Castelli BTW Speed SuitCreated for racing, the Castelli BTW Speed Suit is their most refined, aero suit yet. Faster than the already fast San Remo suit, this is best used when you're going all-in, forging the day's break or sprinting for the win.Taking its name from a phrase coined by fast-jet military test pilots - (we'll let you research that one) - the BTW Speed Suit has been created purely in the pursuit of speed. Castelli utilised CFD analysis, 3D test mannequins, fabric research and testing, numerous wind tunnel tests, and real-world WorldTour riding, resulting in their most aero suit yet.Dimpled shoulders and sleeves deal with boundary-layer aerodynamics while a smooth body is deployed to reduced skin friction and reduce drag to as little as possible. The suit offers up to a 3% saving compared to the San Remo race suit at higher speeds, particularly between the 45-65 km/h range, speeds at which races are won and lost. While comfort wasn't the main focus for the BTW, Castelli still uses highly breathable, full-stretch fabrics. An increase in Lycra® content gives a super-snug fit, albeit with a slight reduction in wicking performance. And it doesn't have the same front opening as the San Remo suit, so pee stops are a bit more challenging. But it's a fast suit, and that's what counts. Progetto X² Air Seat PadThe top-end Progetto X2 Air Seatpad is now better than ever. Castelli has improved the shape of the back and improved the method of stitching it in place. The result is it now sits flatter and offers greater comfort.The X2 retains its awesome ventilating perforations, keeping you cooler and drier on endurance rides. The design allows air and moisture to flow directly to the surface fabric for quick evaporation maintaining dryness. A 3-layer component construction also features two densities of foam plus gel pads to provide progressive damping. A super-soft and stretchy next-to-skin layer, with an antibacterial finish, completes this premium pad.Features:Materials: 65% Polyamide, 34% Elastane. 1% PolyesterTop: 86% Polyester, 14% ElastaneMade to be the fastest option for high-speed road racingDimpled shoulder and sleeve fabric for boundary-layer aerodynamicsSmooth body for reduced skin friction and laminar flowPremio-based short portion for aero comfortProgetto X² Air seamless seat pad for all-day comfort2-way YKK® zipperLasered tone-on-tone logos at back of leg and stitched scorpion patch at top of backSleeves to hold numbers over 2 rear pocketsSuggested temperature range: 15 to 35 degrees CBuy Castelli Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.

The pulley wheels are the fastest spinning bearings on your bike, making an upgrade to CeramicSpeed an effective way to save you precious energy. They are extremely wear resistant and will outlive any pulley you have previously ridden. Titanium pulley wheels are extremely resistant to wear. This makes them a great choice if you ride in demanding conditions or just ride a lot. To give even greater protection and reduced friction, a super thin protective coating is applied to the bearing races. This further increases the resistance of the bearing to corrosion or damage from foreign objects. Combining coated bearing races with a titanium pulley wheel creates a pulley wheel with extreme properties in terms of wear resistance and performance. CeramicSpeed titanium pulley wheels are specially designed to reduce friction to an absolute minimum, virtually eliminating the drag associated with standard pulley wheels. The special design helps guide the chain in its ideal line and perform super smooth shifting.
