If you are working on double-unders, your jump rope makes a bigger difference than you might expect. A good speed rope is lightweight, responsive and built to rotate smoothly, so you can hold a consistent rhythm without working harder than you need to.
For functional fitness athletes in the UK, the choice usually comes down to how experienced you are, how often you train double-unders, and whether you want an everyday training rope or something set up for competition. In this guide, we compare the speed ropes available at WORKIT and explain what to look for.
Why Does the Right Speed Rope Matter for Double-Unders?
A double-under requires the rope to pass under your feet twice in a single jump. The rope needs to rotate quickly and consistently while you keep control of your hands and body position.
A basic skipping rope makes double-unders harder because it is often heavier, less responsive, or has handles that do not rotate smoothly. A dedicated speed rope is designed for fast rotations: lightweight cables, low-friction bearings and ergonomic handles all help you build a consistent rhythm.
The most expensive rope is not automatically the best choice. Beginners often benefit from a slightly more forgiving cable that gives enough feedback to learn timing and positioning.
What to Look for in a Speed Rope
1. Cable weight
Cable weight changes how the rope feels in rotation. Lighter cables move extremely quickly and suit athletes who already have reliable double-unders, but they give less feedback while you are learning. A slightly heavier training cable makes it easier to feel where the rope is on each turn, which helps timing and consistency.
2. Handle grip
Your hands should stay relaxed during double-unders. A good handle grips well enough to stop slipping without encouraging you to squeeze. Aluminium handles are common on premium ropes because they are light and durable.
3. Rope length
Too long and the extra slack slows your rotation. Too short and the rope catches your feet. Adjustable cables let you set the rope to your height and technique. RX Smart Gear takes this furthest, letting you choose your handle, cable weight, length and cable colour when you order the custom set.
4. Rotation system
A smooth bearing or swivel lets the cable turn without friction or twisting. This matters more as your double-under volume goes up, so if you regularly do high-rep sets, choose a rope built for fast, consistent rotation rather than a general-purpose skipping rope.
The Best Speed Ropes for Functional Fitness in the UK
RX Smart Gear
RX Smart Gear takes a highly configurable approach. The RX Jump Rope 2.0 platform lets you choose different cable configurations, and the custom full set lets you specify your handle colour, cable weight, length and colour.
That makes it the rope to choose once you know what you want from a rope. Run a heavier cable for everyday training while you build consistency, then a lighter cable when you want speed for testing or competition, all on the same handles.
The RX Smart Gear Custom Jump Rope Full Set is currently £62.99 at WORKIT, reduced from £78.97.
Best for: Everyday training, competition, and athletes who want a rope tailored to their own setup.

RX Smart Gear also offers the EVO FRE and EVO G2 handle systems, giving experienced athletes even more options when building their setup.
Velites Fire 2.0
The Velites Fire 2.0 is a strong lightweight option for athletes moving up from a basic skipping rope. It has 37g aluminium handles, a smooth rotation system and an integrated adjustment tool, and is marketed as the official jump rope of the CrossFit Games® and HYROX®.
At £44.99, it lets you upgrade to a dedicated speed rope without moving straight into the £60+ price range.
Best for: Beginners moving into dedicated speed ropes, intermediate athletes, and anyone after strong performance at a lower price.

Which Speed Rope Should You Choose?
Best speed rope for beginners
If you are still learning double-unders, you do not need the fastest rope available. The Velites Fire 2.0 is a strong starting point: it gives you the light, smooth feel of a dedicated speed rope without the higher price. Focus first on rhythm, relaxed wrists and consistent jumping.
Best speed rope for intermediate athletes
If you can already do double-unders and want more consistency and volume, choose the RX Smart Gear Custom Jump Rope with a training-weight cable. Being able to set the cable weight and length to you makes daily practice more consistent.
Best speed rope for competition
If your double-unders are already reliable, the RX Smart Gear Custom Jump Rope set up with a lighter cable is the pick from the current WORKIT range. You keep the same handles you train with and swap the cable for speed when it counts.
Best customisable speed rope
If you want to configure your rope around your exact height and training preferences, choose the RX Smart Gear Custom Jump Rope. Choosing your cable weight, length and handles means the rope fits your technique, rather than the other way round.
Frequently Asked Questions
What is the best speed rope for double-unders?
It depends on your experience. The Velites Fire 2.0 is a strong option for beginners and intermediate athletes. The RX Smart Gear Custom Jump Rope suits athletes who want a rope set up for everyday training or competition.

Look for a rope that is lightweight, adjustable and designed for fast rotation. WORKIT stocks speed ropes from RX Smart Gear and Velites, giving you options for different experience levels and budgets.
Are speed ropes good for double-unders?
Yes. Speed ropes are designed for rapid rotation, which makes them well suited to double-unders. Lightweight cables and smooth bearings make it easier to keep the speed and consistency high-rep sets need.
Should beginners use a speed rope?
Beginners can use a speed rope, but the fastest, lightest rope is not the easiest place to start. A slightly more forgiving cable gives useful feedback while you learn the timing.
How long should a jump rope be?
The right length depends on your height and technique. An adjustable rope lets you find what works for you, and RX Smart Gear's custom rope lets you specify your cable length when you order.
What is the difference between a training rope and a competition rope?
A training rope is built for frequent use and often has a more forgiving cable. A competition rope is set up for maximum speed and responsiveness. With RX Smart Gear you can run both on one set of handles by swapping cables.
I already own an RPM rope. Can I still get a replacement cable?
Yes. We still stock the RPM Speed Rope Replacement Cable while stock lasts.
