Availability and condition
MX70 and MX100 EVO B-stock: condition, warranty and returns
MX Fitness Supply has listed B-stock clearance offers for the MX70 and MX100 EVO adjustable pairs. These listings describe condition-specific offers, not a new weight system. The useful distinction is whether you are comfortable accepting a possible cosmetic mark and a final-sale purchase in exchange for the seller's clearance terms. The latest manufacturer pages I checked showed both offers as sold out, so this is a guide to the recorded terms, not a claim that either is available now.
Start with the exact option, not the word “B-stock”
The MX70 clearance page offered the contoured rubber-grip, yellow-dial MX70R pair. It did not present a knurled MX70K option on that page. The regular MX70 listing describes that R configuration as a 10–70 lb-per-dumbbell pair; its same-capacity K alternative changes to a narrower knurled steel grip and metal selectors. The clearance page calls its offer a pair and repeats the MX70's base weight range. It is therefore best understood as the MX70R configuration under a different cosmetic and purchase-condition label, not a separate capacity tier.
The MX100 clearance page has two selector choices: contoured rubber with yellow dials (MX100R) and knurled metal with metal dials (MX100K). Both are versions of the 10–100 lb-per-dumbbell MX100 pair. Here, the handle choice still matters: pick the R or K assessment according to the exact option selected, rather than treating a photograph or the generic “MX100” heading as proof of which grip is supplied.
What the seller says about condition and coverage
On the MX70 page, MX Fitness Supply says the units are new and unused but may have minor cosmetic blemishes to paint or handle finish. The MX100 page also says the finish may have minor cosmetic blemishes; its wording does not make the same “never used” statement, so do not transfer that assurance from the MX70 offer. Both pages describe the MX EVO warranty for manufacturing defects that affect dumbbell function, include two-year drop coverage, and state that B-stock sales are final with no returns or exchanges. Those are seller-stated terms for those particular pages; check the current item and written terms again if a new offer appears.
The descriptions do not grade an individual unit, identify the location or size of a blemish, or guarantee that the mark will be on an unseen area. Nor do they give a condition-specific sample image that can establish what a future buyer's pair would look like. If a scuffed finish would bother you, or you need the option to return a mismatched handle or cosmetic condition, the final-sale term is a meaningful downside rather than a minor footnote.
The B-stock label does not change the training tradeoffs
Clearance condition does not create lighter or heavier selector settings. The MX70 base pair still tops out at 70 lb per hand; its ordinary balanced positions are 10 lb apart, while using different end settings changes total nominal load in 5 lb steps and leaves the dumbbell uneven. The MX100 has a higher 100 lb base ceiling but the same broad distinction between equal-end settings and an offset. Optional magnetic micro plates and the MX70-to-100 conversion parts are separate accessories, not part of a B-stock pair just because the listing links an upgrade. If a precise balanced ladder is essential, read the relevant model review and its supported plan before choosing either clearance offer.
For a 70 lb ceiling and a preference for the thicker contoured rubber handle, the MX70R review is the relevant product assessment. If the program calls for loads above 70 lb per hand, compare the MX100R and MX100K reviews instead and decide the grip separately. A cosmetic condition offer is not a reason to buy a higher-capacity model you do not need, and it does not resolve the manual-revision or accessory-compatibility questions discussed in the model guides.
Use the listings conservatively
The official MX70 and MX100 product pages use clean model illustrations to identify the ordinary configurations. Those images do not show the blemishes on an individual B-stock unit and should not be read as condition photographs. The B-stock pages were marked sold out when checked on 2026-10-23. If a seller re-lists one, verify the handle selector, pair contents, current stock state, return restriction, and exact warranty language on that offer before ordering. If the details are not visible, ask the seller rather than assuming a past listing's terms still apply.
For the underlying load range and grip comparison, read the MX70R assessment, the MX100R assessment, and the MX100K assessment. The MX70 versus MX100 guide compares supplied capacity and loading options without counting add-ons as included weight.
