The Golden Boy, the SKS I have is called the Airbase Pro. It is silver with a cast aluminum base and has a presta valve only head. Apparently SKS considers this a track pump or suitable for bike shop duty, and has provisions for screwing it directly into the floor as a permanent fixture. The air chamber is teardrop shaped to hide an internal tube for the top mounted air gauge. The Park pump is good, but this one is seriously better. The Serfas pump is good as well, but does not match the SKS in performance. Honestly, I have used dozens of pumps, many of them freebees given to me by sales reps, and I kept going back to the Silca. The SKS was a prize for my competitive prowess (uh-huh, lol) and I just had no need for it because the Silca has been bombproof. The closest to this I have come was a pump given to me by Giant at the same time I acquired the SKS. The pump itself was excellent, and the double walled construction came in handy at the shop when a large dent found its way into it, without affecting the internal tube where the compression took place. The pump head on the Giant was no different than every other brand, and it was less than satisfactory for me. I believe the Rennkompressor is a consumer based product, but being SKS it is probably superior to its competitors. Their fenders are exactly the same way, and I have also recently found that the tire levers included with their multitool, which is exceptionally clever, are exceptionally excellent. Honestly, I am very impressed with their goods. I also have their sweet seat pack that is quick release that was won in the same event. If you remember the Presto bags, this takes the evolution a couple of steps further and the thing is, again, excellent. I'm not a fan of German stuff as I burnt out on them years ago, but SKS is impressive.
