Silca floor pump

This will pump up tyres all day, every day, for ever

It will but given the choice I'd go for the Silca. The Rennkompressor base is…temperamental and I've found the handle works loose pretty quickly and the EVA head is far from durable*.

Given this…

But if you must have the Silca, you can get them here (I can't believe how cheap they are, I thought they were a similar price to the SKS)

Silca wins hands down.

I bet SJS stock every singly tiny little piece of it as a spare too.

*This is in a busy velodrome. In average Joe's garage it'll probably last a lifetime.
