If you’re carrying a pack then generally you might as well carry a proper pump not a stupid wee roadie’s mini pump- the difference in size and weight isn’t really much but the difference in function is enormous.
I always recommend the Evolution, which you can buy as M:Parts, Truflo, and some others… It’s basically just like a Mountain Morph, except cheaper and more durable (ie, the foot doesn’t fall off all the blimmin time). Once you’ve used one of these folding pumps with a hose, you need a good reason to go back.
Lezyne as ever are very pretty, and very well made, and not very well thought out.
