Servus!
Topeak makes good stuff. I have used their floor pumps and the SmartHead attatchment is tops. Good saddle bags and micro tools as well.
I actually got "shot" by my zefal mt. mini. Stuck it on, wrestled, pumped up the tire to a modest pressure, and the back pressure blew the plunger out of the pump body (somehow circumnavigating the threads!) and hit me in the ankle. Leaving me to jury-rig the pump and try the whole process again.
Ahh, how technology enriches our lives.....
