Let's offroad / mountain bike / mtb / ride dirt

silca tattico, never used it myself but @leggy_blonde used mine twice, I think it works

Are you carrying in a backpack? Attached to the frame? In a pocket?

As I put mine in a Camelbak I use one of these:

Easy to fill larger volume tyres and acts like a track pump so you’re pushing into the ground

Old version of this. https://ride.lezyne.com/collections/hand-pumps-high-volume-trail/products/1-mp-alldr-v2m04

Nothing fancy. Works fine.

Works well and lasts for years and years, no matter how many people borrow it off me

I paid with my own cold hard cash. https://www.topeak.com/global/en/products/mini-pumps/1083-mountain-tt-twin-turbo

I've used most pumps, and thrown most lezyne ones in the bin. This is just better.
