The folks from Slime recently sent some products for us to try — a “care package”, if you will, of goodies to keep us safe on the road.
The tubes went in without a hitch — and they’re pre-filled with that lovely green goop, so there is no mess to speak of. I installed these tubes on my dedicated commuter bike which runs 26″ x 1.25″ slicks. Although I haven’t intentionally ridden over anything to test the puncture resistance (and subsequent sealing) properties of the tubes, I do go through some rough areas where there is a lot of broken glass and bits of metal in the road, and I haven’t gotten a flat yet!
I also got a bottle of Slime tube sealant – enough to fill two fat 26″ MTB tubes. I treated my “Bike Snob Disapproved” Patriot MTB to this treatment, since I depend on this bike to get my son to school on time.
Getting the Slime sealant into the tubes was fairly easy — the sealant packaging even comes with a valve core remover! I did have a problem once I got the valve cores back in, though. I discovered that the cores “goop up” and prevent the tire from reinflating unless they are cleaned. To prevent this from happening, clean the inside of the rubber valve with a cotton swab before you reinsert the valve core. Luckily, I have a drawer at home full of punctured tubes waiting to be patched, so I just salvaged clean cores from a couple of them and was on my way in no time.
Again, I haven’t intentionally tried to pop one of these self-treated tubes either…but I just might one of the these days to see how the Slime works! I have noticed, though, that on these and the pre-filled tubes that I don’t have to add air to my tires as often, and I have also noticed that there is no difference in “feel” as the tires roll along the ground. I was expecting some wobbling or something, but apparently the Slime coats the tube evenly with no puddling. It pays to ride around the block a couple times just after you fill your tubes to help distribute the goop around the inside of the tubes.
Finally, I have used the digital tire gauge a few times — the tip and digital display light up for nighttime pressure checks! The gauge appears fairly accurate…the readings match both my tire pump gauge and a traditional “sliding stick” tire gauge. The Slime gauge fits nicely in my hand and has a rubbery gripping surface. Best of all, it has an auto shutoff feature so I don’t burn through the batteries!
These products are certainly worth a try, even for added peace of mind. I’ll report back in a few weeks after I devise some terrifying ways of really testing the puncture-sealing abilities of these products! Back to the Bikecommuters.com Secret Laboratory — surely there’s a box of thumbtacks in there that I could sprinkle on the street?
