Basically a foam insert which wraps around your inner tube to allow the tyre to run at a lower pressure and provide a foam barrier between the tube and any puncture risk. If you get a flat it seems they also allow a ride on option albeit at a lower speed.

It's that time of year when flats increase and I think this is more for MTB and gravel sized tyres than road 28s and below.

I binned tubeless after still getting flats and having one explode from the rim in direct sunshine.

Excellent reviews and feedback on YouTube etc so I've ordered a set of 700x35/40 for my electric gravel bike which will get more use this winter.

A niche within a niche but you know it's cycling and we all want to spend money on new cycling stuff for the marginal gains :-)

This seems a brilliant idea. Anything to help prevent the curse of the flat tyre.
As a side, I've been using the Panaracer felt stuff that sticks to the inside of the tyre, really easy to fit and works great.
Top marks for this post and thanks.
Lower tyre pressure. Dose that mean more resistance therefore harder on the legs and also a fitter rider..

Yes and no. If your tyres conform to a bump (as they are softer) it's better than being rock hard and getting "fired" off the top of it. If on the smooth flat road they are squashed flat then you'll just be slower!

Science says, it doesn't make any difference.

Soft tyres with a big bump can then pinch the inner tube between the tyre casing and the rim, and give a puncture.

I once fitted some "Green Tyre" solid tyres, when I was annoyed by too many punctures. These had a thick foam core, with no inner tube. Then a friend borrowed my bike, and rode it along a rough track. It hit a bump, but didn't puncture. It just bent the wheel instead.

For road cycling, these things mean I rarely get a puncture:

1. Keep tyres pumped up hard to avoid pinch flats
2. Buy decent quality tyres (Schwalbe or Continental) and replace them if they get worn through. The tread pattern on a high pressure bicycle tyre isn't to stop aquaplaning as on a car, but when the tyre casing gets too thin, then its more likely to pick up punctures.
3. Avoid cycling through rubbish and broken glass in the gutter. On a road, I'll ride down the line that is swept clear by the nearside car tyres.
4. It took me a while to learn how to repair a puncture, so that the inner tube doesn't get snagged between the tyre bead and the rim. Before I learnt this, I would get another puncture within 50 miles.

I've been mountain biking for years and I've been plagued with punctures killing my adrenaline fuelled buzz! Discovered these Tannus armour inserts at a bike show a few months ago and they've put all the enjoyment back in my biking, I cant remember the last time I changed an inner tube! At this price I'll be stocking up for spares.

Heat bought them a while back for my ebike.
I was amazed when I switched from the Specialized puncture resistant tyres to Schwalbe Marathons - I was getting a flat every few weeks, now it's every year or so!
Well if anyone has received them and not fitted them yet.....it took me 2 1/2 hrs to fit both. A combination of cleaning up and desticking old tubeless fluid, ultra tight folding tubeless gravel tyres on tubeless ready rims and a rear with a motor ( Orbea ). Once done it was all worth it, ultra plush ride, low pressure, no spare tubes or co2 to carry balances out the extra weight from the armour and peace of mind over winter.

Science says it does make a difference.

As the additional rolling resistance (which is released as heat) comes off what would normally power the bike.

A good non pro cyclist might power a bike with about 200W on a run, but crap rolling resistance could take 20W of this.

This is only about 1% of the power in most kettles, so gives you an idea of how little heat generated can make a considerable difference.
I missed this price back up
