For this review, we test the DYNAPLUG® Micro Pro Tubeless Bicycle Tire Repair Kit.

HOW WELL DID IT WORK?

Seems like if you want to get a flat, it never happens. Prior to the test, I put on a new $90 tubeless tire and put DYNAPLUG Micro Pro - Tubeless Bicycle Tire Repair Kit

DYNAPLUG Micro Pro - Tubeless Bicycle Tire Repair Kit

around 600 miles on it, not a single flat or cut. In most cases, this is a good thing, but for this test not so much. Not wanting to push a nail through a $90 tire, I asked several friends who run tubeless if they had any old & worn ones. The same answer came back “no, I’m running lightweight clinchers now.” Not a worn out road tubeless in Southern California! Looks like most roadies have gone back to clinchers.

Finally giving up on either getting a flat on my road tubeless or finding a worn out one, I asked a friend who races MTB’s for the next best thing – a worn out MTB tire. I was in luck. The day before, he had run over some kind of sharp rock that put a small slice in his 27.5 tire. This slice went all the way through. He said he had no luck with using sealant. Since the tire was pretty worn, he decided to dump it and put on a new one. I drove right over and picked it up. Perfect!

Another good friend of mine works at a local bike shop and in my opinion, one of the top mechanics in Southern California. He also races MTB and runs 27.5 wheels. Perfect! DYNAPLUG Micro Pro - Tubeless Bicycle Tire Repair Kit

During his lunch break, we took off his wheel and pulled his tire. Full of sealant, we carefully layed it aside. The first thing we did was to add some sealant to the old tire. Using one of the name-brand tubeless tire sealants, we remounted the tire and inflated it. Confirmed – the slit was too large for the sealant to stop the leak. All that happened was that the sealant continued to squirt out the slit and all over the floor. Good mechanics know A LOT of tricks and he tried them all to no avail. We could not get the leak to seal. We removed the tire and poured the remaining sealant back into a small bottle for later use.

Next, out came the Dynaplug®. Since bicycle tires are not that thick at the tread, the small barrel of the DYNAPLUG Micro Pro - Tubeless Bicycle Tire Repair Kit

Dynaplug® holder is perfectly sized to create enough force to push the Dynaplug all the way through the hole. Pumping up the tire, it still leaked, but this time a lot less air was coming out. Turns out the slit was too large for one Dynaplug®. Using the supplied tools, we cleaned out the hole, then used a second Dynaplug®, inserting it right next to the first one. Pumping the tire up to 35psi, no leak! We then upped the ante to 45psi – no leak! Up to 60psi – no leak. Good enough for us!

WHAT MAKES IT WORK?

The Dynaplug® Micro Pro Tubeless Bicycle Tire Repair Kit is composed of a billet aluminum housing and a DYNAPLUG Micro Pro - Tubeless Bicycle Tire Repair Kit removable stainless steel insertion tube (to hold the repair plug). This well thought-out kit is STRONG and WELL BUILT and includes 2 insertion tubes, 5 tubeless tire repair plugs, 1 Knife, 1 clearing attachment and 1 pipe cleaner. During a repair, you will use most if not all of these during a repair.The “plug” is the whole key to what makes this work so well. It is made of a proprietary rubber impregnated cord mounted to a pointed brass tip which will seal most small holes that sealant can’t. If the hole is too large, just insert another plug.

Inflation Note: For Bicyclists, tires are low enough volume that all you need to inflate the tire is a single CO2 cartridge. For anything with more volume, like a car or truck tire, you will need an inflation kit like the one pictured here from Dynaplug®. It measures 4.75”x6”x2” and small enough for any car trunk. For a motorcycle, space is at a premium so choose a smaller inflator that you can pack in your saddle bag or rear seat cowl if you have a sport bike. There’s plenty of inflator options.

WHAT WE LIKE ABOUT DYNAPLUG®

The first thing we did was to read through the straight forward and easy to follow directions. Our repair was really as easy as “push-pull”.

What we like about this repair kit is

It repairs tubeless tires when sealant can’t
Everything needed is stored in the handle for easy access
Strong all-metal quality construction
You repair the tire without needing to remove it
Simple – in fact super simple to use
The plug’s rubber impregnated cord bonds to the rubber of the tire which means this is a long lasting repair

WHAT WILL IT ACTUALLY SEAL?

Independent testing provided by Dynaplug® showed quick and easy repair of a punctured car tire that was pierced by a 3½” 16D (penny) nail. For those that don’t know, a 16D nail has a pretty large shank diameter of 0.165” – which is a little smaller than 1/8”! The nail was extracted from the car tire and the puncture was repaired with a Dynaplug® repair plug. The tire was then run at 90 mph (150km/h) without failure! DYNAPLUG Micro Pro - Tubeless Bicycle Tire Repair Kit

Nails and screws frequently end up in car tires (Google ‘nail in tire’), but cyclists don’t usually run over 16d penny nails. More common for bicycle flat tires are glass shards as well as those pesky little pieces of wire from exploded steel belted radial tires which seem to frequent the roads of Southern California. I know that for my road bike, my last 6 flats have been all been from those little pieces of wire.

So, for both road and mountain bikes, I recommend sealant plus carry along a Dynaplug®. The sealant will stop those leaks caused by radial tire wires and the Dynaplug® will repair larger holes and cuts caused by glass or sharp rocks.

IS IT WORTH THE MONEY?

This was not a long-term test which I usually like to do. It’s unknown that if the rubber impregnated cord of the Dynaplug® will dry out sitting in your under-seat bike bag. As insurance, I would put the Dynaplug® into a plastic zip-lock bag to keep any air from potentially drying out the cords.

Since bicycle tires have a fairly short life, I believe that the Dynaplug® will last the entire life of the tire. I know CAT-1 racers (both road and MTB) that put on so many miles that they wear out tires in a month. For the rest of us, it might take a little longer. Bicycle tires by definition use fairly soft rubber which makes the Dynaplug® a perfect solution for cyclists.

Yes, I recommend Dynaplug® as a great tool to keep you on the road instead of the roadside repairing tires or worse, waiting for your better half to pick you up in the car.
