CeramicSpeed Oversized Pulley Wheel System Coated Rear Derailleurs
  • £329.99
  • RRP £445.99
  • Saving you £26

The cage is made from carbon fibre and reinforced PA while the 17-tooth pulley wheels are made from aluminium and mounted with high quality CeramicSpeed coated bearings. The revolutionary OSPW System is mounted with CeramicSpeed coated bearings, which means it has undergone a special coating treatment to provide even more protection and lower friction. A very thin protective coating is applied to the bearing races, which further increase the resistance to corrosion or damage from foreign objects. The OSPW has been tested and confirmed to be the world’s fastest pulley wheel system, therefore enhancing your performance with free speed, which gives you a more efficient drivetrain. Like all other products delivered by CeramicSpeed, this product has undergone a thorough testing program and is used by professional triathletes Tim Don and Tyler Butterfield. Maintenance It’s important that you properly lubricate your bearings in order to ensure optimal performance and maximum longevity. Add oil to the outside of the bearing seal, so that oil can penetrate the bearing. Do this when you lubricate your chain, or if you have washed your bike or have been riding in wet or muddy conditions.

Castelli Free Speed 2 Race Tri Short Sleeve Cycling Jersey
  • £125.00

The Right Race Jersey For Speed And ComfortSome triathletes choose long sleeves for the extra speed. Some for the comfort. Some for sun protection. This jersey gives you all three.The aerodynamic speed is unmatched. It's what Castelli does best. We have a year-round testing and development program with the Norwegian Technical University in Trondheim to make our race gear the slickest around.The comfort is what comes from our expert pattern engineers and soft performance Italian fabrics. We reduce the number of seams so that there is less chafing and less to bother you when you should be concentrating on pounding out the run.Sun protection ... well, you've trained untold hours for this day. We focus on speed, but we still manage to block 94% of UV rays with our back Velocity mesh fabric that doesn't compromise speed, comfort or breathability. You may want to add some sunscreen, but this fabric provides UPF 16 protection, which is a significant help. Your cotton T-shirt is probably UPF 8.Take note of the well-thought-out details: Castelli's generous two pockets lie flat but hold a lot of gear and nutrition. The SnapLock fasteners clip to Castelli shorts to prevent the top from riding up during the swim or bike.Key Features: Freedom of movement in the water, aerodynamics on the bike, comfort on the run, Velocity Rev2 aero fabric on front-facing surfaces, UPF 16 Velocity mesh back blocks 94% of UV light with generous breathability, 2 rear pockets lie flat and prevent nutrition from bouncing around, GIRO3 flat gripper elastic lies flat on lower back, SnapLock fastener at lower back to clip to Free Tri Short to prevent riding up during swim or bike leg, YKK® Camlock® zipper, Elbow-length sleeves for maximum aerodynamics.

Castelli BTW Speed Suit SS22 - Black - XS}, Black
  • £270.00
  • RRP £300.00
  • Saving you £10

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.
