SLIMEPRO Tubeless Bicycle Sealant Review
Slimepro Tubeless Sealant is claimed to instantly seal punctures up to 1/8” while weighing in at just 1g per mL. Slimepro also contains rust and corrosion inhibitors so that, unlike several other tire sealants, there is no damage to the inside of the rim.
On their website, Slime states that “after extensively testing other tubeless sealant products and identifying key customer complaints, Slime gathered a team of racing professionals to create a superior tubeless sealant product.
The result is Slimepro Tubeless Sealant, an advanced formula that outperforms the competition.”
I happen to be one of those testers and I must admit that this stuff really works better than advertised!
WHATS IN THE PACKAGE:
Included is a 16 ounce bottle of Slimepro Tubeless Sealant, a cap to reseal the bottle, a measuring cup with indicators for 1.5oz, 2oz, and 3oz, a funnel cap and 2 ends for pouring Slime into a Presta or Schrader valve. Also included is a detailed instruction sheet.
INSTALLATION OBSERVATIONS:
There are certain tubeless tires will fight you as you as you try inflate them. When testing IRC Road Tubeless, I was able to seal the tires using a floor pump. With Hutchinson’s, I had to resort to an air compressor. (A CO2 cartridge would have worked as well, but I didn’t feel like wasting one.) This is the hardest part of the whole process. The easiest parts of the process were (a) measuring out 1.5 ounces, (b) adding the Slimepro to the tire and (c) cleaning everything up with two paper towels!
Once the tire is mounted, lay the wheel sideways on a workbench and spin the wheel slowly so that the Slime sealant has a chance to work its way between the rim and tire. Do this for both sides.
HOW DID SLIMEPRO PERFORM?
Recently, I have been testing several ‘to be released’ tubeless road tires. During 1,800 miles of testing, I had 2 flats on that rear tire. The first flat was at 700 miles when I ran over a small sharp piece of metal which caused a 1/4″ slice on the outside and a 1/8″ slash on the inside. The Slimepro sealed it quickly. Just to make sure that the cut was fully sealed, I stopped to shake and rotate the tire. After a minute, I topped off the tire with a partial CO2. The Slime that remained held up through to the second flat at about 1,500 miles. The remaining Slime easily plugged this leak as well. When I got back to the shop, I added a little more Slime to the tire.
At 1,800 miles, the cords were starting to show through the tread, so off it came.
CLEANUP
After removing the tire from the rim, I was surprised how quickly and easily Slimepro cleaned up. I placed two paper towels inside the tire to soak up the Slime and then placed the tire in a bag to send back to the manufacturer. For the rim, I used two clean paper towels to completely clean the Slime from the inside of the rim. Lastly, I let the wheel sit for a few minutes, and then used a bottle brush to clean up any remaining Slimepro from inside the lip that seals the tire to the rim. The pictures below show the rim after this quick cleaning.
WHAT ELSE WILL SLIMEPRO DO FOR ME?
Slimepro also contains rust and corrosion inhibitors. I have been using Slimepro for over 2 years on various wheel sets and so far, I have not seen any indication of rust or corrosion from inside of the wheels.
HOW MUCH SLIME DO I USE?
Slimepro Tubeless Sealant weighs in at just 1g per mL, and can easily be measured out using the included measuring cap.
For my 700×23 road tires, I started out using the recommended 1.5 ounces. After testing Slimepro, I believe that a single ounce is probably good enough for a 700×21/700×23.
INSTALLATION SECRETS – WHAT ELSE DO I NEED TO KNOW?
- Wipe a little sealant on the bead of the tire before mounting onto the wheel.
- Inflate the tubeless tires using a high volume/pressure pump. It is the initial blast of air that starts the bead to seal onto the rim wall.
- If the tire is losing air, it is probably escaping from around the bead. Dip the wheel under water to easily find these leaks via the bubbles.
- If the tire holds air for a day then goes flat, pump it back up and turn the wheel allowing the Slime to recoat the inside of the tire. Shake the tire to re-coat the inside. Then spin the wheel to evenly coat the entire inside.
- If it is still losing air, add another 0.5 to 1 ounce of Slime to the inside of the tire.
- If it is still losing air, then there is usually a piece of debris on the bead or the rim preventing a full seal.
- Do not fill above the tire manufacturers recommended tire pressure range.
OVERALL SUMMARY:
I was very impressed with the quality and ease of use of this product.
This product worked as advertised and performed its function efficiently. I highly recommend this product!
I have always enjoyed bicycling and, through a series of coincidences, became a Bicycle Industry Consultant and Product Tester. I test prototype products for companies and have published only off the shelf production products on biketestreviews.com.
