The Topeak Mountain TT Twin Turbo Mini-pump features a small form factor that pushes a lot more air than its diminutive size suggests thanks to the large diameter tubes and the Twin Turbo design. The compact package has a streamlined form factor that helps with cleaning it for riders that prefer to run it strapped to their frames.

Pump it up
I did have a challenge when I attempted to mount the pump on my Specialized Status. A downside to the large diameter tubes is as the fit was a no-go on my Specialized Status. The bottle mounts are set low on the frame to accommodate a water bottle, and the pump contacted the bend in the downtube near the bottom bracket. This is more an issue with clearance for accessories with this specific frame though.
The pump ended up on my Kona Honzo hardtail, which already had a Topeak bottle cage and mini tool mounted. The complete set of accessories looks sharp, and the black color matches well with the all-black motif.
My favorite mini-pumps usually feature an extended valve on a hose, as I seem to be pump challenged, and have bent and damaged valve stems while pumping vigorously on the side of the trail. The large-diameter tubing adds to the ergonomics of using the pump and makes this less of an issue as I’m able to easily place a hand on the head to brace it with the other on the end of the pump.
On the Trail
Mini pumps are never that fun to use. Let’s face it, no rational rider would ever choose a mini-pump over a floor pump unless you’re stuck on the side of the trail. I don’t like carrying C02s due to the material waste, so I always carry a mini pump, plugs, and a tube as my insurance policy. In use, the pump’s ability to push air in both directions of its stroke combined with the large volume tubes cuts down the number of strokes needed to get back on the trail. The larger volume tubes also add to its ergonomics as well.
