Plug for 'Dynaplug'
I recently made a purchase I am so happy about I though I needed to share with NoBMoB:
Anyone who has read my blogs knows a puncture ruins my races. I’m absolutely crap at getting a tube in and getting back on the bike. My usual process is I stop and turn the bike upside down then rotate the wheel so the hole is at the bottom and hold my finger over it in the hope the sealant will block it.
After a minute or so I can assess if this will work or whether I need to get a tube in. If the sealant works it is a temporary fix. If I need the tube in that’s when I break into a sweat as I know I’m in for considerable delay…
Firstly I always find my valve is glued in by sealant so need to search for a rock to bash it out. There are many people with strong hands who can pop a tyre on and off a rim without tyre leavers - not me! Once I finally get the tyre back on it’s gas time and then pack up all my crap before heading off. The usual delay is just under 15 mins.
A few months ago I received an email from Pushy’s advertising Dynaplug which is a system similar to what they use to repair punctures in car tyres. You basically push a gooyey rubber thing into the hole using a tool then when you pull it back out it leaves the hole blocked and is a permanent fix.
I looked at some reviews on YouTube and decided this would be ideal for me and has the added benefit of no longer needing to carry spare tubes. When I do the point to point enduro races like the recent Highland Fling I carry 2 spare 29” tubes plus enough gas to fill them both to say 35psi. All of that is weight plus takes up valuable pocket space or frame space when you also need to be carrying food and first aid kit.
So I did The Fling without any spares but deep down had the worry that if I did have a puncture would the system work like advertised?
Finally yesterday I was early into my training ride when I heard sealant spraying from my rear tyre. Within 1 minute I had the hole repaired and was riding again and only lost 2-3 psi so no need to use a gas bottle once the repair was done.
No more tubes for me!
