In the 1920's SILCA revolutionized roadside inflation with the creation of the Impero Frame Fit Pump. These early pumps used the revolutionary material 'Duraliminium' (2000 series aluminum) to replace steel. Within a few years SILCA pumps could be found on the bicycles of more than 80% of the professional peloton which was then still fully self supported. Over the next 70 years the Impero would be the most widely used frame pump in the world, introducing further technology advancements, first changing the barrel to Celluloid and later moving the handle and head to Plastic in the 1960's.

For 2015 we are thrilled to introduce Impero Ultimate, the merging of high tech modern materials and manufacturing with the full aluminum construction and durability that was a hallmark of the original Impero.

Impero Ultimate features a high tech head gasket with unique 2-stage seal to provide ultimate sealing and holding even when compared to lever chuck designs. Solid aluminum head with brass check valve ensures a lifetime of flawless use, and fully aluminum barrel, handle and piston rod result in a pump that is both competitive in weight with plastic designs while being significantly stronger, smoother and more durable.

Unique FlexWing Silicone bumpers on the head and handle tip are designed to handle tubing diameters from 1" (25mm) to 2.5" (64mm) using a unique flexible outer wing which adjusts under pressure. An additional Silicone bumper on the main barrel protects paint, eliminates vibrations and noise, and also acts as a compression lock against the pump handle to keep it from moving unless you want it to.

Impero Ultimate is Manufactured in the USA using Alcoa Aluminum extrusions and bar stock. Impero uses a 19mm diameter leather piston custom manufactured by the same supplier in Milan who has supplied SILCA leather since 1947, and the brass check valve is a modified version of the check valve used in the SuperPista Ultimate.

Impero Ultimate represents the Ultimate in design, functionality, security and longevity.

Castelli Cafe - Fitting Guide

Castelli is sized against the rider's physical dimensions the size data in the size guide is the rider size, not the garment size. Castelli garment size is optimised for intended function, So for example an Aero Jersey or Speed Suit are designed to be extremely close fitting, using the material stretch to fit the rider's torso. A race jersey laid on top of a non race jersey of the same size may appear 5cm narrower and not as long - this is intentional as the garment fabrics are designed to stretch to accommodate the riders body shape creating a very close aerodynamic race fit. Never measure old kit to get your Castelli size always measure yourself.

Shoe covers are designed to fit snuggly over road racing shoes only (unless otherwise stated). If your shoes are to the upper end of the size designation and have bulky buckles you should consider the next size up.


1. Snug Fitting; On the bike your jersey or jacket fits snuggly. When riding you don't hear or feel any fabric flapping the close fit helps the capillary action of the fabric to draw moisture from the skin helping you feel drier and more comfortable.


2. Rider Positioning; Fit Off the bike your Castelli jersey or jacket might feel tight across the chest and a little short at the front. This is because the jersey is designed to fit the rider in the riding position. On the bike the fit is prefect with no bunching at the waist and no sagging over the chest. Please keep this in mind when trying on new garments.


3. Fabric Engineering; We use fabrics specifically engineered to wick moisture from the skin or between fabrics, We have created a apparel range that starts with wicking base layers passes through jerseys and onto jackets and shell fabrics. Every element is designed to optimize its specific application - wicking, cooling, thermo regulation, breathability and protection. In order for this to work the fit has to be snug (but never tight)


4. Aerodynamics; The other important aspect of close fitting garments is the aerodynamic advantage they provide. We work closely with professional riders from the Cannondale Team and in wind tunnels to optimise the fit, (again in the important riding position) sleeves are articulated forward to eliminate wrinkles and provide maximum body contact. As an example of our obsession we created the Gabba range of products based around the fit of a race jersey Gabba fits snuggly but provides ultimate weather protection its a key race piece for poor weather conditions allowing athletes to gain an aero advantage over rivals in rain capes.


5. Bib-short Fit; Bib-shorts fit is just as important as a jersey in providing performance - enhancing features such as aerodynamics and muscle support, as well as protecting your bottom from hours spent in the saddle. Bib-shorts should fit tightly enough to support critical leg muscles through compression without inhibiting movement and constricting blood flow. Using a combination of fabrics allows us to fine tune each material's characteristics to optimize fit and performance.
