Hi,

This pump has been tested on 29" tyres with widths upwards of 2.4" tyres from different brands onto a couple of different rims.

I would agree in saying that the base pump part of this is for higher pressures, though nothing is stated on Lezyne's site. Either way, it happily seated knobbly tyres but its narrow main pump does mean it takes a little while to get fatter tyres up to pressure. Although I can't confidently say as it wasn't tested with such, but I imagine it would be more efficient with thinner road tyres.

Thanks for the comment!

I've got an old version of this pump without the secondary chamber and it is very much a road bike pump, designed for higher pressures.

Was this tested on road bike tyres with a variety of rims and tyres? Being in the off.road section, it doesn't seem so?

I too am terrified when flicking the switch on my topeak turbibooster X, I don't like to be around because of the VERY loud noise when the bead seats. I try and be in a different room by the time it booms.

I have never inflated with sealent inside, far too risky.

After many unsuccessful attempts, and getting quite warm and sweaty repeatedly pressurising the turbibooster I found that spending a bit of time and effort pulling the beads as far out of the well as I can helps, I have not had to use my swlabe soapy stuff yet because of this discovery, with my 3inch tyres.
