Momentum BMF speed rope: specifications and replacement decisions

This page preserves the Momentum Gear Bad Mother F***er (BMF) rope reference and original adjustment video. WOD Fever no longer sells or fulfills this rope. Use the model details to identify an existing rope or compare a replacement; purchases occur with an outside merchant.

Model specifications

The manufacturer’s BMF listing checked on October 22,2026 supports the following details. They describe the listed configuration, not a promise that every used or later version has the same parts.

• Aircraft-aluminum handles, 4.5 inches long; original listing describes a military-spec anodized finish.
• Self-lubricating nylon bearings/bushings.
• 7-strand PVC-coated cable, 10 feet 10 inches before sizing.
• Manufacturer-listed total weight: 3.25 oz including the cable, not the weight of the handles alone.
• Tool-free length adjustment and a replaceable cable.
• Manufacturer describes USA manufacture. Anodized handle color can vary in hue.

Adjust first; confirm parts before replacing the cable

The original video below demonstrates this rope’s adjustment. Keep enough cable to test your preferred length before making an irreversible cut; follow instructions for your exact hardware. Adjustable length is limited by the installed cable and retention mechanism—it is not an unlimited range.

Inspect coating, ends and retention hardware before use. Rough surfaces can wear the coating. For a replacement, confirm the coated cable diameter, end/retention arrangement and usable length against your actual handles. A cable described only as “speed rope” is not proof of compatibility.

Momentum’s replacement-cable reference identifies a part but does not publish enough diameter or attachment detail to settle every version match. Ask the supplier to confirm the fit and exact warranty/return terms. This is an untracked manufacturer link, not confirmation of stock.

Keep the BMF or compare a different rope?

If your handles work and the correct cable can be confirmed, compare the replacement part and full-rope cost before replacing the whole rope. For a different design, compare handle length, cable feedback and adjustment method in our current speed-rope buying guide. Its merchant options are alternatives, not interchangeable BMF spare parts.

Handle feel and cable feedback are personal. This rope does not guarantee double-unders, faster skill acquisition or suitability for every workout. WOD Fever has not performed a hands-on comparison.
