FAQS

HEAVY AND COMPACT
These are heavier and more compact than most adjustable dumbbells on the market. An adjustable dumbbell that can go up to 125lbs and is only 18.3" in length is pretty much unheard of. -
EXTREME DURABILITY
Both the dumbbells and cradles are made with full metal construction and have been extensively drop-tested from every angle. -
SPACE SAVING
Adjustable dumbbells take up a very small footprint in your gym when compared with a 10-85lb, 10-105lb, or especially a 10-125lbs dumbbell set. -
FAST WEIGHT CHANGES
Quickly and easily change weight in 10lb increments by popping and sliding the magnetic pop-pins into place. Add 2.5lb micro-adjustment plates to increase weight by 2.5lb or 5lb increments up to 125lbs. -
EXPANDABLE
The basic pair of adjustable dumbbells spans 10 to 85lbs, with the option to add more plates later up to 125lbs. The cradles expand with the size of your dumbbells, too. -
NICKEL-PLATED HANDLES
Nickel-plated handles are 34mm in diameter and feature a volcano-style knurling pattern that provides plenty of grip without being overly aggressive.
Adjustable dumbbells take up less space than a set of fixed dumbbells. A pair of 125lb REP® x PÉPIN™ FAST Series™ adjustable dumbbells can replace 23 pairs of fixed dumbbells (10lbs-125lbs).
Most other products cannot go as heavy, or if they can, they're slow to adjust.
Our dumbbell retains the shape of a traditional dumbbell, with guide rails that add function. Other heavy adjustable dumbbells are bulky or oddly shaped, sacrificing the feel of a traditional dumbbell.
Other quick-adjust dumbbells use fragile plastic parts that control the adjustment mechanism, and if they break, the dumbbell is useless.
Other quick-adjust dumbbells that advertise all-metal construction typically still have hidden gearing made of plastic. Or if it is metal, it's still a small, moving piece hidden from view with unknown, real-world strength. Our adjustment mechanism is a thick steel bar. It's simple to use and simple to understand; that's why it's incredibly strong.
Other adjustable dumbbells advertising drop resistance typically only drop them straight down—the easiest test. Edge drops are a tougher measure of durability in real-world testing, and we incorporate those in our durability tests.
Our dumbbells are expandable by simply buying more plates. Many other systems lock you into whatever size you originally buy.
We're using premium materials throughout. Nickel plating on the knurled handle, combined with strategic use of Cerakote, powder coating, and stainless-steel hardware choices, all create one of the most durable and beautiful adjustable dumbbells ever made.
While there are some similarities – such as volcano-style knurled, steel handles; micro jumps of 2.5lbs or 5lbs; extensive drop-testing; space-saving capabilities; quick and easy weight changes; the ability to expand weight over time; a max length of just over 18”; and a pro-style shape with a flat bottom to prevent rolling – there are many differences. A few of the main ones include:
The weight capacity: The QuickDraw™ starts at 5lbs and goes up to a 60lbs max. The REP® x PÉPIN starts at 10lbs and tops out at 125lbs. The QuickDraw™ comes in the following sizes: 30lbs, 40lbs, 50lbs, and 60lbs. The REP® x PÉPIN in 85lb, 105lb, or 125lb pairs.
The materials: The QuickDraw™ has steel switches and an almost-all steel construction accented by strong, nylon composite. The REP® x PÉPIN dumbbells and cradles are constructed entirely of metal, with UMHW liners to prevent steel-on-steel contact.
The mechanism to change the weight: The QuickDraw™ uses a Lock-N-Load switch; you can flip one switch at a time or multiple switches all at once for fast weight changes. The REP® x PÉPIN uses a magnetic pop-pin.
Design: The QuickDraw™ dumbbells are entirely new to the market, whereas REP® x PÉPIN dumbbells were created as a partnership between REP® and a Canadian inventor, as part of the REP® Inventor Series. The original concept of these dumbbells started with Pépin, and REP® recognizes and honors his exceptional work in the fitness industry.
REP® x PÉPIN™ FAST Series™ adjustable dumbbells start at 10lbs rather than the original's 20lbs. This was achieved by incorporating high-strength aluminum in the headplates of the handle.
The handle side rail coating was changed to Cerakote with a high-contrast laser-etching to better see the weight markings.
The cradle is now expandable.
We did a lot of "invisible" work alongside Pépin himself to turn this originally handmade product into one that is manufacturable, to make it accessible to a wider audience -- without sacrificing quality.
No. Due to subtle changes in the design of the dumbbell and cradle, original PÉPIN™ FAST Series™ components are not compatible with the REP® x PÉPIN™ FAST Series™ adjustable dumbbell.
They are sold in 85, 105, and 125lb pairs, but the 85lb and 105lb pairs are also expandable. If you buy the 85lb or 105lb pair, you can later buy more plates up to the 125lb max. You can also easily expand your existing cradles.
Each REP® x PÉPIN™ FAST Series™ adjustable dumbbell comes with two micro-adjustment plates that weigh 2.5lbs each. Using these weights, you can increase the weight of each dumbbell in 5lb increments up to 125lbs. The micro-adjustment plates also allow for 2.5lb adjustments, if you don't mind the small imbalance between the two heads. Having the micro-adjustment plate inside the handle and closer to the center of gravity reduces that issue.
The minimum weight of the adjustable dumbbell is 10lbs. The maximum weight is 125lbs.
Adjusting the selected weight is super easy and satisfying. On the side rail selector rods on each dumbbell, just press the magnetic pop-pins out, slide them to your desired weight, and then press them back in to hear a click.
You can change weight very quickly -- even without the cradle, if you want to do drop sets. Just set the dumbbell down, press and slide the magnetic pop-pins, and then press them back into place.
While they may not be completely silent like fixed dumbbells, the overall design and tight tolerances allow for minimal noise.
CNC stands for "computer numerical control," a process of using computer software to control the movement and operation of machines that can cut, carve, or engrave materials.
Soon! Our engineers are currently developing a special cart that will work with both the QuickDraw™ and REP® x PÉPIN™ FAST Series™ adjustable dumbbell.
Yes, it comes with a lifetime warranty.
REP® will warranty these products from defects in material, functionality, and workmanship for the lifetime of the product. Lifetime warranty coverage ends when the product becomes unusable for reasons other than defects in material or workmanship. The warranty applies only to the original purchaser and is nontransferable.
While we've ensured the dumbbell is designed to withstand occasional drops without issue, even pro-style, fixed dumbbells can be broken with repeated drops and abuse. If you have to drop your adjustable dumbbell, we recommend dropping it as flat as possible, as edge drops will put the most stress on the dumbbell.
The lifetime warranty does not cover:
Wear and tear due to normal usage (e.g., scratches, dents, rust).
Any damage to any part resulting from abnormal/abusive use (consistent drops), negligence, lack of care, accidents (drops/dings), incorrect use and/or operation of the dumbbell as specified in the user manual by REP®.
The REP® x PÉPIN™ FAST Series™ is designed exclusively for flat storage and operation, meaning it’s optimized for use on level surfaces. Using it on an angled surfaces, trays, or racks may impact its performance and stability, leading to potential operational issues.
