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 552 Adjustable Dumbbells, CORE Fitness, Peloton, JaxJox, MX Select, Weider, and many others. 

For Bowflex 1090s, the Hyperbell works with models purchased before 2010. Newer models of the Bowflex 1090s have a thicker handle dimension of 2" and will not fit.

HYPERBELL does not work with Nuobell, PowerBlock, Neoprene (rubber) dumbbells, NordicTrack (blue version) or FitRx.

What is the difference between CrossGrips and RYZE-UPS? 
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 most door frames. CrossGrips is designed to be compatible with top door molding heights between 2 to 4 inches and inside door frame widths ranging from 4.5 to 7.5 inches. RYZE-UPS are adjustable and can fit doors that are taller/wider. 

Can I take CrossGrips/RYZE-UPS on a plane?
Absolutely. CrossGrips/RYZE-UPS 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.

Can I return CrossGrips/RYZE-UPS if they don’t fit my door?
Yes, you can return them if they don't fit. Measure your door before you place an order and you won't have any problem.
