Below are the steps we use in-house to achieve the best results for temporary and permanent bonding of our covers to clean, raw, 3/4"
circular diameter tubing handrims. #4, #6 and #7 are important steps that will help with first time insulation issues should any occur. 
Verify hand rim tubing is 3/4" circular diameter (or close to).  Our RibGrips (RG) covers are NOT designed to fit "Oval" or "U" shaped
hand rims (like Surge & Natural Fit) OR be installed over pre-coated hand rims. 

Verify each hand rim's outer diameter in inches by measuring from outside to outside across each handrim's center.  This is the number we
need to correctly make your order.

After verification, clean each hand rim thoroughly with isopropyl alcohol to remove ALL oils and contaminants.  The cleaner the better!

Before installation, lightly pre-stretch each RG cover by hand (like a rubber band) to make installation easier. 

Our covers were designed to be easy to remove for cleaning or replacement without disassembly of the wheels which is why we include a
non-permanent, roll-on tack glue.  If using our roll-on tack glue, apply to the inside of each cover from edge to edge along the entire
circumference.  Then, let the cover sit for 10 minutes prior to installation to allow the tack glue to set-up and get tacky.  After 10
minutes.

it's time to install.

For 1-person installation, it's suggested to start at 12 o'clock and work around the circumference of the hand rim in a clockwise
or counter-clockwise direction until completely installed. This technique might create some distortion of the cover which may
require the installer to adjust the cover in specific areas for a better fit; just pull or stretch (like a rubber band) the cover away and
reposition as needed.

Once a cover is installed, allow up to 45 minutes for the tack glue to set-up further.  The tack glue will NEVER fully cure as it is designed
to be non-permanent, but it should provide adequate hold for every-day use.

Sections of a newly installed cover may peel away from the hand rim. If you encounter this, stretch the section of the cover that peeled away
(like a rubber band), apply more tack glue inside then reposition on the hand rim. This typically solves the peel away effect. If covers still
feel loose or slightly roll, reapply the tacky glue. Allow at least 45 minutes between coats.  The thicker and gummier glue build gives a
firmer adhere to the hand rim.

For permanent hold, we have found that Gorilla Glue Clear Gel (GGCG)
is the best solution. 
Assuming the inside of the covers and hand rims are clean of oils, contaminants and roll-on tacky glue, simply apply lines of GGCG to the
inside of each cover and then immediately install the covers to each hand rim following the 1-person installation guide above. 
You do NOT need to completely cover the inside of each cover with GGCG as the bond it creates between the cover and handrim IS permanent.  

BE ADVISED that this glue is great for bonding use, but makes it extremely difficult to remove worn covers from hand rims for future replacement
and may leave residue.

Note:
Gorilla Glue manufactures a variety of adhesives. Due to our proprietary material, we've found Gorilla Clear Gel (has a green cap) 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.
