Unlike the vinyl or rubber coated hand rims, RibGrips Handrim Covers can take a strike from sharp objects without the material peeling off.

The material is extremely resistant to tearing and separation. The material can be stretched up to 10x the designed dimensions and return to original size without wear.

For regular everyday use, we’ve found that our grip covers can be applied directly to clean raw 3/4”
diameter tubing handrims with minimal rolling/twisting.

For more aggressive use, we provide a special tacky roll-on adhesive with each order which can be applied to the cover prior to installation. This roll-on glue provides a secure hold with extremely minimal rolling/twisting.

For sport use, we have found that Gorilla brand Clear Gel Glue can be applied sparingly (dots or lines) on the clean raw 3/4” diameter hand rim tubing prior to installation for a
more permanent hold.  This permanent hold is comparable to our original over-molded design.

We suggest using the roll-on adhesive option as it allows our grip covers to be removed, washed and re-installed or replaced quickly and easily without the need to remove the hand rims from the chair.

Passive User:
No Roll-on Adhesive

Aggressive User:
Roll-on Adhesive (provided with each order)

Permanent Hold:
Gorilla Clear Gel Glue

(Note: Gorilla Glue manufactures a variety of adhesives. Due to our proprietary material, we've found Gorilla Clear Gel is the only adhesive to secure RibGrips
covers to clean raw aluminum hand rims. If you choose a permanent hold, you must remove the water soluble tacky glue by washing both the covers and hand rims before applying.) 

Not Recommended. We suggest installing RibGrips on a clean raw hand rim for best performance.

During research and development, RibGrips users found that their RibGrips Handrim Covers lasted from 12-14 months before showing significant signs of wear.

Further, aggressive users found that even after ribs became worn, the base layer of material still provided enhanced braking and propulsion.

Yes, just as you would get from any coated hand rim. Users may need to get used to applying less grip pressure when slowing and braking. Less contact and grip pressure is
required with RibGrips (compared to other coated push rims). This is due to the mechanical advantages of Ribgrips' material and design.

Excessive grip pressure may lead to some friction heat due to the inherent “grab-you-back” properties of the material.

Note: 
RibGrips were not designed to be used with gloves, but we realize they may be needed for certain obstacles. Usage of gloves with RibGrips act as soft brake pads
which will wear the rib discs down very fast.

Yes, RibGrips material is
Latex-free and has Antimicrobial protection.

RibGrips Handrim Covers are 1/4 inch wider in diameter than the typical coated handrim. This maximizes gripping surface and ergonomic feel while still allowing users to fit through standard sized doorways.

Testing and feedback from customers has shown that RibGrips work very well in light rain! However, like any typical coated hand rim, RibGrips will be slick in continuous rain.

Ribgrips are designed to self clean and resist debris build-up with regular use. Extra cleaning and. sterilization may be accomplished as follows:

Use an alcohol solution to limit microbial proliferation. We recommend using a spray bottle and misting the ribs allowing the solution to get in between the rib discs. Then wipe once clockwise and counter clockwise 360° with a damp cloth.

Use a soft plastic bristled brush along with liquid soapy water brush once or twice clockwise and counter clockwise 360°. Allow 1 to 2 minutes to dry.
