Shimano Dura-Ace Di2 RD-R9150 11-Speed Rear Derailleur Black One Size #ad

Shimano Dura-Ace Di2 RD-R9150 11-Speed Rear Derailleur Black, One Size

Shimano Dura-Ace Di2 RD-R9150 11-Speed Rear Derailleur Black, One Size #ad - As with other shimano di2 bits, the dura-ace rear derailleur is compatible with shimano’s rust-, stretch-, freeze-, and generally worry-free e-tube wiring system. It situates the chain squarely on every cog and it jumps between those positions with startling speed. The shifting itself is peerless, as the derailleur always knows where it is, so its travel isn’t restricted or lengthened by imperfect cables. By putting the rear and front derailleurs in communication with each other, synchronized shift can actually calculate your efficiency and perform simultaneous front and rear shifts to eliminate cross-chaining and set you up in the best chain line for any given gearing. Enabling synchronized shift lets the di2 system work its magic to automatically shuttle your chain from cog to cog without any input from you and intelligently manage the fleet of cogs at the aft-end of your drivetrain. These shifting patterns depend on the direction you’re shifting and the combination you’re shifting into, and they’re also programmable via shimano’s e-tube system, so you can set your preferences in advance to ensure that your internally communicating drivetrain isn’t conspiring against you. Shimano’s new dura-ace di2 rd-r9150 11-speed rear derailleur boasts a sleek profile that practically hides from the wind and finally brings the synchronized shift functionality honed in the trail-focused xtr di2 system onto the road. That said, it isn’t a requirement to use, so the traditionalists among us will breathe a sigh of relief that this derailleur also allows the same precise, manually controlled and customizable shifting we’ve come to expect from di2. Its modularity makes it easy to set up on virtually any frame, though it does cohabitate with less friction when the frame is built with di2 in mind.

 

Shimano Dura-Ace R9150 Di2 11-Speed Braze-On Front Derailleur #ad

Shimano Dura-Ace R9150 Di2 11-Speed Braze-On Front Derailleur

Shimano Dura-Ace R9150 Di2 11-Speed Braze-On Front Derailleur #ad - This function also prevents the mere thought of chain rub for a smooth, quiet ride in every gear combination. Aside from some slightly modified aesthetics and a 10g reduction in weight, the shimano dura-ace di2 fd-r9150 11-speed front derailleur carries over the high functioning precision of its 9070 predecessor. This feature adjusts the position and angle of the front derailleur, on-the-fly, and eliminates the possibility of dropping the chain under heavy shifts up or down the chainrings, regardless of how cross-chained that you may be. The front derailleur has always been our favorite component of the di2 series, reinforced by years of mechanical systems throwing chains at inopportune moments on climbs and winding up for sprints. Di2 makes thrown chains a part of history with fast, silent, and accurate chain movement boosted by shimano’s automatic trimming function. While the new 9150 rear derailler gets all the attention for its mountain-inspired changes, the front derailleur sits stealthily by as the brains of the di2 system, ensuring fast, reliable, and customizeable gear shifts whether you’re off to the coffee shop for the sunday social ride or hammering the pedals at the pointy end of the peloton.

Shimano Dura-Ace R9100 11-Speed Braze-On Front Derailleur #ad

Shimano Dura-Ace R9100 11-Speed Braze-On Front Derailleur

Shimano Dura-Ace R9100 11-Speed Braze-On Front Derailleur #ad - Key big ring shifts in the heated moments of a race are no longer just possible within a strict set of parameters now, you’ll only have to lift a finger. The resulting dura-ace fd-r9100 11-speed front derailleur delivers concrete improvements to its predecessor’s shortcomings, behaving far more consistently than the often moody than some of its predecessors, whose changes in attitude could be set off by cable entry angles and cable tension that didn’t suit it. Plus, the derailleur’s more compact internals mean that the entire body has shrunk, increasing clearance and eliminating the infuriating cable rub that has irritated many of us to our limits at some point in our cycling careers. The design embraces multiple routing options that its previous version wouldn’t dream of allowing, and requires low rider effort to generate precise, crisp shifts. Across dura-ace 9100, shimano made subtle, rather than monumental, shifts in design to improve a system that was already pretty damn good. Proving that mechanical drivetrains can–and still should–be improved, shimano focused most of its attention on the derailleurs, making the biggest changes to ride experience with important tweaks to both the front and rear derailleurs’ designs. No, shimano found a way to redesign the body of the derailleur, equipping it with a new linkage system and integrated cable tension adjuster that does away with the need for a barrel adjuster. How’d they do it not by magic, though sometimes we wonder.

