I use the Topeak RaceRocket HP on my road bike and the RaceRocket MT on my mountain bike. What stands out with both is how much pumping power they pack into such small bodies. They’re easy to carry and handy to have along for a ride.
RaceRocket HP for the road bike
The HP is the one I carry on my road bike. Topeak designed it with a narrow barrel for higher pressures and lists a maximum capacity of 160 psi. That’s the pump’s rating. Use the pressure appropriate for your tyres and rims.

RaceRocket MT for the mountain bike
The MT is the one I take on mountain bike rides. Its wider barrel moves more air per stroke, which suits the larger volume of mountain bike tyres. Topeak lists a maximum capacity of 90 psi.

Which one would I carry?
I’d stick with the HP for my road bike and the MT for my mountain bike. Both have an extendable hose and fit Presta and Schrader valves. Of the pumps I looked at, these were the best I found for my bikes. I’d happily carry either on the bike it suits.
