Ready for long days on the road, this wheelset is equipped with a hard-wearing aluminium rim construction, which offers an excellent combination of strength, durability and performance as you clock up the miles. Fulcrum has also kitted out this model with an asymmetric rim design that's engineered to improve rim tension, balancing the forces from your disc brakes and sprocket cassette. Another highlight is its 24 rounded straight-pull stainless steel spokes, which ensure smooth and stable rolling performance as you go the extra distance. Coming complete with sealed cartridge bearings and many of the brand's finest technologies including 2-Way Fit, this is a great choice of upgrade for low rolling resistance, increased grip and greater protection thanks to its tubeless compatible design. Endurance Road Bike Wheelset The Racing 5 DB wheels are the perfect choice for endurance bikes. The lower aerodynamic resistance and decreased stiffness, achieved with the lower 24mm U-shaped profile, makes them the ideal technical choice for long rides without having to worry about climbing, rain or wind, with a consequent saving in energy and increased comfort. 2 Way Fit Ready Technology In this case to the aluminium rim has seen an increase in the inner channel width, up to 20mm from the previous model’s 17mm, and the addition of the innovative 2 Way Fit system, to comfortably fit 25-28 mm tyres, both clinchers and tubeless (tubeless tape installed and valves included). Laser-Etched Graphics The aesthetics have undergone the same intervention as the Racing 4 DB model, with the updated laser-etched graphics, ensuring the long life of their striking design.

The Fulcrum engineers have redesigned the spokes and the hub housings to create a solid and unmoveable whole. The result is that the spokes will never lose their initial tension, thus keeping the wheel perfectly reactive and centred.

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.
