Peaty's CO2 Tyre Inflator Head Only - Unique Compact Straight Line Design for Maximum Airflow & Rapid Inflation, Presta Valve Compatible Bike Tire Pump for Mountain, Road & Gravel Bikes

Doesn’t work with TPU without treaded heads. You push to inflate but the valve goes off inside the rim. Useless

I’ve used a Lezyne CO2 head for several years. It was fine, but it has the right-angle design with screw tap and you had to make sure it was in the right position before screwing in the cartridge. This Peaty’s device is a new design and is much better. I read that it puts less strain on the Presta valve. I’ve yet to use it but I’ve watched the videos. I picked a colour to match my new bike. It’s expensive I suppose, but it’s good quality and if you look after it, it should give years of service.

Does what it is advertised to do, fast inflation, fast enough to seat a tubeless MTB tyre. Nice and small. Bit expensive but a worthwhile solid bit of kit

I like the type of push-on inflators, but this one is just to expensive

Worth it, not just a gimmick. Push and inflate, simplicity. No loss of pressure, and no fiddling around

This is serious kit and very reasonably priced for such excellent build quality. A++++++++
