Shimano Dura-Ace R9100 11 Speed Groupset

Shimano Dura-Ace R9100 11 Speed Groupset

Shimano Dura-Ace R9100 11-Speed GroupsetThe jewel in Shimano's crown, the Dura-Ace range does not need an introduction. Favoured by the majority of teams in the pro peloton, the Dura-Ace 11-speed groupset emulates its predecessor. Every component in this Dura-Ace groupset has been re-engineered for optimal weight savings alongside maximum energy output with minimal loss through friction or non-compliant components. The result is a beautiful marriage of stiffness with weight-savings Dura-Ace R9100 CranksetThe Shimano Dura-Ace R9100 Crankset received a complete re-design. Now featuring Shimano's iconic 4-arm hollow spider that is made from hollow-forged aluminium, the crankset has a perfect balance of low weight and stiffness Despite looking visually bigger, the overall weight of this Dura-Ace crankset has decreased by seven grams and compliments an increase in stiffness. This Dura-Ace crankset has evolved and can be teamed with disc brake road bikes Dura-Ace R9100 Crankset Features:Enhanced design saves 7g while maintaining rigidityIconic 4-arm construction maintains high rigidity and reduces weightOptimised crank arm design strengthens key stress zonesNew chainring tooth profile is adapted for race bike specific disc brake systemsAccommodates shorter chainstays (410mm) with 135mm OLDHollowglide chainring construction maintains smooth shifting whilst reducing weight and increasing stiffnessDura-Ace R9100 2x11sp STI Shifter SetLike the crankset, these Dura-Ace 9100 shifters have received an overhaul to improve ergonomics and shifting efficiency. The re-designed brake hoods are now more comfortable to grip, especially for those with smaller hands. The shifters also offer up to 14mm of reach adjustment The rear shifter features an improved lever stroke that is shorter than previous editions. This allows for quicker shifts and requires less effort from the rider. The front shifter features a lighter lever swing for a more linear stroke Dura-Ace R9100 2x11sp STI Shifter Set Features:Pattern hood design offers better grip in all conditionsQuick and intuitive rear shifting operationShorter lever strokeRedesigned internal shifting unitLighter front shifting operationComfortable grip and operationMore customisable and precise lever positionExpanded reach adjustment range (14mm)Weight: 365g (Pair)Dura-Ace R9100 Rear DerailleurThe Dura-Ace R9100 rear derailleur takes the Shadow technology from its mountain bike range and introduces it to the road. The shadow design places the rear derailleur under the chainstay and cassette to give a slimmer profile, which not only helps with aerodynamics but also offers extra protection in crashes The Shadow design offers faster wheel changes thanks to the fact that it moves the derailleur out of the way of the dropouts. It also offers faster and more precise shifting than ever before Dura-Ace R9100 Rear Derailleur Features:Maximum Sprocket: 30tMinimum Sprocket: 11tMaximum Front Difference: 16tTotal Capacity: 35tStable shifting performancePulley maintains the same distance to the cog as you shiftShimano Shadow RD constructionLow profile rear derailleur designRace endurance for less damage in crashAdapted for race specific frame designWeight: 158gDura-Ace R9100 11-speed Braze On Front MechThe Dura-Ace R9100 front mech has been redesigned to be smaller, more efficient and provide faster and crisper shifting. The internal toggle mechanism provides greater clearance for larger tyres and it now features a built in cable tension adjustment bolt meaning there is no need for inline barrel adjusters Dura-Ace R9100 11-speed Braze On Front Mech Features:Top Gear Teeth: 46-55tChainstay Angle: 61-66Chain Line: 43 5Lighter and intuitive shifting operationNatural front shift lever strokeMore ergonomic power curvePrecise & easy front derailleur set upMore cable routing optionsIntegrated cable tension adjustmentNew link (Toggle) construction means there is no need for TL-FD90 and turning converter assemblingAdjustable cable tension on the front derailleurAdapted for race specific frame designWeight: 69gDura-Ace R9100 Road Brake Caliper SetThe Dura-Ace 9100 brakes have been developed to offer greater tyre clearance for up to 28c tyres while still maintaining the aerodynamic advantage of previous editions. They are now also up to 43% stiffer than previous Dura-Ace brake calipers and offer a linear braking curve for improved feel and function Dura-Ace R9100 Road Brake Caliper Set Features:Mount Type: SLR EV Dual PivotThe best balance between rigidity, weight and stopping powerMore predictable, linear braking curveClear contact feeling with better linearityMore aerodynamic QR leverSleek designLess gap between each armBetter clearance with wider tyre (up to 28c)Weight: 326g (Pair)Dura-Ace R9100 CassetteShimano have retained the traditional close ratio cassettes from previous editions of Dura-Ace, but with the new R9100 groupset they have introduced a wide range 11-30T cassette. All cassettes in the range will be compatible with the one rear derailleur so you can easily swap your cassettes out based on terrain The cassette is manufactured from a lightweight alloy and carbon fibre spider that houses alloy sprockets. The 5 largest sprockets are manufactured from titanium to keep the weight low. The sprockets are also extensively cut away and drilled to further reduce weight without reducing rigidity The very best and quickest shifts are optimised thanks to the Hyperglide EV sprockets that have a computer designed tooth configuration with contoured shift gates Dura-Ace R9100 Cassette Features:Hyperglide EV sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under loadClose ratio gearing allows a more efficient use of energy through finer cadence controlLargest sprockets are mounted on lightweight alloy and carbon carriers to reduce weight and increase rigidity5 largest sprockets are made from titanium to reduce weight without sacrificing strengthSprockets are extensively cut away and drilled to further reduce weight without reducing rigidityNickel-plated finish offers hard wearing resistance to corrosionAlloy cassette lockringWeight: 175g (11-25t), 193g (11-28t), 211g (11-30t), 189g (12-25t), 205g (12-28t)Dura Ace 11-speed Chain CN-9000 114 LinksThe new symmetrical 11-speed Dura-Ace chain uses hollow pins for a light weight, PTFE coating for smooth shifts and offers increased durability Dura Ace 11-speed Chain CN-9000 114 Links Features:PTFE coatingIncreased durability (vs. CN-7900)Weight: 243gPlease note that this groupset does not come supplied with outer cables.A 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products) Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
