Which dumbbells will HYPERBELL work with? 

HYPERBELL works with almost all regular and adjustable dumbbells. However, there are some limitations. The length of the dumbbell handle needs to be at least 4.5" long. Most dumbbell handles are approximately 6.0" long. The diameter of the dumbbell handle needs to be less than 1.5" at its thickest point.  The foam insert inside the HYPERBELL will contour to both straight and curved dumbbell handles. 

HYPERBELL works great with hex dumbbells, Bowflex SelectTech Adjustable Dumbbells (552 and 1090), CORE Fitness, Peloton, JaxJox, MX Select, Weider, and many others. 

HYPERBELL does not work with PowerBlock Dumbbells or Nuobell.

What is the difference between CrossGrips and RYZE-UPS? 
For a chart that shows all the differences, go to the CrossGrips or RYZE-UPS page and click on the drop down button called "RYZE-UPS and CrossGrips Comparison". In short, CrossGrips is made with a stainless steel frame and doubles as push-up handles. RYZE-UPS are adjustable, fit even more doors (wider/taller), and have a rotating handle. 

How strong are CrossGrips?
Unlike other pull-up bars, CrossGrips use the molding on the front and back of the door. This makes them incredibly strong and allows them to hold up to 250 lbs of weight.

Will CrossGrips/RYZE-UPS fit on my door?
CrossGrips and RYZE-UPS are built to adjust and fit on almost any door. RYZE-UPS are adjustable and can fit doors that are taller/wider. To be sure that they will fit on your door, see the diagram on the product page for more details.

Can I take CrossGrips/RYZE-UPS on a plane?
Absolutely. CrossGrips are TSA friendly. Depending on the airport you may have to take them out of your carry-on (just like a laptop) but you will have no issues after that.
