Endurance bibs and shorts take away discomfort, leaving you to fully enjoy the pleasure of a nice long ride on aboard your bike. All of Castelli's best comfort is put to good use in the construction of Endurance shorts and bibs. So much so that there is not much that can be done to make them better. The seatpad is the race proven Progetto X2 Air- now with a modified shape and perforations in the foam layer to improve airflow. The new pad keeps the rider cooler, drier and more comfortable all round. The leg grippers are single-layer engineered Giro3, providing comfortable grip with a clean cut aerodynamic edge.
    Ride to your heart's content - with these shorts on you really won't have to stop 'til you get enough!

    Castelli Endurance features:

    • The durable Action Micro fabric is form-fitting, soft on the skin yet abrasion resistant, and Prosecco treated to promote speedier sweat evaporation.
    • Energia Micro fabric at the sides supports muscles without constriction. It's ribbed surface aids with aerodynamics.
    • 4-needle flat-lock stitched seams.

      Tested by the Garmin Sharp team, the Progetto X2 seat chamois, had more than 500,000 kilometers of testing under it's belt before it first reached the market. Made with 10 separate components, and 12 different phases in the manufacturing process, the X2 Progetto has been undergoing a process of constant refinement now for some 4 years.

      Scott Mares from says:

      "The company rocks customer service and so do the shorts. I wanted to see if Willy Wonka was back in the back working with these guys because this short is the 'All Day Gobstopper' of the short world. Get a pair and they will become your favorite short."

      Fabric helps set the Castelli Endurance bib apart

      Castelli Energia FabricCastelli Endurance bibs and shorts feature Castelli's proprietary Energia and Action fabrics.
      Energia is a Power Lycra with horizontal stretch that supports the muscles and aids in recovery. LycraPower® has been scientifically proven to:

    • Reduce muscle vibration, greatly reducing muscular fatigue - enabling a higher level of performance for longer periods, relative to unstabilized muscles
    • Improves cardiovascular efficiency - by increasing blood flow to the heart and reducing the production of lactic acid in muscle tissue.
    • Aids in the recovery of damaged muscles by reducing swelling, and increasing oxygen flow to area of injury.

      Energia fabric also has a ribbed knit surface that aids with aerodynamics. Like a golf ball, irregular surface technology improves aerodynamics and is used in cycling clothing to help riders slice through the wind.

      Action fabric is a 210 gram microdenier PowerLycra with an 80% Nylon and 20% Lycra blend. The strength of Action fabric lies in it's soft feel against the skin, providing complete comfort, combined with it's high abrasion resistance and the durability this provides. This is particularly useful in the saddle contact area of the short.

      This Action Micro fabric on the Endurance Bibshort has been Prosecco treated to promote speedier evaporation of moisture and keep you dry and comfortable. Prosecco hydrophylic treatment does this by spreading moisture over a larger surface area within the fabric, drawing perspiration away from the body and allowing it to evaporate more quickly.

      All this is held together with 4-needle flatlock stitching, further increasing the comfort and durability of the short. Let the Endurance bibshort help you hold it together - it will undoubtedly increase your own comfort and durability for many a ride to come!


      The Progetto X2 Air Chamois from Castelli

      Redesigned for 2012, to make you even more comfortable, the Progetto X2 Air chamois, from Castelli is now cooler and drier. This has been achieved by adding perforations to the comfort layer of the pad, allowing improved ventilation and moisture evaporation. Also, thanks to feedback from professional riders, the shape of the pad has been altered slightly to better fit to the rider shape in the saddle area.

      Small steps for the Castelli Technical Team, but a major leap for the comfort of cycling mankind!


      Giro3 Single-Layer Engineered Leg Grippers
      on the Castelli Endurance Short

      Instead of stitching a silicone leg elastic band to the leg of the short, Castelli knit the grip material directly into a 2 inch deep single layer of fabric at the base of the leg. This is then 4-needle flat-lock stitched to the hem for added comfort, with durability.

      This 2 inch gripper band has a more gentle compression than traditional leg grippers, whilst securely holding the short in place. This means that it will not bind, or leave that crease you can get on your legs after hours of wear.

      The bottom of the leg has a clean-cut edge that will lie flat against the skin, for aerodynamic benefit. This style of leg gripper will still works well with your leg warmers on those cooler days.

      Contrasting Castelli wordmarks are sublimated onto the gripper, and reflective tabs are included at the rear of each leg.
