of the base pair. Both matter when you compare the MX55 and MX100 families.

Start with what the base pair supplies

The MX55 EVO is listed from 10 to 55 pounds per dumbbell with equal-end selections in five-pound steps. The MX100 EVO is listed from 10 to 100 pounds with equal-end selections in ten-pound steps. Those capacities are per hand, and the U.S. distributor says MX dumbbells are sold as pairs. Neither family starts below 10 pounds. An MX100 is therefore the more capable choice for heavier nominal loads, but its base balanced ladder is coarser—not simply a larger MX55 ladder.

Offsets add choices but change balance

The handle has independently adjusted dials on its two ends. The manufacturer says setting one dial a step above the other can add an intermediate nominal total: 2.5-pound changes on MX55 and five-pound changes on MX100. Those extra numbers require an unequal arrangement of plates. They may be useful when a particular intermediate load is important, but are not the same as a matched plate stack. If equal loading is essential, select only the values supported by the equal-end plan and do not use the offset’s smaller gap to satisfy a strict balanced requirement.

Accessories are a separate decision

The EVO magnetic micro-weight plates attach to the gear housings and are offered separately. The distributor describes compatible 1.25- and 2.5-pound kits and an MX100 route to a nominal 105-pound endpoint. The MX55 has its own accessory limits. Do not move an endpoint, exact weight or included-capacity answer simply because a compatible accessory exists; first determine whether you are buying the add-on and which model’s instructions apply. The MX70-to-100 conversion kit is also an expansion accessory for MX70 owners, not a complete pair.

Choose the handle as well as the capacity

Both current EVO capacity families are offered with a thicker contoured-rubber option and a narrower machined-knurled metal option. The MX100 page lists about 36 mm for the contoured grip and about 29 mm for knurled. Those figures help distinguish the versions, but do not substitute for trying the handle if diameter or surface texture is decisive. The MX100R and MX100K have the same listed weight range; the grip selection does not supply an extra loading stage.

Read and follow the adjustment directions

The official EVO guide names the MX100 in both grip styles and explains that the handset is adjusted while sitting in its cradle. Release, turn, then press the selector into its locked position before lifting; do not move a selector while the dumbbell is out of the cradle. The seller lists an individual cradle with each handset, while the compatible stand is a separate item. The seller also warns that actual weights can vary by one to four pounds from their dial labels. Keep that distinction visible if an exact measured load is essential. Read the MX100R assessment, compare the MX100K, and check the MX55 base range before choosing a requirement.
