TESTED: Dynaplug® Micro Pro

Dynaplug….a license to repair!

Cue the James Bond music; I unscrewed the cap from the capsule to reveal several shiny dart like implements sitting ominously within.  

It certainly felt like a scene from a James Bond movie as I unscrewed the cap on this intriguing little device and why not, you only need to take one look at it to see what I’m talking about.

We’ve been hearing about a secret weapon on the trails, repairing punctures in style with 007 finesse. This non-lethal weapon is made by Dynaplug® and is a beautifully crafted piece of kit that comes in a range of selections, so look out punctures, your number is up!

Who are Dynaplug®?

Founded in 1991, Dynaplug® was designed as an easy-to-use solution for DIY tubeless tire repair. Dynaplug® claim that this DIY solution will make fast, permanent repairs on 98% of all tubeless punctures.

The attraction of the Dynaplug® system is that they don’t require any reaming, chemicals, adhesive or waiting time. Simply remove the puncture object and insert the repair plug. Job done!

Ever had a puncture in your car tyre? If so, you may of seen this type of process being used at your local garage to repair that tyre. It’s been around for donkeys years and is a tried and tested method to sealing holes in tyres, what Dynaplug® have done is made is sexy.

Features

The Dynaplug® Micro Pro is made from solid billet 6061 aluminum and holds as many as four insertion tubes with plugs, air stopper and micro knife. It’s also very small, I mean tiny!

The cylinder can be pushed into any space in your pack or strapped to the bike frame. It’s also very light, weighing in at only 43grams. Not even the most hardcore XC riders would really notice that. You could essentially push this into any space. We’ll just leave that there.

How It Works

Remove – Align – Push – Pull. Is pretty much all you need to do.

The Dynaplug® system is designed to seal holes that are larger than the sealant can plug itself, plus they need to be of a circular type of puncture. A split or slash and it wont work. You’ll need to use a tube as you normally would. That aside…

The scenario, if you can picture it: You’re out riding, be it on trails or the road and you happen to get a piece of stick or nail stuck into your tyre. At this stage you can do nothing, watch your tyre deflate and all that lovely tyre sealant leak out…or you can plug it and carry on with your riding.

Lucky for you, you have one of these gadgets stowed away in your pack. So let’s pull out our Dynaplug® system and get plugging!

The Test

Testing the Dynaplug® system requires a puncture. So as you can imagine this may take a while. We didn’t have the luxury or misfortune, to wait for a real puncture. So we had to go ahead and puncture a perfectly healthy tyre with a piece of metal. I can tell you, it  was an odd feeling sticking a piece of metal in an almost new $80 tyre. Oh well, all in the name of gear reviews.

Step 1

To make a repair, first start by finding the object in your tyre. Pull this object out and quickly plug the hole with the supplied Air Stopper. It’s the thing that looks like a metal dart. Once this is in the hole, you have time to prepare for the repair.

You need to plug the hole before the tyre goes completely flat, or the process will be pretty much impossible to do.  The air volume in the tyre will give you enough pressure to be able to push the plug through the casing.

Step 2

The Repair Plug is made of a fibrous viscoelastic-impregnated rubber which is fixed to a pointed brass tip. The cap of the capsule has a metal tube connected to it. This is the insertion tube. Insert one of the Repair Plugs into the insertion tube.

Step 3

Align the Repair Plug pointy end as close to the Air Stopper as possible. This next step needs to be quick because as soon as you remove the Repair Plug you will start to lose air in the tyre.

So line them up and then quickly remove the Air Stopper and push in the Repair Plug. At this point you will need some effort to make sure the Repair Plug is pushed all the way into the tyre thickness. This is done when the pointy brass tip has disappeared into the tyre.

You do need a little bit of force to get the pointy nipple through the tyre wall. There should be no nipple showing, only the fibrous plug. Pic:©Richard McGibbon

Step 4

Pull the cap away and the Repair Plug should remain in the tyre. If this has been done correctly you wont see any of the brass tip, only the sticky fibrous Repair Plug material sticking out of the tyre.

The brass head keeps the whole plug safely inside the tyre as the fibrous material spreads out and seals the puncture.

Finally, use a knife or the Dynaplug® blade to cut the plug flush with the tread. This is not essential but keeps it neat. We rode on ours for several months with it sticking out. It eventually just frays.

Conclusions

The beauty of the Dynaplug® Micro Pro is it’s absolutely tiny! There are no issues with space in your pack or even your pockets. It does what is says on the packet and it does it very well.  It’s a beautifully designed and engineered product that looks the biz!

However, with all its good looks, the Dynaplug® system only really seals puncture holes. A slash or slice and it wont work. But that said, it repairs these types of punctures perfectly. The system also pretty much permanently repairs the tyre, saving you buying another. So this saves you at least $60 – $80 straight off!

The tyre you see in this post went on for another couple of months riding, on all types of trails. From fast bike park trails with big jumps and drops to techy, rocky trails. The only reason I changed the tyre was because the tread was low. I didn’t even bother trimming the fibrous plug.

But the best part to all of this is the way your fellow riding buddies will gape in awe as you jump into action with this Bond like gadget. Cue the James Bond music….Dang de dang dang, de de de dang de dang dang, de de de…

Where To Buy

You can pick the Dynaplug® kits up from most good bike shops.

I hope what we do here at Tyres and Soles will inspire people to get out there and experience first hand, the natural wonders that surround them.

So, pump up those tyres, don your favourite boots. Grab a mate, a partner, a pet… and head out into nature. But tell us all about it when you get back.
