Another HPX fan. The Zephal "Classic" looks like the old long discontinued HP but is in fact an HPX. (Both the old HPs from the early '70s on and the HPXs are/were excellent pumps. The HPX has a frame fit head, the HP requires a pump peg or the umbrella-like fitting. HPXs have a lockout of the spring in the handle that keeps the pump secure on the bike. With the lock-out, you do not have to pump against that spring. The HPs were the (slightly) more robust pump; in part just because they were simpler. Both pumps are some of the best bike pumps ever made. When I raced in the '70s, I owned 2-3 bikes, all on sew-ups, and used only the pumps on my bikes. I only replaced them due to: losing or having them borrowed and cars running over them. (One survived and I used it for many more years,)

There are other frame pumps out there but I see little reason to stray from the Zephals. There is one real drawback however. If you ride with others, your Zephal will see use inflating tires that are not yours (when their inflation devices fail or expire). You will not see the return favor. One of my HPXs died on a gravel ride when there were more than 20 flats among the dozen of us. I got tired of pumping (for the flats of others; I had none) and the pump came back to me busted. It still pumped air but the spring in the handle was messed up so I couldn't carry it on the bike.
