MX Select MX100K EVO Pair review

MX100K EVO is the knurled-handle version of MX Select’s 10–100-pound-per-dumbbell Evolution pair. The U.S. distributor’s MX100 listing labels the variant “MX100K Evo Knurled Grip with Metal Dials.” Its important difference from the MX100R is at the hand: machined knurling on a roughly 29 mm steel grip and metal adjustment dials replace the R model’s thicker contoured rubber grip and yellow polymer selectors. The weight range and adjustment tradeoffs are otherwise shared, so pick the handle you actually prefer rather than treating the finish as a different-capacity package.

The strong point is capacity; the ordinary ladder is not fine

The official listing gives the supplied MX100 pair a nominal 10-to-100-pound range per hand. On the normal setting both end dials use the same value, and the page lists those equal settings in 10-pound increments. The ends can be selected independently. A one-position offset between them creates the manufacturer-described 5-pound total steps, which allows a nominal 95-pound load but does not keep the weight equal on both sides. Someone who requires a balanced setup at every repetition should use the equal-dial options and accept the larger gap; the finer offset choice and the equal-end requirement cannot be combined as if they were one plan.

That distinction matters more as the requested load increases. A broad “up to 100” headline does not mean five-pound increases all the way there with both ends matched. This base pair also starts at 10 pounds, so it is not a low-load set for people who need a five-pound first option. The manufacturer notes that real handset weights may vary from the marked selection by one to four pounds because of material and manufacturing tolerances. Thus the printed 100-pound setting is a nominal product selection, not an independently verified actual weight. A strict measured-load requirement cannot be confirmed from the documentation.

What the knurled version changes

The MX100K’s handle is described as machined, knurled steel at about 29 mm, and the selector dials are also metal. Choose it if a narrower, textured metal grip is the preference. The MX100R contoured-rubber handle is about 36 mm, so a person who wants a thicker, softer-feeling contact surface may prefer that version. A printed diameter does not settle fit: palm width, knurl preference, glove use and the actual feel of a metal surface are personal considerations that a product photo cannot answer. The two variants share the same stated weights and core mechanism, not a single combined “grip” fact.

MX Select describes its selector as a rack-and-pinion design with a positive lock. The official EVO user guide includes the MX100 in both handle forms. Its selection steps are practical but prescriptive: keep the dumbbell in its individual cradle, release the selector, set the desired load, and push the dial home to lock it before lifting. Two ends mean there are two controls to check. This is not a free-turn selector to adjust while holding the weight, and the manufacturer’s safety guidance warns that moving the dial or release button outside the cradle can release plates.

Micro plates and the supplied package

The base MX100K package is not a 105-pound kit. The distributor sells magnetic 1.25- and 2.5-pound EVO increment plates separately and describes a compatible add-on path that can extend the nominal MX100 setting to 105 pounds. These small plates can also add finer settings, but their presence and exact configuration have to be confirmed as a separate purchase. The matcher therefore counts only the advertised 10–100-pound supplied range; if your must-have is 105 pounds in the box, this pair does not meet that condition.

The U.S. seller’s FAQ says its MX dumbbells are offered as pairs and that each boxed handset includes a cradle and setup hardware. The compatible EVO stand is separately sold. The visible MX100K manufacturer image shows the MX100-marked pair, its steel knurled handles, metal dials and cradles. It is a polished isolated product composition; the source does not disclose whether it is a photograph or computer rendering, so the image should not be read as evidence of real-world dimensions or surface texture.

Limits, protection and alternatives

MX Select’s warranty page describes a two-year limited home-use warranty for the EVO line and a narrowly bounded accidental-drop provision: no higher than 30 inches onto protected plush carpet or rubber flooring. The owner pays shipping and handling for parts, and the company warns not to slam, throw or misuse the dumbbells. Hard, unprotected flooring is specifically outside the stated drop coverage. Since the retailer does not give a useful full-load length or clearance dimension for this exact 2025 MX100K, set aside enough room for the cradle, lifting path and adjustment rather than borrowing older MX Select measurements.

Shortlist the MX100K when you need a high nominal per-hand ceiling, are content with 10-pound symmetric steps or five-pound offset steps, and specifically favor a narrower knurled steel grip. If you want a softer, broader contact, compare the MX100R. If you will never need more than 55 pounds and want more frequent equal-end standard selections, the MX55 EVO may better match that use, but it is a different lower-capacity pair. If you need below 10 pounds, balanced five-pound steps throughout, or a guaranteed measured 100-pound physical load, neither MX100 variant is documented to satisfy that condition. The distributor page was marked sold out at the time checked; availability is not implied by this assessment or its exact-model search link.

The B-stock MX100 clearance page offers the exact knurled-metal-grip/metal-dial MX100K pair as well as the R handle. The seller reports possible cosmetic paint or handle-finish blemishes, the functional-defect portion of the MX EVO warranty plus two-year drop coverage, and final-sale/no-return terms; the page showed sold out on 2026-10-23. These terms do not alter the K handle’s load plan, but a clean model illustration cannot tell you which individual finish mark you would receive. Review the condition-specific guide before relying on a future clearance listing.
