I read the lezyne was best. But all the ones I bid on on ebay went for to much. I wasn’t willing to spend a lot. I bought a topeak rocket race master blaster.
Fit’s in my pocket, lives in my pocket I should say.
Bigger would be better for pumping tyres up, but I wouldn’t be able to keep it with me then.
Screw on fitting, all the push on ones I have had have been crap, some have only pumped a couple of tyres up before the rubber had died.
Does Presta and schrader.
If I lost it I would get another and probably be prepared to pay full price. I have had it 5 years this year and it’s not showing any signs of letting me down.
