The name Silca is synonymous with high end frame pumps and the Impero Ultimate II is no exception. It's the last of a dying breed of full length frame pumps as everyone sizes down to little clip on pocket pumps. Clearly it's the classier alternative for your rando or gravel bike. It is a better option for those of you running higher volume tires due to its larger cylinder. If you're real fancy you can paint match it to your bike.
The Impero Ultimate is Presta compatible.
Depending on where you'd like to put it you'll have to measure the space between the two tubes or pump peg and tube to determine which length pump to get.
Here are the length ranges each pump will wedge between:
Small- 440-490mm
Medium- 490-540mm
Large- 540-590mm
X-Large- 590-640mm
Have a Romanceur and want to run an Impero Ultimate on your pump peg behind the seat tube? Here's what size to get for each frame size:
