Shimano Sora R3000 2x9 Speed Gear-Brake LeversEngineered for road bike adventures, these 2x9 speed dual control levers provide smooth and dependable shifting operation on every ride. Coming equipped with an adjustable lever reach, these can be fine-tuned to perfectly match your hand size, riding style and the terrain conditions. Shimano has also ensured that both shifting and braking can be controlled from each lever, which frees up valuable handlebar space.Features:Use: RoadSpeed: 2x9 speedShift Lever Outer Casing: OT-SP41Shift Lever Outer Casing RD Side: OT-SP41 SealedNew Super SLR: YesHidden Brake and Shift Cables: YesClamp Band: 23.8 - 24.2mmReach Adjust: ScrewLever Type: Dual Control LeverSingle or Pair: PairPart Numbers: STR3000DPATechnologies:Optislick: OPTISLICK cables feature a minimal and uniform electrically coated layer that improves cable routing efficiency and provides excellent corrosion resistance.New Super SLR: SLR stands for SHIMANO Linear Response. The NEW SUPER SLR design makes use of a friction-reducing mechanism in the caliper, lever and cable that improve response and modulation. Also for the lever, the SERVOWAVE mechanism is adopted to provide quick contact of shoe to rim and longer stroke from the initial braking effect for better control. SLR is the essential factor in the SHIMANO dual-pivot caliper that deliver more braking power than conventional side-pulls.Dual Control Lever: DCL stands for DUAL CONTROL LEVER. It has brake and shifting functions in the system and enables easy operation. Ergonomic innovation is probably more critical to the higher standard performance than the added gearing. The shift internals borrow the robustness from our MTB technology and are so smooth and effortless that one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of SHIMANO TOTAL INTEGRATION, and simply has to be experienced to be understood.SP41: With OT-SP41 the entire length of the outer casing is pre-lubricated with a special silicone grease for quick and precise shifting performance. OT-SP41 maximally reduces the inner cable friction to provide quick response to operations and easy/effortless shifting. Moreover, power loss due to delay in shifting and fatigue by shifting especially when you ride on the terrain with many ups and downs as well as a long distance is also reduced. 8 color options are also available for outer casing to meet many requests.Reach Adjust: Brake lever is equipped with a reach adjust mechanism. The distance from handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences.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.
RX810 series cranks offer Shimano’s widest-ever delta between small and large chainrings, a 17-tooth gap, that also debuts the company’s first ever 48-31T option. This, when paired with the available 11-34 cassette, offers an exceptionally low climbing gear while maintaining a 48-11 ratio that allows riders to take advantage of strong tailwinds and long descents. RX810 series cranks also are available in a single chainring option for those who prefer the simplicity and decreased weight of a 1x11 drivetrain with one of Shimano’s wide ratio 11-40 or 11-42T cassettes. All GRX cranksets use a new, +2.5mm chainline for increased tire and frame clearance.Choice. Shimano’s new GRX line is all about choice. Shimano doesn’t want to pigeonhole the way you ride, or decide for you what the best solution is for your riding style. While we’ve long been fans of double chainring drivetrains, we also recognize the value of a single chainring system. With GRX, Shimano offers both, each with gearing options that allow you to tailor your drivetrain to suit your tastes.With two different derailleur cage lengths, Shimano GRX ensures stable shifting and chain retention across a wide range of gearing options. Looking for maximum range while maintaining road cassette progression? Go with GRX’s 800 series 2x11 RD-RX810 or Di2 RD- RX815 rear derailleurs, designed for close ratio clusters, with 48/31 chainrings and an 11-34 cassette. Paired with 700c x 40mm tires, it delivers a top gear similar to a road bike with 25mm tires and a 50 x 11 gear. And on the low end, with its 31 x 34 combination, you get a gear that early mountain bikers would envy. It is the lowest gear currently on offer for premium road drivetrains (aside from Shimano’s own GRX 2x10 30-36 offering), perfect for climbing loose, dirt and gravel surfaces.Want to drop some weight, simplify your shifting, and still maintain a versatile range? Consider the 1x11 GRX option with either Shimano’s 11-40 or 11-42 cassette and a 40 or 42-tooth equipped crankset, shifted by a RD-RX812 or Di2 RD-RX817 wide ratio rear derailleur. You’ll lose a little, absolute top speed, but still love the 1:1 low gear ratio. If you live in an area without sustained or steep climbs, you might love the smaller gear steps of that same 1x11 front chainring with an 11-34 cassette. Options abound.What about when the weather turns autumnal and you contract a case of cyclocross fever? GRX 1x11 can quickly transform from gravel fun to CX focused with the change of a cassette.No matter the option you select, GRX rear derailleur offerings feature Shimano’s SHADOW Plus chain stabilizer that can be turned on or off depending on conditions. SHADOW Plus revolutionized the mountain bike world and now it’s been tuned for gravel and rough road riding in GRX. With a quieter drivetrain, SHADOW Plus helps you engage with your surroundings and enjoy time outside.Today’s gravel riders demand more of their bikes and of themselves.
