I used to have a mini pump mounted on all my bikes so I wouldn’t get caught out by not remembering to carry one. This proved to be a false sense of security when one of them failed after fixing a flat on a trail. Another rider happened along and lent me her Tattico pump. It was a gem. She said she’d researched pumps and that one was recommended.

I found when researching it myself later that cheaper pumps often fail because the o-rings/seals either just fail over time or they fail under the heat caused by pumping. I think the one that let me down failed from heat. It was almost hot to the touch. So I tested all of my pumps and threw away most of them. The ones that still were OK were the Topeaks. I kept those and left them on a couple of bikes, but I also bought a couple of Tattico Silcas to keep with the gear I use for all rides. They fit in the bottle-cage mounts that were already on my existing bikes and I bought some extra mounts that I use on new bikes.