 

Shimano XTRDura-Ace CN-HG901 11-Speed Chain One Color 11-Speed #ad

Shimano XTR/Dura-Ace CN-HG901 11-Speed Chain One Color, 11-Speed

Shimano XTR/Dura-Ace CN-HG901 11-Speed Chain One Color, 11-Speed #ad - Keeping your bike shifting with crisp precision, the shimano xtr/dura-ace cn-hg901 11-speed chain pairs brilliantly with the brand’s top-flight xtr and dura-ace 11-speed drivetrains. Ultimately, this allows you to focus on riding without worrying about your chain keeping up with rapid shifting and high-cadence efforts. The chain’s slight asymmetry pairs perfectly with shimano’s 9000 series drivetrains for silky-smooth gear shifts and greater power transfer, and the low-friction sil-tec treatment glides across your cassette’s cogs with minimal friction. It represents the very best among shimano’s line, which puts it in the running as the best chain, period. This year’s model features a revised plate profile that’s compatible with e-bikes and single-speed applications. It’s no longer vulnerable to separations in the aforementioned applications because it’s able to withstand the higher torque generated by e-bikes.

 

Shimano Dura-Ace Di2 ST-R9150 11-Speed Shifters Black Set #ad

Shimano Dura-Ace Di2 ST-R9150 11-Speed Shifters Black, Set

Shimano Dura-Ace Di2 ST-R9150 11-Speed Shifters Black, Set #ad - Both shifters allow a customizable shifting experience dialed to your riding style and requirements, including the ability to dump through multiple gears–or even the entire cassette–with one shift movement. The lever blades and paddles see an outward curve and feel that’s slightly more pronounced than in the prior generation, which makes for a more positive interaction from either the hoods or drops. Shimano even claims that this version might even be a little bit faster, but frankly, we have a hard time qualifying that claim when we’re out on the road. As the rest of the industry scrambles to catch up, shimano’s di2 groupsets continue to set the standard for precise electronic shifting with nearly endless customizability. The release of 9150 is the next evolution of di2, bringing slightly updated aesthetics and even better shift functionality to your next ride. And for the proverbial icing on the cake, when paired with the new 9150 rear derailleur, these shifters are now capable of performing shifts up to a 30t cog on the cassette. The shimano dura-ace di2 st-r9150 11-speed shifters sit at the helm of your cockpit to drive precise shifts exactly when you need them. Aside from those tweaks, the dura-ace 9150 shifters deliver the precise, swift gear changes we’ve come to expect from di2. The hoods take on a similar shape to 9070, but with a few slight tweaks for improved comfort when your hands are on the hoods. Made from a dual-compound rubber composite, the low-volume hood design retains the slightly perforated form of 9070 and makes lever accessibility easy. Shimano also incorporates a more noticeable “click” feeling when shifting, which addresses the almost too-stealthy shift feel that was one of the few complaints we’ve fielded about previous di2 systems.

 

Shimano Dura-Ace SM-RT900 Rotor - Centerlock One Color 160mm #ad

Shimano Dura-Ace SM-RT900 Rotor – Centerlock One Color, 160mm

Shimano Dura-Ace SM-RT900 Rotor – Centerlock One Color, 160mm #ad - The shimano dura-ace sm-rt900 rotor prevents brake fade on extended descents where you’d normally experience a major decrease in stopping power on the road. They’re compatible with frames that accommodate flat-mount disc brakes and attach to shimano’s proprietary centerlock hub system. This freeza rotor is part of shimano’s newest dura-ace hydraulic disc brakes, meaning they’re compatible with the dura-ace br-r9170 caliper and ice-tech pads. The 3-layer rotor construction has a stainless steel braking surface with an alloy core featuring finned cut-outs for effective heat dispersion. Shimano claims heat is reduced by up to 50-degrees celsius, which is significant when you’re riding along mountainous terrain where sustained descents pose a threat to your stopping power.

Shimano Dura-Ace OT-SP41 Polymer-Coated Derailleur Cable Black, One Size

Shimano Dura-Ace OT-SP41 Polymer-Coated Derailleur Cable Black, One Size #ad - Slow shifting is a bummer, and there are lots of reasons for it, but if you’ve eliminated derailleur problems, cassette issues, and general grime as the culprits, it might be time to replace your shift cables and housing with shimano’s dura-ace ot-sp41 polymer-coated derailleur cable. Even the end caps are sealed, which prevents dirt and grime from sneaking in and gunking up the system. The housing is pre-lubed with silicone grease for smooth, stick-free shifting, and the polymer coating on the cable allows it run even more smoothly.

Shimano Dura-Ace PD-9000 Carbon Road Pedal BlackGrey #ad

Shimano Dura-Ace PD-9000 Carbon Road Pedal (Black/Grey)

Shimano Dura-Ace PD-9000 Carbon Road Pedal (Black/Grey) #ad - Given the carbon composite body in the new dura-ace pd-9000 pedals, we’d have to say that shimano found carbon a fitting substitute for its long-tenured alloy designs. Dubbed the smh-12, the cleat provides just one degree of float. While other component manufacturers have jumped excitedly on the carbon fiber bandwagon, shimano has remained committed to the use of metals in its components, only utilizing carbon where it felt the material offered a distinct benefit. The biggest difference in this iteration is the cleat and how it interacts with the pedal. Now, that’s certainly not much, but if your bike fit is as it should be, it will keep your leg in perfect alignment, and minimize strain on your knees and muscles.

While still saving weight without giving up strength, this chain offers higher durability, silent pedaling, and reduced chain drop even under intense pressure.
