Cycling Bargains - Shimano Dura-Ace R9100 Groupset (11 Speed) - Another £100 off - Some Gear combinations will cost more.
The 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 Crankset The 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. Crankset Features: Enhanced design saves 7g while maintaining rigidity Iconic 4-arm construction maintains high rigidity and reduces weight Optimised crank arm design strengthens key stress zones New chainring tooth profile is adapted for race bike specific disc brake systems Accommodates shorter chainstays (410mm) with 135mm OLD Hollowglide chainring construction maintains smooth shifting whilst reducing weight and increasing stiffness Dura-Ace R9100 2x11 Speed STI Shifter Set Like 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. Shifter Set Features: Pattern hood design offers better grip in all conditions Quick and intuitive rear shifting operation Shorter lever stroke Redesigned internal shifting unit Lighter front shifting operation Comfortable grip and operation More customisable and precise lever position Expanded reach adjustment range (14mm) Weight: 365g (Pair) Dura-Ace R9100 Rear Derailleur The 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. Rear Derailleur Features: Maximum Sprocket: 30T Minimum Sprocket: 11T Maximum Front Difference: 16T Total Capacity: 35T Stable shifting performance Pulley maintains the same distance to the cog as you shift Shimano Shadow RD construction Low profile rear derailleur design Race endurance for less damage in crash Adapted for race specific frame design Weight: 158g Dura-Ace R9100 11 Speed Braze On Front Mech The 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. Front Mech Features: Top Gear Teeth: 46-55T Chainstay Angle: 61-66 Chain Line: 43.5 Lighter and intuitive shifting operation Natural front shift lever stroke More ergonomic power curve Precise
